2025 PROXY STATEMENT SUMMARY

EXECUTIVE COMPENSATION

We have designed our performance-based executive compensation program to attract, motivate, and retain highly qualified executives, incentivize them to achieve business objectives, reward performance, and align the interests of our executives with the interests of our stockholders and other stakeholders.

We have consistently received exceptionally strong stockholder say-on-pay support. The following table sets forth the voting results for our “say-on-pay” proposal for the last five years:

Annual Meeting	2024		2023		2022		2021		2020
Votes Cast “FOR” Say-On-Pay Proposal*		96%		97%		97%		97%		97%

*    Excludes broker non-votes

PERFORMANCE-BASED PROGRAM

The fundamental philosophy of our executive compensation program, set by the Compensation Committee of the Board, is pay-for-performance. Our 2024 results were impacted by adverse macroeconomic conditions, including inflationary pressures and labor and supply chain challenges, primarily on our ships contracted prior to the outbreak of the COVID-19 pandemic. We have included below highlights of our financial performance for 2024.

2024 Financial Information	($ in millions, except per share data)
Contract Awards	12,127

2025 PROXY STATEMENT SUMMARY

2024 STOCKHOLDER RETURNS

HII’s total stockholder return in 2024 was (25.7)%. We returned $368 million to our stockholders in 2024 through dividends and share repurchases. The following graph and chart show total stockholder return for HII in 2024 compared to benchmark total stockholder returns and total cash returned to stockholders in 2024, respectively.

1-Year Total Stockholder return

Returned $368 Million to Stockholders in 2024

ELEMENTS OF OUR EXECUTIVE COMPENSATION PROGRAM

Our compensation program consisted primarily of the following direct compensation elements:

Base Salary	Annual Incentive Awards	Long-Term Equity-Based Incentive Awards
Provides a minimum fixed level of compensation.	Generally paid in cash, under our Annual Incentive Plan (“AIP”) to motivate our executives to achieve pre- determined annual financial and operational targets that are aligned with our strategic goals.	Paid in the form of Restricted Performance Rights (“RPSRs”), which promote achievement of pre-determined performance goals over a three-year period that are aligned with long-term stockholder interests, and Restricted Stock Rights (“RSRs”).

Our compensation program is designed to balance performance-based compensation over the short- and long-term to incentivize decisions and actions that promote stockholder value and focus our executives on performance that benefits our stockholders and customers, while discouraging inappropriate risk-taking behaviors. A significant portion of the potential compensation of our executives is at risk, and that risk increases with corresponding increases in an executive’s level of responsibility.

2025 Proxy Statement 7

2025 PROXY STATEMENT SUMMARY

2024 TOTAL DIRECT COMPENSATION MIX

The pay for performance philosophy of our executive compensation program is demonstrated by the compensation mix of our NEOs. Of the three primary elements of total direct compensation, our executive compensation is heavily weighted towards the variable, performance-based elements and long-term and equity-based elements, as reflected in the following charts, which set forth the percentage of total compensation corresponding to each compensation element received by our CEO and by our other NEOs collectively in 2024.

CEO Compensation Mix(1)

Other NEOs Compensation Mix(2)

(1)Total direct compensation does not include perquisites and other benefits.

(2)Chart reflects average allocation for the NEOs other than our CEO. Total direct compensation does not include perquisites and other benefits.

COMPENSATION BEST PRACTICES

We believe our compensation practices are aligned with and reinforce our pay for performance philosophy and our related executive compensation principles.

We Do The Following

We Don’t Do The Following

Consideration of annual stockholder “say-on-pay” advisory vote on executive compensation.   Pay for performance compensation program heavily weighted toward variable, performance-based elements and toward long-term and equity-based elements.   Annual assessment of potential risk posed by our compensation programs.   Executive compensation “clawback” policy.   Targeted external compensation benchmarking.   Independent compensation consultant engaged by Compensation Committee.   Executive stock ownership guidelines based upon multiple of executive’s base salary.

No employment agreements for executives.   No change-in-control agreements for executives or related executive tax gross-up benefits.   Prohibitions against speculative transactions in our securities, pledging our securities as collateral and hedging transactions involving our securities.   No dividends or dividend equivalents paid on RPSRs or RSRs prior to vesting.

8 Huntington Ingalls Industries, Inc.

STOCKHOLDER ENGAGEMENT

We believe stockholder outreach and engagement is a corporate governance best practice. We regularly engage with our stockholders to inform management and the Board on those matters of most importance to our stockholders. This ongoing engagement provides stockholders an opportunity to share their perspectives and helps the Company identify and assess emerging areas of importance that may help shape our governance practices.

We strive for a collaborative approach to stockholder engagement and value the variety of stockholder perspectives we receive. Management and, in some cases, members of the Board actively engage with our stockholders to understand their perspectives on our Company, including our strategy, performance, corporate governance practices, executive compensation program, and sustainability efforts.

During 2024 and early 2025, we offered engagement meetings with the corporate governance teams of our largest stockholders and met with those stockholders that accepted our meeting invitations. These corporate governance engagement efforts, together with our other engagement efforts with institutional stockholders, represented approximately 66% of our total shares outstanding. In March 2024, we also held an Investor Day at the New York Stock Exchange (“NYSE”).

We are committed to understanding the perspectives of our stockholders and responding, as appropriate, giving consideration to their input along with corporate governance trends and best practices.

PROPOSAL 1	Election of Directors The Board has nominated 12 individuals for election as directors at the Annual Meeting. Each director nominee is a current HII Board member.
		The Board recommends a vote FOR each of the 12 director nominees.

