Letter to Our Shareholders

**DEAR FELLOW SHAREHOLDERS,**

On behalf of Leidos and our Board of Directors, I want to thank you for your continued support. Each year, I look forward to this opportunity to extend my gratitude to you and reflect on our accomplishments. In 2022, we took Leidos to new heights, adding to our portfolio and capabilities, celebrating big wins, and growing the business in new directions.

Leidos achieved revenue of $14.4 billion for FY22, a 5% increase from the prior year. In June, the Government Accountability Office upheld our $11.5 billion Defense Enclave Services contract win, the largest in company history. Our medical exam business won two substantial contracts to support service members transitioning to civilian life and veteran status, and we continued our work on autonomous Navy vessels and were selected to design and build a medium uncrewed undersea vehicle. We acquired Cobham Aviation Services Australia's Special Mission business this past Fall. This deal builds on our global airborne ISR capabilities, and we now provide airborne border surveillance and search and rescue services to the Australian Federal Government. We continue to innovate in the cutting-edge arena of hypersonics, winning key contracts to develop an air-breathing system and increase flight test capacity. We also notched important contract wins that have positioned our company for sustained success. These are just a few examples of how we have captured new opportunities to serve our customers.

As a global company, our work and those who rely on our success bring greater meaning to our mission. With the ongoing war in Ukraine, our employees steadfastly supported our customers' missions by providing devices, equipment, supplies, and humanitarian aid. We also partnered with Project HOPE, a non-profit organization generating much-needed medical services and assistance to the people of Ukraine.

One of my top priorities as CEO was building on Leidos's unique culture and making it a great workplace. In 2022, we were named to the Drucker Institute's list of the 250 Best Managed Companies, Newsweek's Greatest Places to Work for Diversity, Fortune's Most Admired Companies, Best Employers for Veterans by Forbes, and Ethisphere's Most Ethical Companies List for the sixth consecutive year. These accolades are only possible through sustained, top-down commitment to our company's values. We have done just that.

It is bittersweet that I am writing this letter to you for the last time this year. On February 27, I announced my retirement from Leidos by May 2023. Serving as your Chairman and CEO for the past nine years has been an honor and a privilege. The Board of Directors has appointed Thomas Bell as the incoming CEO. Tom's exceptional track record leading Rolls-Royce North America and expertise in our industry and emerging technologies will be a tremendous asset to Leidos as we continue to drive growth and innovation. I look forward to working with Tom and new Board Chairman Robert Shapard through the transition while watching the next chapter of Leidos take hold under their leadership.

Leidos had a great 2022 and has a bright outlook for 2023 and beyond. Our 45,000 employees start their days ready and committed to solving the world's toughest challenges – making it safer, healthier, and more efficient. I am incredibly proud of our team's efforts and look forward to watching the next chapter of Leidos unfold. Thank you for your continued support and trust.

Sincerely,

![ldos-20230315_g10.jpg](ldos-20230315_g10.jpg)

**Business Performance Highlights for 2022 Relating to Pay**

Our business performance in 2022 was strong. We ended fiscal 2022 with reported revenues of $14.4 billion, an increase of 5% compared to the prior fiscal year. Our performance validated that our diversified and resilient portfolio and our investments in technology and innovation are positioning us for growth in key customer missions, including digital modernization, cyber, hypersonics, and force protection. Against a challenging backdrop in fiscal 2022, we delivered on our financial commitments to investors, allocated capital to deliver value for our stockholders, won multiple franchise programs that position us for future growth, and significantly grew our talent base.

The information below are the performance metrics that form a significant part of our 2022 compensation targets. We achieved 100% of our total backlog compensation target, giving us a strong foundation for growth. Adjusted operating income reached 98% of compensation target. We also achieved 101% of our free cash flow compensation target, reflecting strong performance across our operational segments. We provide additional information regarding these compensation metrics, including a definition of such metrics and adjustments made for our compensation programs from the reported metrics, in "Annual Cash Incentive Awards for Fiscal 2022" on page [55](#ifaf8319aa3bc497da1521cf9f4ba62e8_210638)<sup>(1)(2)</sup>.

In 2022, we expanded our flagship social purpose campaign: Mission for the Mind: Advancing Mental Health Solutions. Leidos is committed to prioritizing the mental health of employees, their families and the broader communities where we operate. As part of this effort we expanded our partnership with the Milken Institute Center for Public Health to help accelerate our ongoing CEO Pledge to end Addiction efforts. More than 150 CEOs and senior leaders have signed the pledge. Core to the relationship is a Collaborative Action Group created to reach more employees and communities, especially in light of how the COVID-19 pandemic has exacerbated substance abuse and harmed mental health and well-being globally.

The program focuses on:

▶Anti-opioids and substance use disorder prevention;

▶Anxiety, depression and COVID-19-related impacts; and

▶Suicide prevention efforts, especially related to veterans and the emerging vulnerable population of healthcare workers.

We maintain the Leidos Well-Being Champion Network, which is comprised of employees across the United States and United Kingdom who support employee health, well-being and work-life balance. The ambassadors promote four key pillars: Mental, Physical, Financial & Social Well-Being to ensure visibility and access at all levels across the business. We also worked with our pharmacy benefit management organization and dental insurance provider to promote safer use of opioids with the goal of reducing the likelihood that a Leidos employee or a family member will develop an opioid use disorder. Leidos continues to provide significant support to non-profit organizations in this area each year, having already contributed millions of dollars to substance misuse and mental health charitable efforts.

**BOARD COMPOSITION OVERVIEW**

Each year, the Corporate Governance and Ethics Committee reviews the composition of the Board to assess the qualifications and areas of expertise needed in directors to enhance the Board's exercise of its duties. In evaluating potential nominees, the Committee and the Board consider each individual in the context of the Board as a whole, with the objective of recommending to stockholders a slate of individual director nominees that can best continue to oversee the success of our business and advance stockholders' interests.

In addition, the Corporate Governance and Ethics Committee will consider candidates with a diversity of race, ethnicity and/or gender, and will ensure that such candidates are included in each pool from which Board nominees are chosen. The Board is committed to ensuring that it remains composed of directors who have the appropriate skills to oversee the success of the business and striving to maintain an appropriate balance of diversity (including gender diversity), experience, and tenure in its composition, and intends to increase the proportion of gender and racially/ethnically diverse directors over the next few years. For additional information regarding our director nominees and our criteria for Board membership, see "Nominees for Election to the Board of Directors" on page [19](#if4d032a615334d44ab5a038068275fdc_401) and "Criteria for Board Membership" on page [18](#ide8c7920bcf9478cb0b6815a22cd42a8_9254).

**CORPORATE GOVERNANCE HIGHLIGHTS**

Leidos recognizes the importance of strong corporate governance to address the interests of our stockholders, employees, customers, supplier partners and other stakeholders. We believe that strong corporate governance is critical to achieving our mission and long-term stockholder value. The following table highlights certain of our corporate governance practices and policies:

▶Independent Chair following the 2023 annual meeting with robust and well-defined responsibilities

▶Executive session during every Board meeting led by the Independent Chair following the 2023 annual meeting without management present

▶No supermajority stockholder voting requirements in our charter or bylaws

▶Proxy access right for stockholders

▶Annual election of all directors

▶Majority voting with resignation policy for directors in uncontested elections

▶Annual Board and Committee evaluations, periodic, third-party facilitated evaluations

▶Risk oversight by Board and Committees

▶Independent directors focus on executive succession planning

▶Independent Committee chairs

▶Annual advisory vote on executive compensation

▶Meaningful stock ownership requirements for directors and executives

▶Robust board refreshment process, including a focus on skills, diversity and ethics

▶Annual review of Committee charters and Corporate Governance Guidelines

As previously announced, the Board expects to split the roles of CEO and Chair after the 2023 annual meeting of stockholders, and appoint Mr. Shapard as the independent, non-executive Chair of the Board. Our Board believes that this leadership structure is appropriate at this time because it effectively allocates authority, responsibility, and oversight between management and independent members of our Board.

**STOCKHOLDER ENGAGEMENT**

Throughout the year, members of our Investor Relations team and our business leaders have engaged with many of our top stockholders to seek their input and feedback, remain well-informed regarding their perspectives, and help increase their understanding of our business. Management also routinely engages with investors at conferences and other forums. This outreach complements our Investor Relations team's numerous touchpoints with stockholders each year. Depending on the circumstance, one or more independent directors may also engage in these conversations with stockholders. In addition, our Board receives reporting on a quarterly basis related to feedback from investors, as well as stockholder voting results.

We maintain an ongoing dialogue with our stockholders about our:

▶business strategy

▶market positioning

▶financial performance

▶corporate governance

▶human capital management

▶diversity and inclusion

▶ESG matters

**EXECUTIVE COMPENSATION OVERVIEW**

We believe that executive pay should be largely variable, equity-based, and tied to preset performance goals, and this is demonstrated in our pay mix and design.

**EXECUTIVE COMPENSATION HIGHLIGHTS**

Our compensation programs seek to closely align the interests of our named executive officers with the interests of our stockholders. To achieve this goal, our programs are designed to:

▶Pay for performance by tying a substantial majority of an executive's compensation to the achievement of financial and other performance measures that the Board believes promote the creation of long-term stockholder value and position the company for long-term success;

▶Target total direct compensation at approximately the median among companies with which we compete for executive talent;

▶Enable us to recover, or "clawback," incentive compensation if there is any material restatement of our financial results or if an executive is involved in misconduct;

▶Require our executives to own a significant amount of our stock;

▶Avoid incentives that encourage unnecessary or excessive risk-taking; and

▶Compete effectively for talented executives who will contribute to our long-term success.

| At our last annual stockholders' meeting in April 2022, we held a non-binding stockholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our stockholders overwhelmingly approved the compensation of our named executive officers, with approximately 96% of stockholder votes cast in favor of our say-on-pay resolution. | &nbsp;&nbsp;&nbsp;&nbsp;**2022<br>Say-on-Pay**<br>**96%** | **3-Year Average**<br>**Say-on-Pay**<br>**95%** |

**2023 COMPENSATION PROGRAM**

Each year, we perform a comprehensive review of our executive compensation program in consideration of our performance, the performance of our peer group, historical pay information, market practices and trends, the market for talent, stockholder and other stakeholder feedback, and other relevant points of information to assess the program, executive compensation levels and pay design. We believe the changes for the 2023 compensation program are in the best interest of Leidos' stockholders, and are aligned with our pay for performance philosophy and the dynamic nature of executive compensation practices and developments in our business and industry.

**2023 Short-Term Incentive Plan**

Beginning in 2023, we will modify the design of our short-term incentive program to reflect new financial performance metrics and weighting and increase the maximum payout scale from 150% to 200% as well as lower the threshold from 60% to 50%.

**Board Overview**

**CRITERIA FOR BOARD MEMBERSHIP**

To fulfill its responsibility to identify and recommend to the full Board nominees for election as directors, the Corporate Governance and Ethics Committee reviews the composition of the Board to assess the qualifications and areas of expertise needed in directors to further enhance the Board's exercise of its duties. In evaluating potential nominees, the Committee and the Board consider each individual in the context of the Board as a whole, with the objective of recommending to stockholders a slate of individual director nominees that can best continue the success of our business and advance stockholders' interests. In evaluating the suitability of individual nominees, the Corporate Governance and Ethics Committee and the Board consider many factors, including:

▶Expertise and involvement in areas relevant to our business such as defense, intelligence, science, healthcare, technology, finance, government or commercial and international business;

▶Interpersonal skills, substantial personal accomplishments and diversity as to gender identity, age, race, ethnic background, sexual orientation, culture and experience;

▶Commitment to business ethics, professional reputation, independence and understanding of the responsibilities of a director and the governance processes of a public company;

▶Demonstrated leadership, with the ability to exercise sound judgment informed by a diversity of experience and perspectives; and

▶Benefits from the continuing service of qualified incumbent directors in promoting stability and continuity, contributing to the Board's ability to work together as a collective body and giving Leidos the benefit of experience and insight that its directors have accumulated during their tenure.

PROPOSAL 1: ELECTION OF DIRECTORS

**Retirement Age and Board Refreshment**

The Board recognizes the importance of periodic board refreshment and maintaining an appropriate balance of tenure, experience, and perspectives on the Board. The Board values the contributions of both newer views as well as directors who have developed extensive experience and insight into the Company during their service on the Board. Accordingly, the Board has established a retirement age for independent directors of 75 and has not granted any exemptions or waivers to this policy. The Board believes that the evaluation and nomination processes will ensure that the Company has a properly constituted and functioning Board and considers, at least annually, upcoming retirements, the average tenure and overall mix of individual director tenures of the Board, the overall mix of the diverse skills, knowledge, experience, and perspectives of directors, each individual director's performance and contributions to the work of the Board and its committees, along with other factors the Board deems appropriate as part of Board succession planning and the nomination of director candidates.

**Board Diversity Commitment**<br>The Board and the Corporate Governance and Ethics Committee value diversity of backgrounds, experience, perspectives and leadership in different fields when identifying nominees. The Board is committed to actively seeking directors who are diverse with respect to gender, race and ethnicity for the pool from which director candidates are selected. Presently, 5 of 12 Board nominees are women or come from a diverse background. The Board is committed to ensuring that it remains composed of directors who have the appropriate skills to oversee the success of the business and striving to maintain an appropriate balance of diversity, experience, and tenure in its composition, and intends to increase the proportion of gender and racially/ethnically diverse directors over the next few years. <br>

**Board Diversity Policy**<br>The Board's overall diversity is a significant consideration in the director nomination process and a component of our direction to the independent search firm that helps us identify potential candidates. The Corporate Governance and Ethics Committee will consider candidates with a diversity of race, ethnicity and/or gender, and will ensure that such candidates are included in each pool from which Board nominees are chosen.<br>

**Nominees for Election to the Board of Directors**

Set forth below is a brief biography of each nominee for election as a director and a discussion of the specific experience, qualifications, attributes or skills that led to the Board's conclusion that the nominee should serve as a director of our Company. The Board evaluates each individual in the context of the Board as a whole, with the objective of recommending to stockholders a group of nominees with complementary skills and a diverse mix of backgrounds, perspectives and expertise beneficial to the broad business of our Company. As previously announced, Mr. Krone is retiring and will not be standing for re-election as a member of our Board. Our Board membership criteria and director nomination process are described in the "[Corporate Governa](#if4d032a615334d44ab5a038068275fdc_1192)[nc](#if4d032a615334d44ab5a038068275fdc_1192)[e](#if4d032a615334d44ab5a038068275fdc_1192)" section of this proxy statement.

PROPOSAL 1: ELECTION OF DIRECTORS

**Majority Voting Standard in Uncontested Director Elections**

We have adopted majority voting procedures for the election of directors in uncontested elections. In an uncontested election, nominees must receive more "for" than "against" votes to be elected. Abstentions and broker non-votes are not counted as votes cast. As provided in our bylaws, a "contested election" is one in which the number of nominees exceeds the number of directors to be elected. The election of directors at the 2023 annual meeting is uncontested.

If an incumbent director receives more "against" than "for" votes, then such director is expected to offer to resign, effective upon the Board's acceptance, in accordance with our Corporate Governance Guidelines. The Corporate Governance and Ethics Committee will consider the tendered resignation and make a recommendation to the Board. The Board will consider the Committee's recommendation and disclose its decision to accept or reject the tendered resignation in a press release, Current Report on Form 8-K or some other public announcement.

Shares of common stock represented by properly executed, timely received and unrevoked proxies will be voted as instructed in the proxy. In the absence of specific instructions, the shares represented by properly executed, timely received and unrevoked proxies will be voted "for" each nominee. If any of the nominees listed above become unable to stand for election at the annual meeting, the proxy holders intend to vote for any person designated by the Board to replace the nominee unable to serve, or the Board may reduce its size.

**Limitations on Other Board Service**

The Corporate Governance and Ethics Committee reviews the director selection process annually. The Board expects a high level of commitment from its members and will review a candidate's other commitments and service on other boards to ensure that the candidate has sufficient time to devote to our Company. The Committee has adopted policies so that the independent directors may not serve on the boards of directors of more than three other publicly-traded companies. Employee directors may not serve on the board of more than one other public company, and any board membership of employee directors must be approved in advance by the Chief Executive Officer, the Chair of the Board or the Independent Lead Director (and, after the 2023 annual meeting of stockholders, the Chief Executive Officer or the Independent Chair of the Board), as appropriate. We expect our directors to advise the Chair of the Corporate Governance and Ethics Committee and the Chair of the Board before accepting membership on other boards of directors, accepting membership on any audit committee or other significant committee assignment (such as a lead or presiding director role) on any other board of directors, or establishing or materially changing other significant relationships with businesses, institutions, governmental units or regulatory entities that may result in significant time commitments or a change in the director's relationship to the Company. Moreover, directors are expected to act ethically at all times and adhere to the Code of Business Conduct of the Board of Directors.

**Director Independence**

The Board annually determines the independence of each of our directors and nominees in accordance with the Corporate Governance Guidelines. These guidelines provide that "independent" directors are independent of management and free from any relationship that, in the judgment of the Board, would interfere with their exercise of independent judgment. No director qualifies as independent unless the Board affirmatively determines that the director has no material relationship with us (either directly or as a partner, stockholder or officer of an organization with which we have a relationship). The Board has established independence standards set forth in the Corporate Governance Guidelines that include all elements of independence required by the listing standards of the New York Stock Exchange, or NYSE.

All members of the Audit and Finance, Human Resources and Compensation and Corporate Governance and Ethics Committees must be independent directors as defined by the Corporate Governance Guidelines. Members of the Audit and Finance Committee and the Human Resources and Compensation Committee must also satisfy separate independence requirements, which require that they may not accept directly or indirectly any consulting, advisory or other compensatory fee from us or any of our subsidiaries other than their directors' compensation or be an affiliated person of ours or any of our subsidiaries.

Each year, our directors are obligated to complete a questionnaire that requires them to disclose any transactions with us in which the director or any member of such director's immediate family might have a direct or potential conflict of interest. We also conduct internal diligence on our businesses related to transactions, relationships or arrangements between Leidos and our directors. Based on its review of an analysis of this information, the Board determined that Mr. Dahlberg, Mr. Fubini, Ms. Geer, Dr. John, Mr. Kovarik, Mr. Kraemer, Dr. May, Dr. Mohapatra, Mr. Shanahan, Mr. Shapard and Ms. Stalnecker are independent under its guidelines and free from any relationship that would interfere with the exercise of their independent judgment. Mr. Krone was not deemed independent because of his role as our Chief Executive Officer until May 2, 2023. Mr. Bell, a nominee to our Board, has also not been deemed independent because of his upcoming role as our Chief Executive Officer, effective May 3, 2023.

PROPOSAL 1: ELECTION OF DIRECTORS

**Director Nomination Process**

The Corporate Governance and Ethics Committee utilizes a variety of methods for identifying and evaluating nominees for director. The Committee regularly assesses the Board's current and projected strengths and needs by, among other things, reviewing the Board's current profile, the criteria for board membership described in this proxy under the caption "Corporate Governance—Criteria for Board Membership," and our current and future needs.

Each nominee is a current Board member who was elected by stockholders at the 2022 annual meeting of stockholders, other than Mr. Bell, our incoming CEO, who the Board has nominated for election by our stockholders at the 2023 annual meeting of stockholders.

**Stockholder Recommendations and Nominations of Director Candidates**

The Corporate Governance and Ethics Committee considers stockholder recommendations for candidates for the Board of Directors using the same criteria described above under "Corporate Governance — Criteria for Board Membership." The name of any recommended candidate for director, together with a brief biography, a document indicating the candidate's willingness to serve if elected, and a description of any ownership of shares of our common stock must be sent to: Leidos Holdings, Inc., Office of the Corporate Secretary, 1750 Presidents Street, Reston, Virginia 20190. Any stockholder nominating a person for election as a director must comply with the procedures set forth in our bylaws.

Corporate Governance

**Corporate Governance Highlights**

Leidos recognizes the importance of strong corporate governance to address the interests of our stockholders, employees, customers, supplier partners and other stakeholders. We believe that strong corporate governance is critical to achieving our mission and long-term stockholder value. The following table highlights certain of our corporate governance practices and policies:

▶Independent Chair following the 2023 annual meeting with robust and well-defined responsibilities

▶Executive session during every Board meeting led by the Independent Chair following the 2023 annual meeting without management present

▶No supermajority stockholder voting requirements in our charter or bylaws

▶Proxy access right for stockholders

▶Annual election of all directors

▶Majority voting with resignation policy for directors in uncontested elections

▶Annual Board and Committee evaluations, periodic, third-party facilitated evaluations

▶Risk oversight by Board and Committees

▶Independent directors focus on executive succession planning

▶Independent Committee chairs

▶Annual advisory vote on executive compensation

▶Meaningful stock ownership requirements for directors and executives

▶Robust board refreshment process, including a focus on skills, diversity and ethics

▶Annual review of Committee charters and Corporate Governance Guidelines

After the 2023 annual meeting of stockholders, the Board expects to split the roles of CEO and Chair, and appoint Mr. Shapard as the independent, non-executive Chair of the Board. Our Board believes that this leadership structure is appropriate at this time because it will effectively and efficiently allocate authority, responsibility, and oversight between management and independent members of our Board.

**Corporate Governance Guidelines**

Our Board recognizes the importance of strong corporate governance to address the interests of our stockholders, employees, customers, supplier partners and other stakeholders. Our Board has adopted Corporate Governance Guidelines which, together with our certificate of incorporation, bylaws, committee charters and other key governance practices and policies, provide the framework for our corporate governance. Our Corporate Governance Guidelines cover a wide range of subjects, including criteria for determining the independence and qualification of our directors. These guidelines are available on our website at www.leidos.com by clicking on the links entitled "Investors" followed by "Corporate Governance." In addition, the Board recognizes that observing good corporate governance practices is an ongoing responsibility. The Corporate Governance and Ethics Committee regularly reviews corporate governance developments and recommends revisions to these Corporate Governance Guidelines and other corporate governance documents as necessary to promote our stockholders' best interests and to support our compliance with all applicable laws, regulations and stock exchange requirements.

**Board and Committee Structure**

**BOARD LEADERSHIP STRUCTURE**

The Board is currently led by Roger A. Krone as Chair and Chief Executive Officer and Robert S. Shapard as Independent Lead Director. After the 2023 annual meeting of stockholders, the Board expects to split the roles of CEO and Chair, and appoint Mr. Shapard as the independent, non-executive Chair of the Board. Our Board believes that this anticipated leadership structure is appropriate at this time because it will effectively and efficiently allocate authority, responsibility, and

oversight between management and independent members of our Board and support the independence of our non-management directors.

Our Board believes that it is in the best interests of stockholders for the Board to have the flexibility to determine the most qualified and appropriate individual to serve as Chair of the Board, whether that person is an independent director or the Chief Executive Officer.

We believe that our Board leadership structure provides for strong independent and effective oversight of our business through Mr. Shapard, our Independent Lead Director (and upcoming Independent Chair), independent Board committee chairs, experienced and committed directors and frequent executive sessions without management in attendance. The Independent Lead Director (and upcoming Independent Chair) also plays a key role in managing risk matters, and, in consultation with the Board, may override the CEO as necessary. Our Board believes that these elements, taken together, provide for objective, independent Board leadership, effective engagement with and oversight of management, and a voice that is independent from management and accountable to stockholders and other stakeholders.

The Board selects the Chair annually and has decided to separate the roles of Chair of the Board and Chief Executive Officer, effective as of the 2023 annual meeting of stockholders. The Board may, if appropriate, change that structure at any time in the future. Maintaining flexibility on this decision allows the Board to choose the leadership structure that will best serve the interests of the Company and its stockholders at any particular time. In cases where the Board determines it is in the best interests of our stockholders to combine the positions of Chair and Chief Executive Officer, the Corporate Governance and Ethics Committee nominates an independent director to serve as "Independent Lead Director," who then must be approved by at least a majority of the independent directors.

Our Board is committed to strong corporate governance and believes that Board independence and oversight of management will be effectively maintained following the 2023 annual meeting of stockholders with the separation of the CEO and Chair roles. The Board's Audit and Finance, Human Resources and Compensation and Corporate Governance and Ethics Committees are each led by and comprised entirely of independent directors.

CORPORATE GOVERNANCE

**BOARD COMMITTEES**

The Board has delegated certain duties to committees, which assist the Board in carrying out its responsibilities. There are four standing committees of the Board. Each independent director serves on at least two committees. The key oversight responsibilities of the committees, the current committee memberships, and the number of meetings held during 2022 are described below.

The Board has adopted charters for each of the Audit and Finance Committee, the Corporate Governance and Ethics Committee, the Human Resources and Compensation Committee, and the Technology and Information Security Committee. The charters of these committees are available on our website at www.leidos.com by clicking on the links entitled "Investor Relations," "Corporate Governance," and then "Board Committees." You may also obtain printed copies of these charters by writing to our Corporate Secretary at the Company's headquarters. From time to time, the Board may also establish ad hoc committees to address particular matters. For example, in November 2021, our Board established a special committee of independent directors to oversee an internal investigation, with the assistance of external legal counsel, related to certain conduct that may have violated the Company's Code of Conduct and potentially applicable laws, including the U.S. Foreign Corrupt Practices Act. This special committee is comprised of Ms. Geer and Messrs. Kovarik and Shapard (Chair), and held 14 meetings in 2022.

Listed below are the members of each of the four standing committees as of the date of this proxy statement:

**DIRECTOR ORIENTATION AND CONTINUING EDUCATION**

Our directors are expected to keep current on issues affecting Leidos and our industry and on developments with respect to their general responsibilities as directors. In addition, the Board encourages directors to participate annually in continuing director education programs, and the Company reimburses directors for their expenses associated with this participation. Continuing director education is also provided during Board meetings and other Board discussions and as stand-alone information sessions outside of meetings. We also conduct orientation programs to familiarize new directors with our businesses, strategies, and policies and assist new directors in developing Leidos and industry knowledge to optimize their service on the Board. Directors have access to additional orientation and educational opportunities upon acceptance of new or additional responsibilities on the Board and in committees.

**ANNUAL BOARD AND COMMITTEE EVALUATION PROCESS**

The Board believes that establishing and maintaining a robust evaluation process is essential to maintaining Board effectiveness and best corporate governance practices. Accordingly, the Corporate Governance and Ethics Committee annually evaluates the performance of the Board and its committees.

CORPORATE GOVERNANCE

**Transparency and Accountability**

The Board believes that transparency and accountability are a critical part of our ESG strategy. Leidos publishes reports annually in accordance with the latest GRI™ Sustainability Reporting Standards and strives for continuous improvement, alignment with industry best practices and leadership in corporate sustainability and responsibility. The Company periodically re-evaluates and updates its sustainability and corporate responsibility programs and how it shares progress with stakeholders.

▶In 2019, Leidos produced its first Sustainability Accounting Standards Board (SASB) Disclosure Supplement.

▶In 2021, Leidos partnered with outside experts to conduct a formal ESG assessment, including a stakeholder engagement initiative. This engagement, alongside an analysis of internal and external trends and aligned with business priorities, helped us develop our "Next Level Leidos" ESG Goals. The goals will form the basis of the Company's Sustainability Management Plan and drive progress in priority areas.

▶In 2022, Leidos released its 13th Annual Report covering the calendar year 2021, integrating its GRI™ Index and SASB Standards into one document to provide a comprehensive view of corporate practices in this area.

▶Leidos publishes its annual EEO-1 report, which includes information regarding its workforce diversity.

We provide additional information regarding our ESG goals on our corporate website at https://www.leidos.com/company/responsibility-and-sustainability/esg-goals. The reports mentioned above, or any other information from our website, are not part of, or incorporated by reference into this proxy statement. Some of the statements and reports contain cautionary statements regarding forward-looking information that should be carefully considered. Our statements and reports about our objectives may include statistics or metrics that are estimates, make assumptions based on developing standards that may change, and provide aspirational goals that are not intended to be promises or guarantees. The statements and reports may also change at any time, and we undertake no obligation to update them, except as required by law.

**BOARD'S ROLE IN OVERSIGHT OF SUCCESSION PLANNING**

The Board of Directors believes it is critical to the success of the Company that continuity of leadership is ensured and that a succession plan exists for the Chief Executive Officer and other key officers. The Corporate Governance and Ethics Committee evaluates and makes recommendations to the Board on candidates for the position of Chief Executive Officer in the event that a vacancy arises or is anticipated to arise, through the death, disability, retirement or resignation of the Company's Chief Executive Officer. The Corporate Governance and Ethics Committee is also responsible for ensuring that processes are in place for management development and succession throughout the leadership ranks. The Chief Executive Officer annually provides the Board and/or the Corporate Governance and Ethics Committee with an assessment of other senior managers and their potential to succeed them, as well as an assessment of persons considered potential successors to certain other senior management positions.

The selection and appointment of Thomas A. Bell as the incoming Chief Executive Officer demonstrate the Board's active role in succession planning. As part of a planned succession process, the Board engaged a third-party executive search firm to lead a search for a new CEO. Following interviews and a careful review of qualified candidates presented by the executive search firm, which included diverse candidates, the Board, upon recommendation from the Corporate Governance and Nominating Committee, approved the appointment of Thomas A. Bell as Leidos' new Chief Executive Officer, effective May 3, 2023. Mr. Bell will succeed Roger A. Krone, who will retire as Chairman at the time of the Company's 2023 annual meeting of stockholders, and as Chief Executive Officer as of May 3, 2023. The Board expects to appoint Robert S. Shapard as independent, non-executive Chair after the 2023 annual meeting of stockholders and also nominated Mr. Bell to the Board. To facilitate a seamless leadership transition, Mr. Krone will continue to work as a full-time employee through July 31, 2023. He will then become a part-time advisor to the Company through March 29, 2024.

**Other Governance Policies and Practices**

**CODES OF CONDUCT**

All of our employees, including our executive officers, are required to comply with our Code of Conduct, which describes our standards for protecting company and customer assets, fostering a safe and healthy work environment, dealing fairly with customers and others, conducting international business properly, reporting misconduct and protecting employees from retaliation. This code forms the foundation of our corporate policies and procedures designed to promote ethical behavior in all aspects of our business.

Our directors are required to comply with our Code of Business Conduct of the Board of Directors, which describes areas of ethical risk, provides guidance to directors and helps foster a culture of honesty and accountability. This code addresses areas of professional conduct relating to service on our Board, including conflicts of interest, protection of confidential information, fair dealing and compliance with all applicable laws and regulations.

These documents are available on our website at www.leidos.com by clicking on the links entitled "Investors" followed by "Corporate Governance." We intend to post on our website any material changes to or waivers from our Code of Conduct and Code of Business Conduct of the Board of Directors.

**RELATED PARTY TRANSACTIONS**

**Our Policy and Procedures**

The Board has adopted written policies and procedures for the review and approval of transactions between us and certain "related parties," which are generally considered to be our directors and executive officers, nominees for director, holders of five percent or more of our outstanding capital stock and members of their immediate families. The Board has delegated to the Audit and Finance Committee the authority to review and approve the material terms of any proposed related party transaction. If a proposed related party transaction involves a non-employee director or nominee for election as a director and may be material to a consideration of that person's independence, the matter is also considered by the Chair of the Board and the Chair of the Audit and Finance Committee.

In determining whether to approve or ratify a related party transaction, the Audit and Finance Committee considers, among other factors it deems appropriate, the potential benefits to us, the impact on a director's or nominee's independence or an executive officer's relationship with or service to us, whether the related party transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related party's interest in the transaction. In deciding to approve a transaction, the Committee may, in its sole discretion, impose such conditions as it deems appropriate on the related party or us. Any transactions involving the compensation of executive officers, however, are to be reviewed and approved by the Human Resources and Compensation Committee. If a related party transaction will be ongoing, the Audit and Finance Committee may establish guidelines to be followed in our ongoing dealings with the related party. Thereafter, the Audit and Finance Committee will review and assess ongoing relationships with the related party on at least an annual basis to determine whether they comply with the Committee's guidelines and that the related party transaction remains appropriate.

We engage in transactions and have relationships with many entities, including educational, charitable and professional organizations, in the ordinary course of our business. Some of our directors, executive officers or their immediate family members may be directors, officers, partners, employees or stockholders of these entities. We carry out transactions with these firms on customary terms.

**Director Compensation**

We use a combination of cash and stock-based incentives to attract and retain qualified candidates to serve as directors. In determining director compensation, we consider the significant amount of time required of our directors in fulfilling their duties, as well as the skill and expertise of our directors. FW Cook provides competitive compensation data and director compensation program recommendations to the Human Resources and Compensation Committee for review to assist in determining its recommendation. The competitive compensation data includes information regarding the compensation (cash, equity and other benefits) of the non-employee directors within our compensation peer group that is further described in "Comparable Market Compensation" on page [53](#ifaf8319aa3bc497da1521cf9f4ba62e8_210639). The Human Resources and Compensation Committee considers this information and recommends to the Board the form and amount of compensation to be provided. The director compensation described below represents the total compensation received by our directors for their service as directors for both Leidos Holdings, Inc. and Leidos, Inc. Annual retainer amounts are prorated based on time served on the Board or in a committee chair role during the year. We also reimburse our directors for expenses incurred while attending meetings or otherwise performing services as a director. We do not pay separate meeting fees. Our employee director does not receive additional compensation for service as a director.

The following is a summary of our annual compensation program for our non-employee directors, as paid for service in 2022:

**DEFERRAL PLANS**

Non-employee directors are eligible to defer all or any portion of their cash retainers or certain equity compensation into our Keystaff Deferral Plan or Key Executive Stock Deferral Plan, or both. These plans are described in further detail under the caption "Executive Compensation—Nonqualified Deferred Compensation" below.

**STOCK OWNERSHIP GUIDELINES AND POLICIES**

The Board believes that its members should acquire and hold shares of our stock in an amount that is meaningful and appropriate. To encourage directors to have a material investment in our stock, the Board has adopted stock ownership guidelines that call for directors to hold shares of our stock earned from their service on our Board until attaining stock ownership with a value of at least five times the amount of their annual cash retainer. All of our directors continue to observe this holding requirement. In addition to these ownership guidelines, our directors are also subject to policies that prohibit certain short-term or speculative transactions in our securities that we believe carry a greater risk of liability for insider trading violations or may create an appearance of impropriety. Our policy requires directors to obtain preclearance for all transactions in our securities. In 2022, no directors were granted an exception to these requirements.

<sup>(1)</sup> Ms. Waterston was appointed Executive Vice President, Chief Human Resources Officer, effective March 1, 2022.

In this CD&A, the "Committee" refers to the Human Resources and Compensation Committee of the Board of Directors, which is responsible for overseeing the compensation programs for all of our executives. The tabular disclosures following this CD&A provide data on all of our named executive officers.

Our executive compensation programs are designed to align the interests of senior management with stockholders by tying a significant portion of their potential compensation to the achievement of challenging financial performance goals, which include adjusted operating income, total backlog, free cash flow, revenue and relative total shareholder return. A small portion is also contingent on personal and leadership goals. We believe these factors contribute to a top-tier workplace environment, improve our efficiency and effectiveness, help us to win key business opportunities and ultimately drive

long-term value for stockholders.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**EXECUTIVE SUMMARY**

**BUSINESS PERFORMANCE HIGHLIGHTS FOR 2022 RELATED TO PAY**

Our business performance in 2022 was strong. We ended fiscal 2022 with reported revenues of $14.4 billion, an increase of 5% compared to the prior fiscal year. Our performance validated that our diversified and resilient portfolio and our investments in technology and innovation are positioning us for growth in key customer missions, including digital modernization, cyber, hypersonics, and force protection. Against a challenging backdrop in fiscal 2022, we delivered on our financial commitments to investors, allocated capital to deliver value for our stockholders, won multiple franchise programs that position us for future growth, and significantly grew our talent base.

The information below are the performance metrics that form a significant part of our 2022 compensation targets. We achieved 100% of our total backlog compensation target, giving us a strong foundation for growth. Adjusted operating income reached 98% of compensation target. We also achieved 101% of our free cash flow compensation target, reflecting strong performance across our operational segments. We provide additional information regarding these compensation metrics, including a definition of such metrics and adjustments made for our compensation programs from the reported metrics, in "Annual Cash Incentive Awards for Fiscal 2022" on page 55<sup>(1)(2)</sup>.

<sup>(1)</sup> Amounts shown for fiscal 2022, other than revenue, are adjusted metrics as used in our compensation targets.

<sup>(2)</sup> We use financial measures in this proxy statement that are not measures of financial performance under U.S. generally accepted accounting principles (GAAP), in particular as compensation targets. These non-GAAP measures should be viewed as supplements to (not substitutes for) our results of operations and other measures reported under GAAP. Other companies may not define or calculate these non-GAAP measures in the same way. We provide a reconciliation of non-GAAP measures used as compensation targets in this proxy statement on page [57](#ifaf8319aa3bc497da1521cf9f4ba62e8_212328).

2023 PROXY STATEMENT 45

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**EXECUTIVE COMPENSATION PHILOSOPHY**

We believe that executive pay should be largely variable, equity-based, and tied to preset performance goals, and this is demonstrated in our pay mix and design.

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**LIMITED FIXED COMPENSATION** | &nbsp;&nbsp;**PREDOMINANTLY<br>EQUITY-BASED PAY** | &nbsp;&nbsp;**FOCUS ON PRE-SET FINANCIAL PERFORMANCE GOALS AND STOCK PRICE APPRECIATION** |
| Base salary is the only component of "fixed" compensation for our named executive officers and represents a significantly smaller portion of executive pay than "variable" compensation—representing a range between 10% for our Chief Executive Officer and 28% for the highest non-CEO NEO. | The majority of executive pay takes the form of long-term equity incentives—a mix of performance shares, PRSUs, and stock options-ranging from 49% to 75% of target total direct compensation. This reflects our belief that equity should comprise the largest component of executive pay. | The vast majority of the annual cash incentive—80% of the target opportunity—is tied to preset, quantifiable goals. Similarly, 80% of the target opportunity for long-term incentives are tied to preset goals: 50% in the form of three-year performance share program awards, and 30% in the form of PRSUs. The remaining 20% of the target opportunity for long-term incentives is in the form of stock options, which will not yield value unless the stock price increases from the grant date. |

**Pay Composition**

The chart below depicts each principal element of target compensation as a percentage of total direct compensation for each of our named executive officers for 2022.

![ldos-20230315_g109.jpg](ldos-20230315_g109.jpg)

<sup>(1)</sup> Percentages shown for Ms. Waterston do not include cash sign-on award, equity sign-on award, or relocation expenses, as these are one-time compensation decisions made in connection with her hiring.

**2023 COMPENSATION CHANGES AT A GLANCE**

▶Each year, we perform a comprehensive review of our executive compensation program in consideration of our performance, the performance of our peer group, historical pay information, market practices and trends, the market for talent, stockholder and other stakeholder feedback, and other relevant points of information to assess the program, executive compensation levels and pay design.

▶Beginning in 2023, we have modified the design of our short-term incentive program to reflect new financial performance metrics and weighting, and an increase in the maximum payout scale from 150% to 200%.

▶We have adopted an "Engage" modifier to the personal performance portion of our short-term incentive plan. The modifier, which is being included as part of the "personal goals" portion of our short-term incentive plan, will be measured against the Company's efforts to increase representation of female and ethnically diverse employees (measured against the "Next Level Leidos" goal of a 10% increase by 2030), improve employee retention and engagement metrics, and upskill our technical workforce.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**EXECUTIVE COMPENSATION HIGHLIGHTS**

Our compensation programs seek to closely align the interests of our named executive officers with the interests of our stockholders. To achieve this goal, our programs are designed to:

▶Pay for performance by tying a substantial majority of an executive's compensation to the achievement of financial and other performance measures that the Board believes will promote the creation of long-term stockholder value and will position the company for long-term success;

▶Target total direct compensation at approximately the median among companies with which we compete for executive talent;

▶Enable us to recover, or "clawback," incentive compensation if there is any material restatement of our financial results or if an executive is involved in misconduct;

▶Require our executives to own a significant amount of our stock;

▶Avoid incentives that encourage unnecessary or excessive risk-taking; and

▶Compete effectively for talented executives who will contribute to our long-term success.

The following table summarizes certain highlights of our executive compensation practices and policies:

| The Committee has retained Frederic W. Cook & Co. (FW Cook) as its independent compensation consultant to assist the Committee in evaluating executive compensation programs and in setting executive officer compensation. FW Cook serves the Committee in an advisory role only and does not decide or approve any compensation actions. The consultant reports directly to the Committee and does not perform any services for management. The consultant's duties include the following:<br>▶Reviewing our total compensation philosophy, compensation peer group, and target competitive positioning for reasonableness and appropriateness;<br>▶Reviewing our overall executive compensation program and advising the Committee on evolving best practices;<br>▶Providing independent analyses and recommendations to the Committee on executive officers' compensation and new programs that management submits to the Committee for approval; and<br>▶Reviewing the Compensation Discussion and Analysis for our Proxy Statement.<br>The consultant interacts directly with members of management only on matters under the Committee's oversight and with the knowledge and permission of the Committee. The Committee has assessed the independence of FW Cook pursuant to applicable SEC and NYSE listing rules and concluded that the firm's work for the Committee does not raise any conflict of interest. | The role of the Committee is to have direct responsibility relating to the following:<br>▶Executive compensation;<br>▶Evaluation and approval of compensation plans, policies and programs, including incentive compensation and equity-based plans for employees and officers;<br>▶Preparation of reports on executive compensation for inclusion in the Company's proxy statement or Annual Report on Form 10-K;<br>▶Reviewing and making recommendations to the Board of Directors regarding director compensation; and<br>▶Ensuring that the Company's human resources policies and practices are consistent with the Company's values and long term objectives. | The CEO presents the Committee with performance assessments and compensation recommendations for each NEO, other than himself.

**How We Determine Total Direct Compensation**

---

| | |
|:---|:---|
| **Establishing <br>Criteria** | In determining the amounts of total direct compensation (base salary, annual and long-term incentives) to be awarded to our NEOs, we considered the:<br>▶Company's overall performance;<br>▶Performance of operating units under the NEO's management;<br>▶Individual performance as measured against performance goals and criteria; and<br>▶Competitive market data for our compensation peer group as well as third-party survey data for the general industry and the technology industry. |
| **Review of Criteria** | **Company and Operational Group Performance**<br>Our overall enterprise performance (or a combination of company enterprise and business group performance for NEOs with operational responsibilities) determines the payout for 80% of the target amount of any annual cash incentive awards and for 100% of any PSAs and PRSUs. Payout amounts are principally determined based upon the Company's or group's achievement of financial and operating objectives set at the beginning of the fiscal year, but the Committee retains the discretion to reduce the payouts when appropriate. The maximum score for performance on any of the financial metrics for the cash incentive awards and the performance share program awards is 150%. The earnings per share metric for the PRSUs is a hurdle that, when met, results only in continued time-vesting of the PRSUs; results for this metric do not result in an adjustment to the amount of the PRSUs.<br>**Individual Performance**<br>Individual performance is a factor in setting base salaries, and individual leadership behaviors and the achievement of personal goals determine 20% of the target amount of any annual cash incentive award to be paid upon completion of the fiscal year for all of our NEOs. In determining base salaries, the Committee reviews a performance assessment for each of our NEOs, as well as compensation recommendations provided by the Chief Executive Officer for the other NEOs.<br>The Committee also considers market data and information provided by FW Cook. In addition, in determining annual incentive amounts, the Committee considers whether the NEO has achieved predetermined personal goals applicable to their organization, and the way in which those personal goals were achieved, as demonstrated through leadership behaviors.<br>Personal performance goals and leadership behaviors relate to ethics and integrity, maintaining a top-tier workplace environment, collaboration, customer satisfaction and retention, business development in strategic areas and other financial and operating goals as appropriate. For purposes of the 2022 annual cash incentive, personal performance is scored on a range from 0% to 150% with a threshold of 50%. Performance below threshold with respect to personal goals would result in no payout (0%) related to the portion of the cash incentive based on personal performance. Performance of between 50% and 150% with respect to these goals for 2022 would result in a payout that is interpolated linearly between the 50% and 150% payout opportunity. Performance above the 150% level would not result in any additional payout. |

| | **Assessing Chief Executive Officer Performance**<br>In determining compensation for our Chief Executive Officer, the Committee meets in executive session and evaluates his performance based on his achievement of performance objectives that were established and agreed upon at the beginning of the fiscal year. Input is received from the independent directors. The Committee also considers the Chief Executive Officer's general leadership contributions towards the Company's performance, including financial and operating results, development and achievement of strategic objectives, progress in building capability among the senior management team and leadership in ESG. The Committee also considers market data and information provided by FW Cook. The Committee determines the Chief Executive Officer's compensation and then reviews his evaluation and compensation with the Board's independent directors. The Independent Lead Director and the Chair of the Committee then present the Committee's evaluation and compensation determination to the Chief Executive Officer<br>At the beginning of each fiscal year, the Committee reviews and approves:<br>▶The amount of base salary and target incentive opportunities to be provided for the upcoming year;<br>▶The payout range for the annual cash incentive awards that may be earned for the year and the performance goals and criteria upon which the amounts of the awards will be determined;<br>▶The payout range for PSAs that may be earned for the performance period beginning in that fiscal year and the performance goals and criteria upon which the amounts of the PSAs and PRSU awards for the relevant performance period will be determined; and<br>▶The mix and amount of long-term incentive awards (including PSAs, PRSUs and stock options) to be granted to our NEOs. |
| **Approval of Awards** | The Committee reviews and approves the amount of direct compensation to be provided to our NEOs for each fiscal year. NEOs do not propose their own compensation.<br>In approving payout ranges for our incentive programs, we determine the levels of performance that must be achieved in order to receive a threshold, target and maximum payout amount for each goal. Upon completion of each fiscal year, the Committee approves the payment, if any, of cash incentive awards and the number of performance shares, if any, that are earned based upon the achievement of the predetermined performance goals and criteria for the performance cycles just completed. |

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**COMPARABLE MARKET COMPENSATION**

The Committee compares the amount of direct compensation that we provide to our NEOs to that provided by companies with whom we compete for executive talent in similar roles and with similar responsibilities. To assist with this effort, FW Cook conducts an annual review and benchmarking analysis of each element of target total direct compensation (including salary, cash and equity incentives) provided to our executive officers. In October 2021, FW Cook compared the target compensation provided to members of senior management against that provided by other publicly traded engineering, information technology, consulting and defense companies, which we refer to as our "compensation peer group," as well as third-party survey data for the general industry and the technology industry.

Compensation peer group companies are chosen for having a similar industry focus as ours and for competing with us for talent, as well as for business and stockholder investment. Furthermore, the compensation peer group is initially structured so that no company within the group has annual revenues smaller than 40% or greater than 250% of our annual revenue and a market capitalization within a reasonable range.

The Committee periodically reviews and updates the compensation peer group to ensure that the companies in our compensation peer group are strong business and talent competitors and are comparable in size. In July 2021, the Committee consulted with FW Cook and reviewed the compensation peer group to be used for setting fiscal 2022 target compensation. Based on the criteria discussed above, the Committee decided to add KBR to the compensation peer group. KBR met the appropriate size criteria, was identified by management as a talent and business competitor, is used as a peer in proxy advisory firm's peer groups for Leidos, is prevalent in the "Peers of Peers" analysis (i.e., benchmarked by six of Leidos' current peers), uses Leidos as a peer, and uses six of Leidos' current peers in its peer group. At the time the compensation peer group for fiscal 2022 was approved, the Company was at the 59th percentile for revenue and the 51st percentile for market capitalization as compared to the new compensation peer group.

The Committee considers market data and analysis when evaluating appropriate levels of target total direct compensation. To be competitive in the market for our executive-level talent, we generally:

▶Target overall compensation for our NEOs at the market median, although the actual cash paid and equity incentive awards earned will vary based on actual financial and individual performance and may therefore generate compensation that is higher or lower than the market median; and

▶Award higher levels of compensation, when appropriate, in recognition of the importance or uniqueness of the role of an executive officer or to address retention concerns.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**STOCKHOLDER ADVISORY VOTE**

At our last annual stockholders' meeting in April 2022, we held a non-binding stockholder advisory vote on the compensation of our named executive officers, commonly referred to as a say-on-pay vote. Our stockholders overwhelmingly approved the compensation of our named executive officers, with approximately 96% of stockholder votes cast in favor of our say-on-pay resolution.

---

| | |
|:---|:---|
| **2022 SAY-ON-PAY**<br>As we evaluated our compensation practices during fiscal 2021, we considered the support our stockholders expressed for our pay for performance compensation philosophy and that influenced our decision not to make any significant changes to our executive compensation programs this year. We continued to emphasize short- and long-term incentive compensation, targeted at competitive market median levels, with a substantial majority of total compensation based on the achievement of financial performance goals designed to deliver value for our stockholders. | &nbsp;&nbsp;![ldos-20230315_g110.jpg](ldos-20230315_g110.jpg) |

---

At our 2017 annual meeting of stockholders, our stockholders expressed a preference for an annual, non-binding advisory vote on executive compensation, in accordance with our Board's recommendation. Consistent with our stockholders' preference in this regard, we expect to continue holding an advisory stockholder vote on the compensation of our named executive officers each year. We have included our proposal to continue an annual non-binding advisory vote in our Proposal 3 - Advisory Vote on Frequency of Vote on Executive Compensation. The vote will occur at the 2023 annual stockholder meeting.

**ASSESSMENT OF RISKS IN OUR COMPENSATION PROGRAMS**

During fiscal 2022, management undertook a risk assessment of our compensation programs, which FW Cook reviewed. In conducting the assessment, we reviewed our pay practices and incentive programs to identify any potential risks inherent in our compensation programs. We also reviewed the risks facing the company and evaluated whether our compensation practices and programs could be expected to increase or help mitigate these risks. The finding of the assessment, with which the Committee concurred, was that our compensation programs are effectively designed to help mitigate excessive risk-taking that could harm our value or inadvertently reward poor judgment by our executives or other employees. The factors considered in reaching this conclusion include:

▶Short-term incentive measures that are balanced among different financial measures, with targets that are intended to be achievable upon realistic levels of performance;

▶Significant weighting toward long-term incentive compensation that promotes long-term decision-making and discourages short-term risk-taking;

▶Maximum payouts that are capped at levels that do not reward excessive risk-taking;

▶Goals that are based on company and group performance measures, which mitigates excessive risk-taking within any particular business unit;

▶Leadership behaviors, such as ethics and integrity, that are specifically addressed in our short-term incentive programs;

▶Our compensation recoupment policy that allows us to recover compensation based on financial results that are subsequently restated or if fraud or intentional misconduct is involved; and

▶Our stock ownership guidelines that encourage a long-term perspective.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**COMPENSATION DECISIONS FOR FISCAL 2022**

**BASE SALARY**

The Committee reviews executive officers' base salaries annually or at the time of promotion or a substantial change in responsibilities based on the criteria described above. For fiscal 2022, the Committee considered FW Cook's analysis of salary levels for comparable positions in the compensation peer group based on proxy and survey data. Individual base salary amounts also reflect the Committee's judgment with respect to each executive officer's level of responsibility, individual performance, experience and other factors, including internal equity considerations, the individual's historical compensation and any retention concerns.

At the beginning of 2022, the Committee approved increases in the base salaries for our named executive officers in order to bring them closer to the market median of our compensation peer group.

**ANNUAL CASH INCENTIVE AWARDS FOR FISCAL 2022**

Payout under the fiscal 2022 annual cash program is based primarily on financial results against our metrics (80%) with an additional (20%) on the achievement of personal performance goals. The financial metrics are further weighted as follows: Adjusted Operating Income of "AOI" (40%), Total Backlog (40%) and Free Cash Flow (20%).

| | |
|:---|:---|
| Performance Measures and Weightings. Our annual cash incentive plan for fiscal 2022 was designed to incentivize and reward both Company financial performance and individual contributions to enterprise goals. The intended purpose and relative weightings of the performance goals are shown below: | **Total Backlog** measures our success at winning contracts - both contracts for which funding has been appropriated (less revenues previously recognized) and contracts where we can estimate the amount of future revenues.<br>**Free Cash Flow** represents cash flow generated from the ongoing operations of the business, less capital expenditures. It represents capital that can be deployed to support the growth of the business, repay debt, or return capital to shareholders. |
| ![ldos-20230315_g111.jpg](ldos-20230315_g111.jpg) | **Adjusted Operating Income** measures growth and core operating performance and is strongly correlated with potential stockholder value.<br>AOI is operating income adjusted for non-recurring or discrete items that do not reflect core operating performance, such as net non-operating expenses, restructuring costs, and non-cash accounting charges.<br>If we fail to achieve at least 70% of our adjusted operating income goal, there is no payout to executives for any of the 80% portion of the bonus pool represented by financial goals.<br>**Personal Goals** are based on integrity, inclusion, innovation, agility, collaboration, and a commitment to our customers and our team, which we believe contributes to financial performance. |

---

Financial Performance Targets. Because our financial results are considered the most important factors in setting pay and are objectively measurable, we weigh these metrics most heavily; financial goals represent 80% of the target opportunity under our annual cash incentive program. To the extent that performance for a financial metric is less than 80% of target (threshold performance) no bonus amount would be paid with respect to that metric. Maximum payout (150% of target) for each component is provided for performance at or above 125% of target. The Committee generally seeks to set financial performance goals for the annual cash incentive program at levels that reflect improvement over the prior year's results. For 2022, the Committee established and approved goals that generally targeted improvement over 2021 results. The free cash flow target reflects an increase in capital expenditures and working capital usage in support of new program awards, coupled with a reduction in customer advance payments on certain programs. In addition, the adjusted operating income target reflects positive impacts of COVID-19 on portions of the company's business in fiscal year 2021.

---

| | | | |
|:---|:---|:---|:---|
| **($ in millions)** | **2021 Results** | **2022 Target** | **% Change** |
| Total Backlog | $34455 | $35300 | 2.45% |
| Adjusted Operating Income | $1409 | $1400 | (0.64)% |
| Free Cash Flow | $927 | $850 | (8.31)% |

---

Personal Goals. We believe that individual contributions towards other enterprise goals are responsible for the achievement of our financial goals over time. Accordingly, non-formulaic personal goals represent 20% of the target opportunity under our annual cash incentive program, in order to encourage individual efforts in an array of areas that we believe will ultimately lead to improved financial performance for the company.

Award Payout Ranges. Payout opportunities for our named executive officers for fiscal 2022 ranged from 80% to 150% of base salary rates. Potential for each financial goal ranged from 60% at threshold performance (paid only when at least 80% of the objective is achieved) to 150% at maximum performance (paid when 125% or more of the objective is achieved), with the payout for performance between these levels interpolated on a straight-line basis. In addition, failure to achieve threshold performance of at least 70% of our annual adjusted operating income goal for the fiscal year would result in no payout for the financial goals portion of the annual cash incentive.

<sup>(1)</sup> Total backlog represents the estimated amount of future revenues to be recognized under negotiated contracts. Backlog value is based on management's estimates about volume of services, availability of customer funding and other factors, and excludes contracts that are under protest. Our estimate of backlog comprises both funded and unfunded backlog. Backlog estimates are subject to change and may be affected by several factors including modification of contracts, non-exercise of options and foreign currency movements. For purposes of our compensation program, we exclude backlog from acquired companies. A reconciliation of total backlog as used in our compensation program to our reported total backlog is set forth below:

<sup>(2)</sup> Free cash flow is defined as operating cash flow less capital expenditures under U.S. GAAP. For purposes of our compensation program, we exclude free cash flow from acquired companies.

<sup>(3)</sup> Adjusted operating income is not a measure of financial performance under generally accepted accounting principles (GAAP) in the United States. We believe that adjusted operating income provides useful information to management and stockholders as it provides another measure of the Company's profitability after adjusting for the impact of discrete events. For purposes of our compensation program, Adjusted Operating Income is defined as GAAP Operating Income (Loss) from continuing operations, adjusted to exclude the impact of amortization of acquired intangible assets (i.e., amortization of the fair value of the acquired equity method investment), acquisition, integration and restructuring costs (integration, lease termination, and severance costs related to the Company's acquisitions), gain (loss) on sale of business (i.e., the net gain on sale of business), asset impairment charges (i.e., impairments of long-lived tangible assets), and operating income from acquired entities.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**Personal Performance Results**

In analyzing personal performance results, the Committee reviewed each individual's level of achievement and also considered input from the Chief Executive Officer — or the independent directors with respect to the Chief Executive Officer's performance. Any circumstance considered relevant by Committee members — or by the independent directors, or in the case of named executive officers other than the CEO, by the CEO — can be a factor in the determination, including the degree of success, the difficulty of achieving personal performance goals and their leadership behavior. For each of the strategic objectives below, goals are established each year. The annual update process starts by evaluating the metric set to ensure it fairly represents enterprise performance objectives. Metrics are added or modified to reflect changing enterprise goals and objectives. Once the metric set is established, we develop a time-phased performance baseline for each metric. Lastly, a scoring methodology and performance thresholds are developed for each metric.

**Total Executive Payouts**

The chart below provides the target annual cash incentive amounts established for each named executive officer by the Committee at the beginning of the year, as well as their actual payout amounts determined by the Committee at the end of the year. Because we surpassed the adjusted operating income goal threshold of 70% of target by achieving 98%, the Committee approved the payout of awards under the annual incentive plan. Actual payout amounts for fiscal 2022 ranged between 99% and 102% of target. Information on all of the annual cash incentive payouts for fiscal 2022 is provided below:

<sup>(1)</sup> In connection with her appointment as Executive Vice President, Chief Human Resources Officer, Ms. Waterston received a target short-term cash incentive valued at $440,000 for the remainder of fiscal 2022 (not subject to proration), with the actual payout determined by the Committee based on the achievement of the performance criteria set forth in the Company's short-term cash incentive program for fiscal 2022.

**LONG-TERM INCENTIVE AWARD GRANTS IN 2022**

Long-term incentive awards are granted to motivate future performance, create long-term alignment with stockholders, and for retention purposes. For fiscal 2022, each named executive officer received a mix of long-term incentive awards comprised of PSAs (50%), PRSUs (30%) and stock options (20%). The grant date fair value of each award was determined based on market data and consideration of each executive officer's level of experience, position and responsibilities. We do not generally consider an executive officer's current stock holdings or outstanding awards in making annual grants.

---

| | |
|:---|:---|
| ![ldos-20230315_g122.jpg](ldos-20230315_g122.jpg) | **Performance Share Awards.** For all of our named executive officers, 50% of the targeted total value of long-term incentive awards granted was in the form of three-year PSAs. Shares are issued under those awards at the end of the three-year performance period (from fiscal 2022 through fiscal 2024 for awards granted in fiscal 2022) only to the extent that the company achieves two specific three-year financial performance goals:<br>▶50% of the award is tied to the achievement of relative total stockholder return goals, a measurement of growth in stockholder value; and<br>▶50% of the award is tied to achievement of revenue goals.<br>Performance for each of these goals is measured on a cumulative basis over the total performance period rather than annually for each year of the performance period. PSAs strengthen the alignment between the compensation of our named executive officers and Company's performance by linking the ultimate payout to pre-established absolute and relative performance goals. |
| Performance Restricted Stock Units. PRSUs comprise 30% of the targeted total value of long-term incentive awards granted to our named executive officers. PRSUs vest 25% each year on the anniversary of the grant date, but are forfeited if we fail to achieve a pre-established performance goal for the first year. The performance goal for fiscal 2022 was adjusted earnings per share of at least $3.24. The Committee determined that this goal was met and therefore the PRSUs granted in fiscal 2022 will be eligible to vest over four years (with such time-vesting to have begun on the date that the PRSU was granted). | Stock Options. The final 20% of targeted total long-term incentive award value granted to our named executive officers is in stock options. Stock options are an effective means of linking rewards to the creation of stockholder value over a longer term. We believe that stock options motivate our executives to build stockholder value because they may realize value only if our stock appreciates during the option term. The options vest 25% each year on each of the first four anniversaries of the grant date and expire on the seventh anniversary of the grant date. |

*Sign-On Awards.* In March 2022, Ms. Waterston received a long-term equity incentive award of restricted stock units with a grant date fair value of $1 million, vesting on the first anniversary of the grant date.

**Performance Equity Vesting in 2022**

***Determination of Performance Shares Earned for the 2020–2022 Performance Period.*** In February 2020, the Committee established long-term performance goals for the performance share program measuring the three-year performance period covering fiscal years 2020 through 2022. The vesting and payout for these performance shares were contingent on the achievement of a relative total shareholder return metric (weighted 50%) and a revenue goal (weighted 50%), with all metrics measuring cumulative results over the three-year performance period.

At its February 2023 meeting, the Committee approved a payout score of 88.35% for the 2020 through 2022 performance period. The tables below show the relative total shareholder return and revenue goals at target, and the actual results for the three-year performance period:

<sup>(1)</sup> Our relative TSR score reflects the aggregate change in the 20-day average closing price of our stock compared to the median of our compensation peer group, as measured at the beginning and end of the three-year performance period, taking into account the value returned to stockholders in the form of dividends, assumed to be reinvested on the distribution date on a pre-tax basis. Our total stockholder return during the three-year period from 2020 to 2022 was 9%, compared to 28% for the median of our compensation peer group, resulting in a payout factor of 81.5%.

<sup>(2)</sup> Revenue of $40.4 billion was reported in the Company's Form 10-Ks for the 3-year period. $40.2 billion is the adjusted compensation target. For purposes of our compensation program, we exclude revenues from acquired companies. A reconciliation of revenue as used in our compensation program to our reported revenue is set forth below:

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**SIGN-ON AWARDS AND COMPENSATION PACKAGE**

As part of her appointment as Executive Vice President, Chief Human Resources Officer, Ms. Waterston received:

▶Base salary of $550,000 annually;

▶Target short-term cash incentive compensation level of $440,000 for the remainder of fiscal 2022 (not subject to proration), with the actual payout determined by the Committee based on the achievement of the performance criteria set forth in the short-term cash incentive program for the fiscal year approved by the Committee;

▶Long-term equity incentive awards having an aggregate grant date fair value of $962,500 to be comprised approximately of 50% three-year cliff vesting PSUs, 30% four-year annual vesting PRSUs, and 20% four-year annual vesting stock options;

▶One-time sign-on award consisting of: (i) $200,000 payable in cash upon commencement of employment; and (ii) a grant of RSUs with a grant date fair value of $1 million, vesting on the first anniversary of the grant date;

▶Payment or reimbursement of amounts not to exceed $250,000 in the aggregate for relocation costs pursuant to the Company's standard relocation policy;

▶Eighty hours of paid time balance at hire; and

▶Other benefits made available by the Company to executive officers generally.

**Other Compensation**

**Other Benefits**

In addition to the elements of direct compensation described above, we also provide our executive officers with the following benefits:

**Health and Welfare Benefits**

Our NEOs are entitled to participate in all health and welfare plans that we generally offer to all of our eligible employees, which provide medical, dental, health, group term life insurance and disability benefits. In addition, our NEOs can elect to participate in a comprehensive voluntary annual health screening program. We believe that these health and welfare benefits are reasonable in scope and amount and are of the kind typically offered by other companies against which we compete for executive talent. For 2022, Mr. Cage, Ms. Waterston, Mr. Howe, and Mr. Fasano waived participation in the health screening program.

**Retirement and Financial Advisory Benefits**

Our NEOs are entitled to participate in the same tax-qualified defined contribution retirement plan that is generally available to all of our eligible employees, subject to certain limits on the amounts that each participant may contribute each year. We make matching contributions to eligible participants' retirement plan accounts based on a percentage of their "eligible compensation" under applicable rules. We believe that this retirement program assists our NEOs in saving for their retirement in a tax-effective manner. We also provide financial advisory services to our NEOs. Ms. Waterston and Mr. Fasano waived participation in the financial advisory services program.

**Deferred Compensation Plans**

To provide other tax-deferred means to save for retirement, we maintain certain deferred compensation plans that allow our named executive officers and other eligible participants to elect to defer all or a portion of any cash or certain equity incentive awards granted to them under our cash incentive or stock plans. In addition, we maintain a deferred compensation plan that allows our named executive officers and other eligible participants to elect to defer a portion of their eligible salary. The deferred balances under the plans are fully vested and will be paid upon retirement or termination or are held in specified date accounts, which pay out in the year specified by the participant, including years prior to termination. These plans are described in more detail under "[Nonqualified Deferred Compensation](#i19013f99d266455da86f7ac367fee52c_152382)."

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**Post-Employment Benefits**

We do not maintain a defined benefit or other supplemental retirement plan that would entitle our executive officers to receive company-funded payments if they leave the company.

Upon certain terminations of employment, including death, disability, retirement or a change in control, our named executive officers may be eligible for continued vesting of equity awards on the normal schedule or accelerated vesting in full or on a pro-rata basis, depending on the nature of the event and the type of award. The purpose of these provisions is to recognize the named executive officer's service through the specified event, and, in the case of acceleration, the named executive officer's loss of an opportunity to continue serving the company through the vesting period. Because these termination provisions are contained in our standard award agreements for all recipients and relate to previously granted or earned awards, we do not consider these potential termination benefits as a separate item in compensation decisions for our named executive officers. Our long-term incentive plans do not provide for additional benefits or tax gross-ups. For more information about potential post-employment benefits, see "[Executive Compensation—Potential Payments Upon Termination or a Change in Control.](#i19013f99d266455da86f7ac367fee52c_152383)"

**Potential Change in Control and Severance Benefits**

We have adopted a severance plan that would provide our named executive officers with payments and benefits if their employment is involuntarily terminated by the company or is terminated following the acquisition of our company. These severance benefits are further described in this Proxy Statement under "[Executive Compensation—Potential Payments Upon Termination or a Change in Cont](#i19013f99d266455da86f7ac367fee52c_152383)[ro](#i19013f99d266455da86f7ac367fee52c_152383)[l](#i19013f99d266455da86f7ac367fee52c_152383)[.](#i19013f99d266455da86f7ac367fee52c_152383)" We believe that our severance plan provides an important benefit to us by helping alleviate any concern that the executive officers might have when contemplating a potential change in control of our company and permitting them to focus their attention on our business. In addition, we believe that this plan is an important recruiting and retention tool, as many of the companies with which we compete for talent have similar arrangements in place for their senior management.

Our named executive officers, other than Mr. Krone, do not have any employment agreements with us. Mr. Krone's employment agreement provides that if his employment is terminated by us for reasons other than cause or by Mr. Krone for good reason, he would receive an amount equal to one times the sum of his base salary and target bonus. Such payment will be subject to Mr. Krone's agreement to release us from any claims. However, if such termination is within three months prior to a change in control or within 24 months after a change in control, Mr. Krone would receive an amount equal to a maximum of two and one half times the sum of his base salary and target bonus and payment for certain benefits, depending on whether the termination occurs during a change in control period. The Committee approved these severance benefits after considering the potential costs, as an inducement for Mr. Krone to join the company.

We have described the change in control and other termination benefits offered to Mr. Krone and our other named executive officers in the section entitled "[Executive Compensation—Potential Payments Upon Termination or a Change in Control](#i19013f99d266455da86f7ac367fee52c_152383)" in the tables following this CD&A.

**OTHER POLICIES AND CONSIDERATIONS**

**EQUITY AWARD GRANT PRACTICES**

The Committee is responsible for the administration of our equity incentive programs pursuant to our 2017 Omnibus Incentive Plan in which our named executive officers participate. The Committee set the equity award fiscal 2022 grant dates for new and existing employees, including executive officers, in October 2021. These grant dates were selected to occur after the dates when we anticipate releasing our annual and quarterly financial results. We generally grant equity incentive awards to our executive officers and all other eligible employees on an annual basis shortly after we announce our financial results for the recently completed fiscal year. In addition to these annual grants, the Committee set three quarterly dates on which any additional equity incentive awards could be made to eligible executive officers or other employees in connection with a new hire, a promotion, for retention or otherwise.

The Committee approves all equity awards made to our directors and executive officers. The exercise price of any option grant is determined by reference to the fair market value of the shares on the grant date, which the 2017 Omnibus Incentive Plan defines as the closing sales price of our common stock on the NYSE on the previous trading day.

**STOCK OWNERSHIP GUIDELINES**

We require our named executive officers to own significant amounts of our stock so that they are motivated to maximize our long-term performance and stock value. Under our established stock ownership guidelines, our named executive officers are required to accumulate and maintain stock holdings in the following amounts:

---

Because they must hold all after-tax shares acquired under our equity incentive programs until they meet this ownership requirement, which we expect will take several years, we do not have specific time-based holding periods following the exercise of stock options or vesting of other equity awards.

In 2022, no executive officers were granted an exception to our stock ownership requirement.

**POLICY ON HEDGING AND SHORT-TERM OR SPECULATIVE TRANSACTIONS**

We have established policies applicable to all designated insiders under our Insider Trading Policy, including all of our directors and named executive officers, that prohibit certain short-term or speculative transactions in our securities. We believe that these prohibited transactions carry a greater risk of liability for insider trading violations and may create an appearance of impropriety. With respect to our securities, our directors, executive officers and other designated insiders are prohibited from engaging in any short sales or any trading in puts, calls or other derivatives on an exchange or other organized market. They are also prohibited from engaging in hedging or other monetization transactions such as cashless collars, forward contracts, equity swaps or similar transactions involving our securities, and from holding company securities in a margin account or pledging securities as collateral for a loan. In addition, our executive officers are required to obtain preclearance for all transactions in our securities.

**COMPENSATION RECOUPMENT POLICY**

Under our compensation recoupment policy, the Committee may require members of senior management including our NEOs to return incentive compensation if there is a material restatement of the financial results upon which the incentive compensation was originally based. Our recoupment policy applies to all incentive compensation, including both cash and equity. If the Committee determines that recovery is appropriate, the company will seek repayment of the difference between the incentive compensation paid and the incentive compensation that would have been paid, if any, based on the restated financial results.

The policy also provides for recovery of incentive compensation from any employee involved in fraud or intentional misconduct, whether or not it results in a restatement of our financial results. In such a situation, the Committee would exercise its business judgment to determine what action it believes is appropriate under the circumstances.

We may seek to recover the applicable amount of compensation from incentive compensation paid or awarded after the adoption of the policy, from future payments of incentive compensation, cancellation of outstanding equity awards and reduction in or cancellation of future equity awards. In cases of fraud or misconduct, we may also seek recovery from incentive

compensation paid or awarded prior to the adoption of the policy. We will revise our policy to comply with the policy requirements of the Securities Exchange Act Rule 10D-1 once the rule is finalized by the New York Stock Exchange.

**TAX DEDUCTIBILITY OF EXECUTIVE COMPENSATION**

Section 162(m) of the Internal Revenue Code, as amended by the Tax Cuts and Jobs Act of 2017, generally limits the deductibility of certain compensation in excess of $1 million paid in any one year to the Chief Executive Officer, the Chief Financial Officer and the three other most highly compensated named executive officers. Prior to the amendment, qualified performance-based compensation was not subject to this deduction limit if certain requirements were met. Under the Tax Cuts and Jobs Act of 2017, the performance-based exception has been repealed. The new rules generally apply to taxable years beginning after December 31, 2017, but do not apply to compensation provided pursuant to a written binding contract in effect on November 2, 2017 that is not modified in any material respect after that date under the American Rescue Plan Act signed into law on March 11, 2021, the applicability of Section 162(m) will be expanded to also include the Company's next five highest paid employees for tax years beginning on or after January 1, 2027.

We do not expect the disallowance of a deduction for compensation paid to our named executive officers in excess of $1 million as a result of these changes to Section 162(m) to significantly alter our compensation programs. The Committee considers it important to design compensation programs that are in the best long-term interests of our company and our stockholders.

**Human Resources and Compensation Committee Report**

The Human Resources and Compensation Committee has reviewed and discussed with our management the CD&A included in this Proxy Statement. Based upon this review and discussion, the Committee recommended to the Board that the CD&A be included in this Proxy Statement.

<sup>(1)</sup> Compensation is provided only for fiscal years for which an individual qualified as a named executive officer in accordance with SEC rules.

<sup>(2)</sup> Ms. Waterston received a one-time sign-on award consisting of $200,000 payable in cash upon commencement of employment.

<sup>(3)</sup> These columns reflect the grant date fair value of each award granted in the stated fiscal years computed in accordance with stock-based compensation accounting rules (FASB ASC Topic 718). The awards shown in the "Stock Awards" column in the above table include restricted stock units and performance share awards. Values for all performance share awards are computed based upon the probable outcome of the performance conditions as of the grant date of the award. Assuming the highest level of the performance conditions is achieved, the value of the fiscal 2022 performance shares in the "Stock Awards" column would be as follows: Mr. Krone, $11,086,291; Mr. Cage, $1,535,145; Ms. Waterston, $2,094,485, Mr. Fasano, $1,387,447; and Mr. Howe, $1,442,865. The awards shown in the "Option Awards" column are not subject to performance conditions.

<sup>(4)</sup> For more information regarding our application of FASB ASC Topic 718, including the assumptions used in the calculation of these amounts, please refer to Note 17 of the Notes to Consolidated Financial Statements contained in our Annual Report on Form 10-K filed with the SEC on February 14, 2023.

<sup>(5)</sup> Amounts shown in this column represent the actual amounts paid to the named executive officers under our cash incentive award programs for the stated fiscal years. The threshold, target and maximum payouts are shown in the "Grants of Plan-Based Awards" table under the column headed "Estimated future payouts under non-equity incentive plan awards."

<sup>(6)</sup> Amounts shown in this column for fiscal 2022 represent company contributions that we made on behalf of the named executive officers under the Leidos Retirement Plan as follows: Mr. Krone, $15,250; Mr. Cage, $15,250; Mr. Fasano, $15,250; and Mr. Howe, $15,250. The column also includes the value of executive financial planning and annual health screenings for Mr. Krone, Mr. Cage, and Mr. Howe. In connection with her appointment as Executive Vice President, Chief Human Resource Officer, Ms. Waterston received a payment or reimbursement of amounts not to exceed $250,000 for relocation costs, in which she received actual reimbursement of $145,431. The Company may also make available unused tickets from sponsorship agreements for personal use. Tickets are included in sponsorship agreements and typically result in no incremental costs to the Company. In 2022, there were no incremental costs associated with the NEO's personal use of tickets to Leidos-sponsored events. All NEOs received upgraded frequent flyer status, at no incremental cost to Leidos, pursuant to arrangements with Leidos' preferred airline vendor.

<sup>(1)</sup> As described in our CD&A, cash incentive awards paid to our named executive officers for performance during fiscal 2022, were based on achievement of pre-established goals. The actual payouts for the fiscal 2022 performance period are provided in the "Summary Compensation Table" in the column headed "Non-Equity Incentive Plan Compensation."

<sup>(2)</sup> The PRSUs in these columns represent restricted stock units which are subject to a performance goal (which, the Committee determined, was met in fiscal 2022) and the following vesting requirement: 25% of the award vests on each of the first, second, third and fourth anniversaries of grant date. The PSAs in these columns represent the threshold, target and maximum number of shares issuable under three-year performance share awards, subject to the Human Resources and Compensation Committee's discretion to decrease the number of shares that are ultimately issued at the end of the three year performance period. The grant date fair value of these awards is provided in the "Summary Compensation Table" in the column headed "Stock Awards."

<sup>(3)</sup> Amounts in this column represent the number of shares of our common stock underlying options issued in fiscal 2022. All options vest 25% on the first, second, third and fourth anniversaries of grant date.

<sup>(4)</sup> The RSUs granted to Ms. Waterston in this column represent a new hire sign-on award which vests in full on the first anniversary of the grant date, subject to her continued employment through the vesting date.

<sup>(5)</sup> The 2017 Omnibus Incentive Plan defines "fair market value" as the closing sales price of our common stock on the NYSE on the trading day before the grant date, and requires the exercise price of options issued under the plan to be at least equal to the fair market value.

<sup>(6)</sup> Amounts represent the grant date fair value determined in accordance with FASB ASC Topic 718. For PRSUs and PSAs, the amount in this column is based on the probable outcome of the performance conditions, excluding the effect of any estimated forfeitures. These amounts do not reflect the value that may actually be realized by the recipient and do not reflect changes in our stock price after the date of grant.

**NONQUALIFIED DEFERRED COMPENSATION**

We provided benefits to our named executive officers during fiscal 2022 under the following nonqualified deferred compensation plans, which are summarized below:

*The Leidos Keystaff Deferral Plan* allows eligible participants to elect to defer all or a portion of salary and any cash bonus granted to them under our cash incentive plan. We make no contributions to participants' accounts under the Keystaff Deferral Plan. Participants can direct their deferrals into investment options similar to those available in the Leidos Retirement Plan other than the Leidos Stock Funds. Distributions under the Keystaff Deferral Plan are then made to participants in cash. Deferred balances under this plan will be paid upon the elected specified date, retirement or separation from service.

*The Leidos Key Executive Stock Deferral Plan* allows eligible participants to elect to defer all or a portion of their cash or certain equity incentive awards granted to them under our cash incentive or stock incentive plans. Participant deferrals in other forms are converted to stock units of our common stock. Participant accounts are credited with additional units corresponding to their outstanding account balance for each company dividend payable. We make no contributions to participants' accounts under the Key Executive Stock Deferral Plan. Distributions under the Key Executive Stock Deferral Plan are then made to participants in shares of common stock corresponding to the number of vested stock units held for the participant. Vested deferred balances under this plan will be paid upon the elected specified date, retirement or separation from service.

*The Leidos 401(k) Excess Deferral Plan (Excess Plan)* is a pre-tax savings plan that, through December 31, 2016, allowed eligible participants to defer up to 20% of their eligible compensation after meeting the annual IRS contribution limit for the Leidos Retirement Plan. Bonuses were not eligible for deferral to the Excess Plan. The investment options in the Excess Plan are similar to those in the Leidos Retirement Plan but do not include the Leidos Stock Funds. Vested deferred balances under this plan will generally be paid following separation from service.

*The Leidos Deferred Compensation Plan for Former IS&GS Employees (Deferred Compensation Plan)* is a pre-tax savings plan that allowed eligible participants to defer salary and receive certain company contributions. Salary deferrals in this plan did not start until after an eligible participant met the annual IRS contribution limit for the Leidos Retirement Plan for Former IS&GS Employees. Bonuses were not eligible for deferral to this plan. The investment options in the Deferred Compensation Plan are similar to those in the Leidos Retirement Plan but do not include the Leidos Stock Funds. Deferred balances under this plan will generally be paid following separation from service.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**POTENTIAL PAYMENTS UPON TERMINATION OR A CHANGE IN CONTROL**

**ROGER A. KRONE, CHIEF EXECUTIVE OFFICER**

Mr. Krone's employment agreement provides severance benefits to him if his employment is terminated by us for reasons other than for cause, or by Mr. Krone for good reason. However, if such termination is within three months prior to or within 24 months after a change in control of the company (the "change in control period"), Mr. Krone would receive a higher level of benefits. In addition, Mr. Krone would be entitled to receive certain benefits and outplacement services in the event of a qualifying termination under his employment agreement. Severance benefits under this agreement in connection with a change in control, or CIC, are "double trigger" and any payments under this agreement are subject to the recipient's execution of a general release in favor of the company and its affiliates, as well as compliance with a perpetual confidentiality obligation, a non disparagement obligation, a covenant not to compete and a covenant not to solicit our customers or employees for 12 months following termination of employment. Finally, pursuant to the terms of the equity awards Mr. Krone received under the Leidos 2006 Equity Incentive Plan and 2017 Omnibus Incentive Plan (Equity Plans) if Mr. Krone is terminated by us for reasons other than for cause, by him for good reason, or by reason of his death or disability, he would be entitled to accelerated vesting, or pro-rated vesting, of his long-term incentive awards, depending on whether the termination is during a change in control period. The chart below provides the amounts that Mr. Krone would be entitled to under these various termination scenarios.

**MR. CAGE, MS. WATERSTON, MR. HOWE AND MR. FASANO**

All of our named executive officers, other than Mr. Krone, are covered by the Leidos Holdings, Inc. Executive Severance Plan, effective July 25, 2019 (Severance Plan).

The Severance Plan provides for the following in the event of a qualifying termination without Cause in the absence of a Change in Control or CIC:

▶A cash lump sum severance benefit of 1.0 times base salary plus a pro rata bonus based on actual performance;

▶A cash lump sum severance benefit equal to the premium cost of COBRA continuation of medical, dental and vision benefits for 12 months; and

▶Six months of outplacement services.

The Severance Plan is designed to provide enhanced severance benefits to executive officers in certain cases where their employment is terminated involuntarily without cause, with a separate set of benefits for an involuntary termination without cause or resignation for good reason that occurs within three months prior to or within 24 months following a CIC, with benefits in such circumstances to be:

▶A cash lump sum severance benefit of 1.5 times the sum of (i) base salary and (ii) target bonus;

▶Pro-rata annual bonus for the year of termination based on target performance;

▶A cash lump sum severance benefit equal to the premium cost of COBRA continuation of medical, dental and vision benefits for 18 months; and

▶12 months of outplacement services.

Benefits under this plan in connection with a CIC are "double trigger" and any payments under this plan are subject to the recipient's execution of a general release in favor of the company and its affiliates, as well as compliance with a perpetual confidentiality obligation, a non-disparagement obligation, a covenant not to compete and a covenant not to solicit our customers or employees for (i) 12 months following termination of employment in the case of a qualifying termination of employment in the absence of a CIC and (ii) 18 months following termination of employment in the case of a qualifying termination of employment in connection with a CIC.

Following a CIC, our executive officers would also vest in certain of their outstanding equity awards, if the CIC meets the definition in our Equity and Deferred Compensation Plans and subject to the recipient's execution of a general release in favor of the company and its affiliates, as well as compliance with a covenant not to compete and a covenant not to solicit employees or customers for 12 months after termination of employment. Finally, pursuant to the terms of the equity awards they received under the Equity Plan, if they terminated employment involuntarily not for cause, or by reason of their death or disability, they would be entitled to accelerated vesting, or pro-rated vesting, of certain long-term incentive awards. The charts below provide the amounts that these named executive officers would be entitled to under various termination scenarios.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

<sup>(3)</sup> Amounts in this row represent cash payments for (a) lump sum severance and (b) pro-rated annual bonuses for the year of termination. Severance amounts for Mr. Krone are equal to one times (in the event of termination without a CIC), and 2.5 times (in the event of termination in connection with a CIC), the sum of Mr. Krone's year end salary and bonus at target. Severance amounts for other executives reflect one year of annual base salary (for termination without a CIC), and 1.5 times the sum of annual base salary and target bonus (for termination in connection with a CIC). Mr. Krone's pro-rated annual bonus would be payable based on actual performance for the period ended December 31, 2022, in all scenarios. For the other executives, for the termination without a CIC, and death and disability scenarios, the bonus would be based on actual performance through December 31, 2022, and the number of days that elapsed during the performance period ended December 31, 2022. In the CIC scenario, the bonus amount is based on target performance results.

<sup>(4)</sup> For a termination not in connection with a CIC, the value reflects a portion of the named executive officer's RSUs (granted beginning in March 2018), pro-rated based on the number of days elapsed between the grant date and December 31, 2022, including accrued cash dividends as of December 31, 2022. For terminations in connection with a CIC, death, and disability, amounts represent the value of accelerated vesting of shares of all RSUs, including accrued dividends as of December 31, 2022, pursuant to the Leidos Equity and Deferred Compensation Plans. The retirement and non-termination scenarios for Messrs. Krone and Howe, assume their respective terminations would each qualify as a special retirement and amounts include the awards that would continue to vest. For more information regarding the number of shares of unvested RSUs held by the executive officers, see the table under the caption "Outstanding Equity Awards at Fiscal Year-End."

<sup>(5)</sup> For a termination without a CIC, the table reflects pro-rated amounts of stock options granted beginning in March 2018 that would vest based on the number of days elapsed between the grant date and December 31, 2022. The retirement and non-termination scenarios for Messrs. Krone and Howe assume their respective terminations would each qualify as a special retirement and amounts include the awards that would continue to vest after departure. For a termination in connection with a CIC, or upon death or disability, represents the value of accelerated vesting of all unvested options held by the named executive officer at the end of the year issued pursuant to the Leidos Equity Plans. For more information regarding the number of shares and exercise prices underlying unvested options held see the table under the caption "Outstanding Equity Awards at Fiscal Year-End."

<sup>(6)</sup> For a termination without a CIC and for disability, the values represent a pro-rata amount of performance share awards, including accrued cash dividends, based on actual performance as of December 31, 2022. Since Messrs. Krone and Howe qualify for special retirement, each would be entitled to associated pro-rated vesting (including accrued dividends) that would apply as a result. In the CIC and death scenarios, awards reflect full vesting, including accrued cash dividends, as of December 31, 2022; assumes target performance results for death and also in the event of a CIC for the 2021 and 2022 awards; the 2020 awards are assumed paid based on actual performance results as of December 31, 2022, in the event of a CIC.

<sup>(7)</sup> Amounts in this row reflect the total of (a) lump sum cash payments in lieu of providing benefits to the executives, and (b) cost estimates for providing outplacement benefits following a qualifying termination of employment. Benefit lump sums for all named executive officers other than Mr. Krone are equal to 12 months of COBRA premiums for medical, dental and vision coverage for terminations not in connection with a CIC, and 18 months of COBRA premiums for terminations in connection with a CIC. Mr. Krone's amounts reflect 12 months of COBRA premiums for medical, dental and vision coverage following a termination not in connection with a CIC and lump sum payments in lieu of continued life, disability, medical, dental and vision coverage for 30 months for terminations in connection with a CIC. Amounts also include estimates for providing outplacement counseling services for 12 months following termination of employment in connection with a CIC or, except for Mr. Krone, for 6 months if the termination is not in connection with a CIC.

<sup>(8)</sup> Estimates the benefits to be reduced to avoid the payment of excess parachute payments pursuant to Section 280G of the Internal Revenue Code.

<sup>(9)</sup> Amounts in this row represent the gross amount of benefits to be received by the named executive officer. In addition, the named executive officers would also be entitled to be paid for any unused comprehensive leave time accrued.

**TREATMENT OF EQUITY AWARDS UPON TERMINATION**

With respect to outstanding equity awards, our named executive officers are generally treated in the same way as all other employee award recipients if their employment is terminated due to death, disability, retirement, involuntary without cause departure, or voluntary departure.

In the case of death or disability, restricted stock units and options will vest immediately and options will remain exercisable for the remaining term of the option. For our performance share award program, target shares will be paid out promptly upon death. In the case of disability for all performance share awards, individuals will receive a pro-rata number of shares after the end of the applicable three-year performance period, based on actual company performance over the full period.

Under our continued vesting program, employees who retire, including our executive officers, may continue holding and vesting in their stock options if they have held such options for at least 12 months prior to retirement and they retire (i) after age 59 1/2 with at least 10 years of service or (ii) after age 59 1/2 when age at termination plus years of service equals at least 70. When an individual becomes eligible for continued vesting, restricted stock units will continue to vest in accordance with the original vesting schedule. Individuals meeting these qualifications who hold performance share awards will receive a pro-rata number of shares after the end of the applicable three-year performance period, based on actual company performance over the full period. We have the right to terminate continued vesting if an individual violates confidentiality, non-solicitation, non-compete, or similar obligations to us.

In the case of an involuntary termination without cause, all restricted stock units and stock options granted in 2017 or later will vest on a pro-rata basis provided the award has been held for a minimum of six months. In the case of a performance share award, individuals will receive a pro-rata number of shares after the end of the applicable three-year performance period, based on actual company performance over the full period, provided the award has been held for a minimum of 6 months.

In any other case, if the employment of an equity award recipient, including an executive officer, is terminated for any reason, all of that recipient's unvested restricted stock units, options and performance share awards are forfeited. Vested options remain exercisable for 90 days or until the option expiration date, if earlier.

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**Pay Ratio Disclosure**

In accordance with the requirements of Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K (which we collectively refer to as the "Pay Ratio Rule"), we are providing the following estimated information for 2022:

▶The median of the annual total compensation of all our employees (except our Chief Executive Officer) was $102,238;

▶The annual total compensation of our Chief Executive Officer was $13,548,892; and

▶The ratio of these two amounts was 133 to 1. We believe that this ratio is a reasonable estimate calculated in a manner consistent with the requirements of the Pay Ratio Rule.

SEC rules for identifying the median employee and calculating the pay ratio allow companies to apply various methodologies and apply various assumptions and, as a result, the pay ratio reported by us may not be comparable to the pay ratio reported by other companies.

**METHODOLOGY FOR IDENTIFYING OUR "MEDIAN EMPLOYEE"** 

**EMPLOYEE POPULATION**

To identify the median of the annual total compensation of all of our employees (other than our Chief Executive Officer), we first identified our total employee population from which we determined our "median employee." We selected December 30, 2022, which is within the last three months of fiscal 2022, as the date upon which we would identify the "median employee." We determined that, as of December 30, 2022, our employee population consisted of 45,463 individuals (of which approximately 89% were located in the United States and 11% were located in jurisdictions outside the United States). Our employee population consisted of our global workforce of full-time, part-time, and temporary employees, as described in more detail below.

**ADJUSTMENTS TO OUR EMPLOYEE POPULATION**

As permitted by the Pay Ratio Rule, we adjusted our total employee population (as described above) for purposes of identifying our "median employee" by excluding approximately 1,329 of our employees located in certain jurisdictions outside of the United States given the relatively small number of employees in those jurisdictions and the estimated costs of obtaining their compensation information, as follows: 314 employees from Japan, 146 employees from South Korea, 124 employees from Germany, 97 employees from Iraq, 81 employees from Singapore, 57 employees from Bahrain, 53 employees from India, 50 employees from Romania, 48 employees from Italy, 40 employees from Kuwait, 39 employees from Saudi Arabia, 38 employees from China, 27 employees from Israel, 26 employees from Kosovo, 25 employees from United Arab Emirates, 22 employees from Qatar, 20 employees from Djibouti, 17 employees from Canada, 15 employees from Ireland, 14 employees from Spain, 9 employees from the Philippines, 9 employees from Netherlands, 8 employees from Belgium, 7 employees from Jordan, 6 employees from Hong Kong, 4 employees from Turkey, 4 employees from Russia, 4 employees from Greenland, 4 employees from Greece, 3 employees from Poland, 3 employees from Cuba, 2 employees from Honduras, 2 employees from Niger, 2 employees from Kenya, 1 employee from Syria, 1 employee from Sint Maarten, 1 employee from Mexico, 1 employee from Malaysia, 1 employee from Latvia, 1 employee from France, 1 employee from Finland, 1 employee from Ethiopia, and 1 employee from Colombia. For each jurisdiction where we excluded employees, we excluded all employees in that jurisdiction.

After taking into account the above-described adjustments to our employee population as permitted by the Pay Ratio Rule, our total adjusted employee population for purposes of determining our "median employee" consisted of approximately 44,134 individuals.

**DETERMINING OUR MEDIAN EMPLOYEE**

To identify our "median employee" from our total adjusted employee population, we compared the annualized salary of our employees as reflected in our human resources system of record. We identified our "median employee" using this compensation measure, which was consistently applied to all our employees included in the calculation. After identifying the median employee, that employee's compensation was restated based on the Summary Compensation Table elements. Using the methodologies described above, we determined that our "median employee" was a full-time, salaried employee located in the United States with base wages for the 12-month period ending December 30, 2022, in the amount of $102,238.

2023 PROXY STATEMENT 75

PROPOSAL 2: ADVISORY VOTE ON EXECUTIVE COMPENSATION

**DETERMINATION OF ANNUAL TOTAL COMPENSATION OF OUR "MEDIAN EMPLOYEE" AND OUR CEO**

Once we identified our "median employee", we then calculated such employee's annual total compensation for 2022 using the same methodology we used for purposes of determining the annual total compensation of our named executive officers for 2022 (as set forth in the "Summary Compensation Table" in this Proxy Statement).

Our CEO's annual total compensation for 2022 for purposes of the Pay Ratio Rule is equal to the amount reported in the "Total" column in the "Summary Compensation Table" in this Proxy Statement.

**Pay versus Performance Disclosure**

This new, required table intends to compare "Pay versus Performance" and prescribes a method to calculate "Compensation Actually Paid" (CAP). The CAP values shown in the table below do not reflect the compensation actually paid to the Principal Executive Officer (PEO) or the Non-PEO NEOs. In addition, while the table shows the Summary Compensation Table (SCT) compensation and CAP values side by side, they are not comparable. As such, the Committee did not consider the information provided in the table structuring or determining compensation for our NEOs. For a complete discussion of our executive compensation program and the Committee's philosophy and approach, please refer to the CD&A section of this Proxy Statement (page [44](#if4d032a615334d44ab5a038068275fdc_440)).

Together with the salary and annual incentive, the SCT values include the accounting fair value of equity awards granted in the year shown (at the time the grant was made), whereas CAP values include a revaluation of the current grant at year-end, plus the year-over-year change in the fair value of multiple years of historical equity grants. Because CAP includes multiple years of grants, the calculation of CAP each year is heavily impacted by the change in the stock price, and therefore, may be higher or lower than the SCT compensation values.

The actual value of an equity award realized by an executive depends on several factors measured over multiple years, including the stock price, the financial performance of the company, the relative total shareholder return (TSR) performance of the company as compared to a peer group, timing of stock option exercises and other factors.

<sup>(2)</sup> Total Compensation as set forth in the Summary Compensation Table (page [67](#i19013f99d266455da86f7ac367fee52c_152380)) in this Proxy Statement for the applicable year (2021) for Mr. Krone (PEO) and average total compensation for the applicable year for Mr. Cage, Mr. Reagan, Mr. Fasano, Mr. Howe, and Ms. Schmanske (Non-PEO NEOs).

<sup>(3)</sup> Total Compensation as set forth in the Summary Compensation Table (page [67](#i19013f99d266455da86f7ac367fee52c_152380)) in this Proxy Statement for the applicable year (2020) for Mr. Krone (PEO) and average total compensation for the applicable year for Mr. Reagan, Mr. Fasano, Mr. Howe, and Mr. King (Non-PEO NEOs).

<sup>(4)</sup> The Compensation Actually Paid (CAP) is calculated by reducing the total compensation by grant date fair value of stock and options awards from the summary compensation table and adding equity awards adjustments for fiscal 2022. For each outstanding and unvested equity award, we utilized the fiscal year end and vesting date fair values to calculate the equity award adjustments. The fair value of options were determined by using a Black Scholes model, the relative TSR based PSUs were determined by using a Monte Carlo simulated pricing model, non-market based PSUs reflect the probable outcome of the performance vesting conditions as of each measurement date, and RSUs fair value equaling to the stock price on the appropriate measurement date. Amounts deducted from total compensation is $10,315,880 for the PEO and $1,520,126 for the average total for Non-PEO NEOs. Equity award adjustments total $16,013,295 for the PEO and $2,001,218 for the average total for Non-PEO NEOs. See table below for detailed calculations of the equity award adjustments made in order to calculate the CAP.

<sup>(5)</sup> The CAP is calculated by reducing the total compensation by grant date fair value of stock and options awards from the summary compensation table and adding equity awards adjustments for fiscal year 2021. For each outstanding and unvested equity award during the fiscal years covered in the table, we utilized the fiscal year end and vesting date fair values to calculate these equity award adjustments. The fair value of options were determined by using a Black Scholes model, the relative TSR based PSUs were determined by using a Monte Carlo simulated pricing model, non-market based PSUs reflect the probable outcome of the performance vesting conditions as of each measurement date, and RSUs fair value equaling to the stock price on the appropriate measurement date. Amounts deducted from total compensation is $9,482,900 for the PEO and $900,434 or the average total for Non-PEO NEOs. Equity award adjustments total $1,652,659 for the PEO and $(90,899) for the average total for Non-PEO NEOs. See table below for detailed calculations of the equity award adjustments made in order to calculate the CAP.

PROPOSAL 4: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

After assessing the qualifications, performance, and independence of Deloitte, the Audit and Finance Committee has approved the engagement of Deloitte as our independent registered public accounting firm for the fiscal year ending December 29, 2023. Deloitte has been the company's independent registered public accounting firm since fiscal 2000.

**Audit and Non-Audit Fees**

Aggregate fees billed for the 2022 and 2021 fiscal years by our independent registered public accounting firm, Deloitte, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates (collectively, the "Deloitte Entities"), were as follows:

---

| | | |
|:---|:---|:---|
| | **2022** | **2021** |
| Audit fees<sup>(1)</sup> | $6649100 | $6749000 |
| Audit-related fees<sup>(2)</sup> | $— | $— |
| Tax fees<sup>(3)</sup> | $295100 | $490300 |
| All other fees<sup>(4)</sup> | $5700 | $141300 |
| **Total fees** | $6949900 | $7380600 |

---

<sup>(1)</sup> Audit fees include professional services rendered for the audit of the annual consolidated financial statements (including services rendered for reporting on the Company's effectiveness of internal control over financial reporting) and reviews of quarterly consolidated financial statements. Audit fees also include services that are normally provided by the accountant in connection with statutory and regulatory filings or engagements, including statutory audits.

<sup>(2)</sup> Audit-related fees include professional services rendered to issue comfort letters in connection with bond offerings.

<sup>(3)</sup> Tax fees include a variety of permissible tax services related to preparation and/or review of statutory tax filings within U.S., foreign and state jurisdictions, general tax advisory services (including research and discussions related to tax compliance matters), tax planning and assistance with transfer pricing documentation and dispositions.

<sup>(4)</sup> All other fees relate to the purchase of accounting-related research software and agreed upon procedures.

**Pre-Approval Policies and Procedures**

The Audit and Finance Committee has considered whether the above services provided by the Deloitte Entities are compatible with maintaining the independence of the Deloitte Entities. The Audit and Finance Committee has the responsibility to pre-approve all audit and non-audit services to be performed by the independent registered public accounting firm in advance. Further, the Chair of the Audit and Finance Committee has the authority to pre-approve audit and non-audit services, as necessary, between regular meetings of the Audit and Finance Committee, provided that any such services so pre-approved shall be disclosed to the full Audit and Finance Committee at its next scheduled meeting. The Committee or the Committee chair pre-approved all of Deloitte's 2022 fees and services.

**Audit and Finance Committee Report**

The Audit and Finance Committee assists the Board in its oversight of: (i) the integrity of the company's financial statements, including the financial reporting process, system of internal control over financial reporting and audit process; (ii) the company's compliance with legal and regulatory requirements; (iii) the independent registered public accounting firm's qualifications and independence; (iv) the performance of the company's internal audit function and independent registered public accounting firm; and (v) financial reporting risk assessment and mitigation. The Audit and Finance Committee's job is one of oversight and it recognizes that management is responsible for the preparation and certification of the company's financial statements and the company's internal controls over financial reporting and that the independent registered public accounting firm is responsible for auditing those financial statements and the company's internal controls over financial reporting.

PROPOSAL 4: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit and Finance Committee recognizes that financial management, the internal audit staff and the independent registered public accounting firm have more time, knowledge, and detailed information on the company than do Audit and Finance Committee members. Consequently, in carrying out its oversight responsibilities, the Audit and Finance Committee is not providing any expert or special assurance as to the company's financial statements or any professional certification as to the independent registered public accounting firm's work.

The Audit and Finance Committee recognizes the importance of maintaining the independence of Leidos' independent auditor, both in fact and appearance. The Committee engages in an annual evaluation of the independent registered public accounting firm. It considers, along with company management and internal auditors, (i) the audit firm's independence and objectivity, (ii) the capability and experience of the firm's proposed audit team members, (iii) the audit firm's audit quality indicators, (iv) the advantages and possible disadvantages of the audit firm's tenure as our independent auditors, (v) the appropriateness of the audit firm's fees for audit and non-audit services, (vi) the audit firm's capability and expertise in our industry and in auditing companies with broad and complex operations, (vii) the audit firm's performance and proposed approach to auditing the company's financial statements and the company's internal controls over financial reporting, and (viii) the size and reputation of the audit firm. After assessing the qualifications, performance, and independence of Deloitte, the Audit and Finance Committee has approved the engagement of Deloitte as our independent registered public accounting firm for the fiscal year ending December 29, 2023. Deloitte has been the company's independent registered public accounting firm since fiscal 2000.

Deloitte rotates its lead audit engagement partner at least every five years. The Audit and Finance Committee interviews proposed candidates and selects the lead audit engagement partner.

The duties and responsibilities of the Audit and Finance Committee have been set forth in a written charter since 1975. A copy of the current Audit and Finance Committee charter is available on the company's website at www.leidos.com by clicking on the links entitled "Investors," "Corporate Governance" and then "Board Committees." Each member of the Audit and Finance Committee meets the independence and financial literacy requirements of the SEC and the NYSE. In addition, except for Mr. Dahlberg, all of the Committee members qualify as audit committee financial experts under SEC rules.

In the course of fulfilling its responsibilities, the Audit and Finance Committee has:

▶Met separately with the internal auditor and the independent registered public accounting firm to discuss any matters that the internal auditor, the independent registered public accounting firm or the Committee believed should be discussed privately without members of management present;

▶Met with management of the Company to discuss any matters management or the Committee believed should be discussed privately without the internal auditor or the independent registered public accounting firm present;

▶Reviewed and discussed with management and Deloitte, the Company independent registered public accounting firm, the audited consolidated financial statements for the fiscal year ended December 30, 2022;

▶Discussed with Deloitte the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) Standards and the SEC; and

▶Received the written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding Deloitte's communications with the Audit and Finance Committee concerning independence, and has discussed with Deloitte its independence.

Based on the reviews and discussions summarized in this Report and subject to the limitations on our role and responsibilities referred to above and contained in the Audit and Finance Committee charter, the Audit and Finance Committee recommended to the Board of Directors that the Company's audited consolidated financial statements referred to above be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 30, 2022, for filing with the SEC.

Richard Lippert has advised us that he intends to introduce the following resolution:

WHEREAS: Leidos Holdings, Inc. sponsors a federal political action committee (PAC) whose decisions are based on Leidos' publicly expressed goals and the best interests of the company, the employees, and the shareholders.

Leidos states: Everything we do is built on a commitment to do the right thing for our customers, our people, and our community. Leidos makes the world safer, healthier, and more efficient through technology, engineering, and science. We strengthen our communities through volunteerism, sustainable operations, and the advancement of equality. The Leidos core values are integrity, inclusion, innovation, agility, collaboration, and commitment.

However, Leidos' politically focused expenditures appear to be misaligned with its public statements on Company values, vision, and operational practices. As examples, Leidos states:

▶We are committed to a culture that provides equitable access to opportunities and resources for everyone, yet Proponent estimates that in the 2021-2022 election cycles, Leidos and its employee PAC made political donations totaling at least $460,500 to politicians and political organizations working to weaken women's access to reproductive health care.

▶We seek to advance environmental sustainability by doing our part to preserve natural resources, reduce emissions and limit waste, yet Leidos is a member of the U.S. Chamber of Commerce which has consistently lobbied to roll back climate regulations and slow the transition toward a low carbon energy mix.

▶We are building a workplace that cultivates opportunity, advances equality, and is free from discrimination, inequity and maltreatment, yet Leidos is receiving negative media attention for PAC contributions to candidates who are making discriminatory statements against a protected class. Integrity is a core value, yet the Leidos PAC has contributed $144,000, to 33 candidates who voted against certifying the 2020 election and continue to promote the "big lie" that the election was stolen.

BE IT RESOLVED: Shareholders request that Leidos publish a report, at reasonable expense, analyzing the congruence of the Company's political and electioneering expenditures during the preceding year against publicly stated company values and policies, listing and explaining any instances of incongruent expenditures, and stating whether the Company has made, or plans to make, changes in contributions or communications to recipients as a result of identified incongruencies.

SUPPORTING STATEMENT: Proponents recommend, at Board and management discretion, that the report also include management's analysis of risks to the Company brand, reputation, or shareholder value associated with expenditures in conflict with its publicly stated company values. Expenditures for electioneering communications means spending, from corporate treasury and from the PACs, directly or through a third party, at any time during the year, on printed, internet, or broadcast communications, which are reasonably susceptible to interpretation as being in support of or opposition to a specific candidate.

PROPOSAL 5: STOCKHOLDER PROPOSAL REGARDING REPORT ON POLITICAL EXPENDITURES CONGRUENCE

**Board Response to Proposal 5**

Our Board believes that responsible corporate citizenship demands a strong commitment to a healthy and informed democracy through civic and community involvement. With a focus on delivering mission-critical solutions, we generated 86% of revenues for the fiscal year ending December 30, 2022, from U.S. government contracts. Furthermore, Leidos is subject to extensive laws and regulations which can significantly affect our business and operations. Given the potential impact public policy can have on our businesses, employees, and customers, Leidos engages with policymakers to advance and protect the company's and our stockholders' long-term interests.

**How We Participate in the Political Process**

The Leidos Government Affairs team (LGA) leads our engagement in complex policy matters while maintaining the company's commitment to being a thoughtful and constructive participant in the public policy process. The LGA and our executives represent Leidos' business interests before the U.S. Congress, the Executive Branch, state legislatures, and industry associations to educate, inform, and advocate on behalf of the company, our employees, and our stockholders. Leidos' political engagement is subject to a comprehensive governance process and oversight by the Corporate Governance and Ethics Committee of the Board of Directors. Our engagement is conducted without regard to the personal political preferences of individual board members, officers or employees.

**Our Commitment to Transparency** 

We are committed to transparency as we engage in public advocacy activities to further our mission. We maintain a website at www.leidos.com/company/responsibility-and-sustainability/political-activities with a discussion of our political activities that includes:

▶Links to federal reports disclosing all lobbying activities and expenses;

▶A list of significant trade association memberships;

▶An aggregate list of contributions to candidates and committees for 2021 and 2022 by the Leidos Political Action Committee (LPAC); and

▶LPAC's criteria to evaluate candidates and contributions, and the governance process to reconsider them on a periodic basis.

Our political activities are subject to extensive governmental regulation and public disclosure requirements, which require us to file regular, publicly-available and detailed reports. Our Board believes that the information currently made available strikes the appropriate level of transparency and that additional disclosures with respect to lobbying and political expenditures would not provide useful information to stockholders. Moreover, implementing the proposal's other requirements would result in the unproductive consumption of valuable time and corporate resources without materially enhancing existing disclosures.

**Trade Association Memberships**

Leidos belongs to several trade associations, including, but not limited to, the United States Chamber of Commerce, the National Defense Industrial Association, the American Institute of Aeronautics and Astronautics, the Association of the United States Army, the Professional Services Council, and the Business Roundtable. These trade associations advocate major public policy issues important to the company and our employees. We may not always agree with all the positions of an association or its other members and we voice our concerns as appropriate through Leidos Government Affairs and Leidos leaders who interact with these associations. Leidos regularly evaluates our trade association memberships to ensure our participation in these organizations is consistent with our corporate values and business interests on key issues.

**What is the Leidos PAC, and How Does it Further Leidos' Interests?**

Leidos employees may participate voluntarily in the political process by joining the LPAC. This non-partisan political action committee keeps employees aware of important issues and decisions made by government officials that can affect our business. The LPAC also allows our employees to pool their financial resources to support political candidates, campaigns, and committees to promote the best interests of Leidos, its stockholders, and employees.

Leidos does not contribute its corporate funds to candidates, political party committees or the LPAC's disbursement account.

PROPOSAL 5: STOCKHOLDER PROPOSAL REGARDING REPORT ON POLITICAL EXPENDITURES CONGRUENCE

**Oversight and Monitoring of the LPAC'S Political Activities**

In accordance with its bylaws, the LPAC is overseen by a Board of Directors appointed by the Chief Executive Officer consisting of no fewer than seven (7) senior company leaders representing all aspects of the company. The LPAC Board of Directors approves contributions to candidates and committees based on the LPAC Candidate Giving Criteria and reviews all contributions periodically for conformity of the criteria. The LPAC Board of Directors also ensures all contributions made by the LPAC are reported to the Federal Election Commission in accordance with LPAC bylaws and federal law. The LPAC's contribution reports can be reviewed on the Federal Election Commission's website. In addition, as part of our commitment to transparency, a list of candidates and committees that LPAC supports is available on Leidos' corporate website.

**LPAC's Candidate Giving Criteria**

The LPAC Candidate Giving Criteria include, but are not necessarily limited to:

▶The integrity and character of the candidate;

▶The candidate's position and voting record on business-related issues and/or economic questions of national and international importance;

▶Whether the candidate holds a leadership or policy-shaping position on a legislative committee or is likely to hold such a position in the future;

▶The nature and strength of the candidate's opposition in the primary or general elections;

▶Financial need and other sources of financial assistance available to the candidate; and

▶Whether the candidate represents a geography in which Leidos has facilities, business interests, or employees.

The LPAC may pause contributions to candidates if the Integrity and Character criteria are violated, following the process below:

1. Actual or potential violation of the Character and Integrity Criteria, such as an active investigation of ethical or criminal misconduct;

2. LPAC Manager informs LPAC Chair;

3. LPAC Chair immediately pauses political donations to named members;

4. LPAC Board of Directors convenes and holds a vote to pause political donations; and

5. LPAC Board of Directors reconsiders paused contributions on a periodic basis.

Notably, members of the LPAC may choose to direct their contributions to a specific political party. If the LPAC member has no political preference, their contributions will be allocated according to the bipartisan LPAC Candidate Giving Criteria.

**Alignment Between our Spending and our Values**

We have effective reporting and compliance procedures designed to ensure that our political contributions are made following applicable law, and we monitor the appropriateness and effectiveness of the political activities undertaken. Such processes also ensure that our political engagement is aligned with our corporate values.

We believe that participating in the political process in a bipartisan and transparent manner, together with our encouragement of our employees to participate in the political process to address their own diverse interests and priorities, both enhance shareholder value and promote good corporate citizenship. We also believe that the reporting requested by the proposal will divert us from our focus on core business priorities and impede our ability to participate in a bipartisan manner.

The Board of Directors recommends that stockholders vote **AGAINST** this proposal.

Kenneth Steiner has advised us that he intends to introduce the following resolution:

**Proposal 6 - Independent Board Chairman**

![ldos-20230315_g136.jpg](ldos-20230315_g136.jpg)

Shareholders request that the Board of Directors adopt an enduring policy, and amend the governing documents as necessary in order that 2 separate people hold the office of the Chairman and the office of the CEO.

Whenever possible, the Chairman of the Board shall be an Independent Director.

The Board has the discretion to select a Temporary Chairman of the Board who is not an Independent Director to serve while the Board is seeking an Independent Chairman of the Board.

Although it is a best practice to adopt this policy soon this policy could be phased in when there is a contract renewal for our current CEO or for the next CEO transition.

The roles of Chairman and CEO are fundamentally different and should be held by 2 directors, a CEO and a Chairman who is completely independent of the CEO and our company. "The job of the CEO is to manage the company. The job of the Chairman is to oversee the CEO and management.

This proposal topic won 42% support at a previous Leidos annual meeting. This 42%-vote may have represented a majority vote from the more informed Leidos shareholders who have access to independent proxy voting advice.

A lead director is no substitute for an independent Board Chairman. A lead director is not responsible for the strategic direction of the company. And a Chairman/CEO can ignore the advice and feedback from a lead director. According to the Leidos Corporate Governance Guidelines the Lead Director may have a somewhat ceremonial role.

Apparently the Lead Director does not collaborate with the Chairman on Board meeting schedules, he merely approves the schedules after the fact. The lead director has a "help" role, an "available" role, an "input" role on information that the Board has access to (that seems to mean that the "input" can be ignored).

The Leidos lead director seems to lack in having exclusive powers. Management fails to give shareholders enough information on this topic to make an informed decision in favor of management. There is no management comparison of the exclusive powers of the Office of the Chairman and the de minimis exclusive powers of the lead director.

In response to this proposal perhaps Mr. Robert Shapard, Leidos lead director and meanwhile the Chairman of the Board at Oncor Electric Delivery Company, can give specifics on the difference in duties and powers between a Chairman and a lead director.

Please vote yes:

**Independent Board Chairman - Proposal 6**

2023 PROXY STATEMENT 87

------

PROPOSAL 6: STOCKHOLDER PROPOSAL REGARDING INDEPENDENT BOARD CHAIR

**Board Response to Proposal 6**

Our Board believes that this proposal is unnecessary because the Board has decided to appoint an independent Board Chair effective immediately following the 2023 annual meeting of stockholders.

The Board believes that it is in the best interests of stockholders for the Board to have the flexibility to determine the most qualified and appropriate individual to serve as Chair of the Board. The Board has been led by Roger A. Krone as Chair and Chief Executive Officer and Robert S. Shapard as Lead Independent Director. With Mr. Krone's resignation as CEO and upcoming retirement as Board Chair at the Annual Meeting, the Board has appointed Thomas A. Bell to become the new CEO to replace Mr. Krone in that role, and Mr. Shapard will become the independent Chair of the Board following the 2023 annual meeting of stockholders. In essence, the Board has implemented the objective of the Proposal.

Mr. Shapard will be empowered with, and will exercise, robust, well-defined duties, which are expected to include:

1. Presiding over and managing the meetings of the board;

2. Supporting a strong board culture by fostering an environment of open dialogue, ensuring effective information flow and constructive feedback among the members of the board and senior management, facilitating communication among the Chair, the Board as a whole, Board committees, and senior management, and encouraging director participation in discussions;

3. Approving the scheduling of meetings of the Board, leading the preparation of the agenda for each meeting, and approving the agenda and materials for each meeting;

4. Calling and chairing all meetings of the independent directors;

5. Serving as liaison between management and independent directors; Representing the Board at annual meetings of stockholders and being available, when appropriate, for consultations and direct communication with shareholders and other key stakeholders;

6. Acting as an advisor to the CEO on strategic aspects of the business;

7. On behalf of the independent directors, retaining such counsel or other advisors as they deem appropriate in the conduct of their duties and responsibilities; and

8. Such other duties as prescribed by the Board.

We believe that our Board leadership structure provides for an effective governance framework. We also maintain strong independent and effective oversight of our business through our Audit and Finance, Human Resources and Compensation and Corporate Governance and Ethics Committees, which are each led by and comprised entirely of independent directors, experienced and committed directors and frequent executive sessions without management in attendance.

In addition, eleven of our twelve directors are independent. Our Corporate Governance Guidelines provide that if the Chair of the Board is not an independent director, the Corporate Governance and Ethics Committee will nominate an independent director to serve as Lead Independent Director to be approved by a majority of the independent directors. The specific responsibilities of the Lead Independent Director would include, among other duties, reviewing and approving meeting agendas and the annual schedule of meetings, calling and chairing all meetings of the independent directors and serving as the liaison between the independent directors and the Chief Executive Officer.

In summary, our Board believes that our Board leadership structure fulfills the request in the Proposal by providing for objective, independent Board leadership, effective engagement with and oversight of management and our business, and a voice that is independent from management and accountable to stockholders and other stakeholders.

The Board continues to maintain the flexibility to determine the leadership structure best suited to face the then current challenges facing the Company and to assess and select the best candidate for the position.

For the reasons mentioned above, the Board believes this proposal is unnecessary and limiting.

We welcome dialogue with all stockholders regarding all corporate matters. Methods for communicating with the Board are described under "Corporate Governance – Communications with the Board of Directors." Communications are also welcome through our Investor Relations website at investors.leidos.com.

The Board of Directors recommends that stockholders vote **AGAINST** this proposal.

**Delinquent Section 16(a) Reports**

Section 16(a) of the Securities Exchange Act of 1934 and the rules of the SEC require our directors and executive officers to file reports of their ownership and changes in ownership of common stock with the SEC. Our personnel generally prepare and file these reports for our directors and officers on the basis of information obtained from each director and officer and pursuant to a power of attorney. Due to an administrative error, one Form 4 for each of Messrs. Cage, Engola, Krone, King, Ms. Schmanske, Mr. Stevens, Ms. Porter and Mr. Fasano underreported the number of shares withheld by the Company to satisfy the reporting person's tax obligation associated with the vesting of previously reported awards of restricted stock units. An amendment to each of such Form 4s was filed 14 days later. Based upon a review of filings with the SEC and/or written representations that no other reports were required, we believe that all of our directors and executive officers and, to our knowledge, beneficial owners of more than 10% of our common stock otherwise complied during fiscal 2022 with the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934.

Frequently Asked Questions

**Can I attend the annual meeting?**

If you held shares of Leidos common stock as of the record date, you may attend the 2023 annual meeting. Because seating is limited, only you and one guest may attend the meeting. Admission to the meeting is on a first-come, first-served basis. Registration begins at 8:00 a.m. Eastern Time. You must present a valid government-issued picture identification and proof of Leidos stock ownership as of the record date. If you hold Leidos stock in street name, you must also bring a copy of a brokerage statement reflecting your stock ownership as of the record date. If you plan to attend as the proxy of a stockholder, you must present a legal proxy from your bank, broker, trust or other nominee in order to vote. Stockholders of record also may be represented by another person at the annual meeting by executing a legal proxy designating that person as the proxy holder. Each stockholder may appoint only one proxy holder or representative to attend the annual meeting on their behalf. Cameras, recording devices and other large electronic devices such as tablets or laptops, as well as backpacks or other large bags or packages are not permitted in the meeting. If you require special assistance at the meeting because of a disability, please contact the Corporate Secretary at Leidos' address in the notice.

**What constitutes a quorum?**

The presence, either virtually in person or by proxy, of the holders of a majority of the total voting power of the shares of common stock outstanding as of March 6, 2023, is necessary to constitute a quorum and to conduct business at the annual meeting. Abstentions and broker non-votes will be counted as present for purposes of determining the presence of a quorum.

**What is a broker non-vote?**

A broker "non-vote" occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that matter and has not received voting instructions from the beneficial owner. In tabulating the voting results for a particular proposal, broker non-votes are not counted as a vote on that proposal. Broker non-votes will not have an effect on the outcome of any matter being voted on at the meeting, assuming a quorum is present.

Unless you provide voting instructions to any broker holding shares on your behalf, your broker may not use discretionary authority to vote your shares on any of the matters to be considered at the annual meeting other than the ratification of our independent registered public accounting firm. Please vote your proxy or provide voting instructions to your broker so your vote can be counted.

**How many votes am I entitled to?**

Each holder of common stock will be entitled to one vote per share, in person or by proxy, for each share of stock held in such stockholder's name as of March 6, 2023, on any matter submitted to a vote of stockholders at the annual meeting. There were 137,193,302 shares of our common stock outstanding on March 6, 2023.

See "Can I attend the Annual Meeting?" above for more information regarding attending the annual meeting. If you hold your shares of Leidos common stock in street name, you must bring a valid government-issued picture identification and a copy of a statement reflecting your stock ownership as of the record date to attend the meeting.

The mailing address of our mailing agent is Broadridge, 51 Mercedes Way, Edgewood, NY 11717. Simply attending the annual meeting will not revoke a proxy.

**What vote is required for the matters to be voted upon at the meeting?**

▶Proposal 1: The election of directors at the 2023 annual meeting is uncontested. In an uncontested election, nominees must receive a majority of votes cast (meaning the number of votes cast "for" a nominee must exceed the number of votes cast "against" that nominee). Abstentions and broker non-votes are not counted as votes cast.

▶Proposal 2: This advisory vote on executive compensation is non-binding on the Board. The affirmative vote of a majority of the shares present or represented either in person or by proxy and entitled to vote on the matter is required to approve this proposal. Abstentions will have the effect of a vote against the proposal and broker non-votes will not be counted in evaluating the results of the vote.

FREQUENTLY ASKED QUESTIONS

▶Proposal 3: This advisory vote on the frequency of future advisory votes on executive compensation is non-binding on the Board. Stockholders will be able to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain. The affirmative vote of a majority of the shares present or represented either in person or by proxy and entitled to vote on the matter is required to approve this proposal. Abstentions will have the effect of a vote against the proposal and broker non-votes will not be counted in evaluating the results of the vote. If none of the three frequency choices receives a majority, the Board will consider the frequency choice that received the most votes cast to be the choice selected by stockholders, in which case abstentions will have no effect.

▶Proposal 4: The affirmative vote of the holders of a majority of the voting power of common stock, present or represented either in person or by proxy and entitled to vote on the matter at the annual meeting is required to approve the proposal. Abstentions have the effect of a vote against the proposal. As noted above, brokers that have not received voting instructions from a beneficial owner have discretionary authority to vote on this proposal, meaning there are no broker non-votes.

▶Proposals 5 and 6: The affirmative vote of the holders of a majority of the voting power of common stock, present or represented either in person or by proxy and entitled to vote on the matter is required to approve the proposal. Abstentions have the effect of a vote against the proposal, and broker non-votes have no effect on the outcome of the proposal.

**What are the voting deadlines?**

For shares not held in the Leidos, Inc. Retirement Plan (the "Leidos Retirement Plan"), the deadline for submitting a proxy using the internet or the telephone is 11:59 p.m. ET on April 27, 2023. For shares held in the Leidos Retirement Plan, the deadline for submitting voting instructions using any of the allowed methods is 11:59 p.m. ET on April 25, 2023.

**How are the shares held by the Leidos Retirement Plan voted?**

Each participant in the Leidos Retirement Plan has the right to instruct Vanguard Fiduciary Trust Company, as trustee of the Leidos Retirement Plan (the "Trustee"), on a confidential basis, how to vote such participant's proportionate interests in all shares of common stock held in the Leidos Retirement Plan. The Trustee will vote all shares held in the Leidos Retirement Plan for which no voting instructions are received in the same proportion as the shares for which voting instructions have been received.

The Trustee's duties with respect to voting the common stock in the Leidos Retirement Plan are governed by the fiduciary provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The fiduciary provisions of ERISA may require, in certain limited circumstances, that the Trustee override the votes of participants with respect to the common stock held by the Trustee and to determine, in the Trustee's best judgment, how to vote the shares.

**How are the shares held by the Stock Plans voted?**

Under the terms of our Management Stock Compensation Plan and Key Executive Stock Deferral Plan, Matrix Trust Company, as trustee of these stock plans, has the power to vote the shares of common stock held in these stock plans. Matrix will vote all such shares in the same proportion that our other stockholders collectively vote their shares of common stock. If you are a participant in these stock plans, you do not have the right to instruct Matrix on how to vote your proportionate interests in the shares of common stock held in these stock plans.

**What is the difference between a "stockholder of record" and a "beneficial" holder?**

These terms describe how your shares are held. If your shares are registered directly with Computershare, our transfer agent, then you are a "stockholder of record" of these shares. If your shares are held in an account at a broker, bank, trust or other similar organization, then you are a "beneficial" holder of these shares. The organization holding your account is considered the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to instruct that organization on how to vote the shares held in your account.

**Who is soliciting these proxies?**

We are soliciting these proxies and the cost of the solicitation will be borne by us, including the charges and expenses of persons holding shares in their name as nominee incurred in connection with forwarding proxy materials to the beneficial

owners of such shares. In addition to the use of the mail, proxies may be solicited by our officers, directors and employees in person, virtual communication channels, by telephone or by email.

Such individuals will not be additionally compensated for such solicitation but may be reimbursed for reasonable out-of-pocket expenses incurred in connection with such solicitation.

We have also hired Morrow Sodali, LLC, 333 Ludlow Street, 5th Floor, South Tower, Stamford, CT 06902, to assist in the solicitation and distribution of proxies, for which they will receive a fee of $15,000, as well as reimbursement for certain out-of-pocket costs and expenses.

**What is "householding" and how does it affect me?**

We have adopted a procedure approved by the Securities and Exchange Commission, or SEC, called "householding." Under this procedure, we send only one proxy statement and one annual report to eligible stockholders who share a single address, unless we have received instructions to the contrary from any stockholder at that address. This practice is designed to reduce our printing and postage costs. Stockholders who participate in householding will continue to receive separate proxy or voting instruction cards. We do not use householding for any other stockholder mailings.

If you are a registered stockholder residing at an address with other registered stockholders and wish to receive a separate copy of the proxy statement or annual report, or if you do not wish to participate in householding and prefer to receive separate copies of these documents in the future, please contact our mailing agent, Broadridge, either by calling toll-free at 1-800-542-1061, or by writing to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, NY 11717. If you own shares through a bank, broker, or other nominee, you should contact the nominee concerning householding procedures. We will promptly deliver a separate copy of the proxy statement or annual report to you upon request.

If you are eligible for householding, but you and other stockholders of record with whom you share an address currently receive multiple copies of the proxy statement or annual report and you wish to receive a single copy of each of these documents for your household, please contact our mailing agent, Broadridge, at the telephone number or address indicated above.

**Where can I find the voting results of the annual meeting?**

We intend to announce preliminary voting results at the annual meeting and publish final results in a Current Report on Form 8-K to be filed with the SEC within four business days of the annual meeting.

**May I obtain a copy of the 2022 Annual Report on Form 10-K?**

We will provide without charge to any stockholder, upon written or oral request, a copy of our annual report without exhibits. Requests should be directed to Leidos Holdings, Inc., 1750 Presidents Street, Reston, Virginia 20190, Attention: Corporate Secretary or by calling 1-571-526-6000.

Other Matters

**Stockholder Proposals for the 2024 Annual Meeting**

Any stockholder proposals pursuant to Rule 14a-8 intended to be presented at the 2024 annual meeting of stockholders must be received by us at our principle executive offices at 1750 Presidents Street, Reston, Virginia 20190 no later than November 16, 2023, in order to be considered for inclusion in our Proxy Statement and form of proxy relating to that meeting.

Our proxy access bylaws permit a stockholder or group of stockholders (up to 20) who have owned at least three percent of common stock for at least three years to submit director nominees for inclusion in our Proxy Statement if the nominating stockholder(s) satisfies the requirements specified in the bylaws. To be timely, the notice must be delivered to the Corporate Secretary not later than the close of business on the 120th day, nor earlier than the close of business on the 150th day, prior to the first anniversary of the date that the proxy statement for the annual meeting was sent to stockholders. In the event, however, that the annual meeting is not scheduled to be held within a period that begins 30 days before the first anniversary date of the preceding year's annual meeting of stockholders and ends 30 days after the first anniversary date of the preceding year's annual meeting of stockholders, then the notice of nomination must be provided by the later of the close of business on the date that is 180 days prior to the annual meeting or the tenth day following the date such annual meeting is first publicly announced or disclosed. Therefore, in connection with the 2024 annual meeting of stockholders, notice must be delivered to the Corporate Secretary between October 17, 2023 and November 16, 2023. Such notice must comply with the additional requirements of our bylaws.

In addition, Sections 2.07 and 3.03 of our bylaws provides that, in order for a stockholder to propose any matter (including nominations for directors) for consideration at the annual meeting (other than by inclusion in the Proxy Statement), such stockholder must give timely notice to our Corporate Secretary of such stockholder's intention to bring such business before the meeting. To be timely, notice must be delivered to the Corporate Secretary not later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the preceding year's annual meeting. In the event, however, that the date of the annual meeting is more than 30 days before or more than 70 days after such anniversary date, notice by the stockholder must be delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made by us, whichever occurs later. Therefore, in connection with the 2024 annual meeting of stockholders, notice must be delivered to the Corporate Secretary between December 30, 2023 and January 29, 2024. Such notice must comply with the additional requirements of our bylaws.

**Internet Availability of Proxy Materials**

As permitted by the rules of the SEC, we are using the internet as a means of furnishing proxy materials to our stockholders. We believe this method will make the proxy distribution process more efficient, lower costs and help in conserving natural resources.

On or about March 15, 2023, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy materials, including our proxy statement and annual report. The Notice of Internet Availability of Proxy Materials also instructs you on how to access your proxy or voting instruction card to be able to vote through the internet or by telephone. Other stockholders, in accordance with their prior requests, and employees with regular access to email have received email notification of how to access our proxy materials and vote via the internet or by telephone or have been mailed paper copies of our proxy materials or a proxy and voting instruction card.

**Important Notice Regarding the Availability of Proxy Materials for the Annual Stockholders Meeting To Be Held on April 28, 2023.**

The proxy statement and annual report are available at www.proxyvote.com.

Information and reports on our website to which we refer in this proxy statement will not be deemed a part of, or otherwise incorporated by reference into, this proxy statement.