Director Election Process

Our directors are elected to one-year terms in accordance with our Bylaws and Certificate of Incorporation. Each director nominee will hold office until the next annual meeting of stockholders or until his or her earlier death, resignation or removal. They have consented to serve, and we do not know of any reason why they would be unable to serve, if elected. If any nominee is unable to serve as a director, which we do not anticipate, the Board by resolution may reduce the size of the Board or choose a substitute nominee.

Director Qualifications and Experience

We believe the qualifications, skills, experience and attributes of our directors are consistent with our criteria for the selection of directors and that, collectively, our directors have functioned effectively overseeing management of the Company over the last year.

2025 Proxy Statement 17

GOVERNANCE OF THE COMPANY

Overview

We believe robust governance practices are important not only to our stockholders, but to our customers, employees, suppliers, and other stakeholders. Our corporate governance framework is designed to promote the Company’s long-term success, consistent with our values. The following sections provide an overview of our corporate governance framework, the Board’s role in risk oversight, and other key elements of our program.

Board Leadership Structure

The Board believes one of its primary responsibilities is to evaluate and determine from time to time the appropriate Board leadership structure to provide effective oversight of the Company. The Board evaluates, at least annually, the leadership structure, giving consideration to, among other things, the advantages and disadvantages of a combined chief executive officer and chairman role, the need for a strong, independent oversight function, and the overall governance and operating environment. The Board continues to believe it is appropriate and in the best interest of the Company and our stockholders at this time to designate an independent, non-executive Chairman of the Board.

Non-Executive Chairman

Our Bylaws provide that the Board will designate the Chairperson of the Board from among its members. Our Corporate Governance Guidelines provide further that the Board believes it is in the best interests of the Company and its stockholders for the Board to have the flexibility to determine the best director to serve as Chairman. Following the 2024 Annual Meeting, the Board designated Adm. Donald as our non-executive Chairman of the Board. Adm. Donald has served in this role since April 2020.

Our non-executive Chairman has the following responsibilities as set forth under our Corporate Governance Guidelines:

•chair all Board and stockholder meetings, including executive sessions of the independent directors;

•serve as a liaison between the Chief Executive Officer and the independent directors;

•ensure the quality, quantity and timeliness of the flow of information from management to the Board (although management is responsible for the preparation of materials for the Board, the non-executive Chairman may specifically request the inclusion of certain materials);

•prepare the agendas of the Board meetings and assist the Chair of each standing committee with preparation of agendas for the respective committee meetings, taking into account the requests of other Board and committee members;

•set an appropriate schedule for Board meetings to assure there is sufficient time for discussion of all agenda items;

•along with the Chair of the Governance and Policy Committee, interview all Board candidates and make recommendations to the Governance and Policy Committee and the Board;

•have the authority to call meetings of the Board and meetings of the independent directors; and

•if requested by the Chief Executive Officer, be available for consultation and direct communication with stockholders.

GOVERNANCE OF THE COMPANY

Role of the Board of Directors

We believe the foundation of sound corporate governance is a board of directors whose independence, skills, experience, and judgment enable the Board to oversee management of the Company effectively and provide constructive advice and counsel.

STRATEGY, RISK AND PERFORMANCE

2025 Proxy Statement 19

GOVERNANCE OF THE COMPANY

The Board’s Role in Risk Oversight

As noted above, the Board’s responsibilities include oversight of enterprise risk management, which includes overseeing our system of financial and operational internal controls, our compliance with applicable laws and regulations, data and cybersecurity risks, and our processes for identifying, assessing and mitigating other significant enterprise risks that may affect the Company. To discharge these responsibilities, the Board must understand the significant risks to which the Company is subject. While the Board is charged with mitigating significant enterprise risks that may affect the Company, the Board understands it is neither possible nor prudent to eliminate all risk. Indeed, purposeful, appropriate and managed risk-taking is essential for the Company to be competitive, profitable, and successfully execute its business strategy. The Board in its oversight role seeks to ensure that management is identifying, appropriately managing and mitigating the Company’s significant enterprise risks.

Management has implemented a robust enterprise risk management (“ERM”) program that is designed to identify, assess, manage, and mitigate significant enterprise risks. Our ERM program is managed by an Enterprise Risk Committee, comprised of management from across business units and programmatic and functional disciplines within the Company. The Enterprise Risk Committee is responsible for overseeing the annual enterprise risk assessment process, overseeing development of, and monitoring, enterprise risk mitigation plans, assessing risk correlations, monitoring emerging and evolving risks, and generating data and reports to facilitate management decision-making and the Board’s overall risk oversight function. While the Board and its committees oversee risk management, management is responsible for identifying, assessing, managing, and mitigating risks on a day-to-day basis.

The Board and its committees are responsible for understanding and evaluating the Company's ERM program and its effectiveness. On an annual basis, the Board is briefed by management on the Company’s ERM program, which includes a report on the Company’s annual enterprise risk assessment process, a review of the identified enterprise risks and risk assessments, and assessments of management’s ability to mitigate appropriately the identified enterprise risks. Management also briefs the Board or a Board committee on a periodic basis on individual enterprise risks, which includes a report from management’s risk owner and the related risk mitigation plan. Management seeks to brief the Board on each Tier 1 enterprise risk, which consist of those enterprise risk most likely to significantly impact the Company if they occur, on an annual basis, except those Tier 1 risks that are relatively static (like the risk of hurricane impact and recovery), which generally are briefed on a biennial basis. The Board is updated on an interim basis on any significant changes to the Company’s enterprise risk roster and any other material developments affecting the Company’s ERM program.

The Governance and Policy Committee is responsible for, among other things, (1) developing and recommending to the Board the processes for the Board’s oversight of the Company’s risk management and (2) monitoring the Board’s oversight of risk management. In connection with this responsibility, the Governance and Policy Committee evaluates the enterprise risk roster generated from the Company’s enterprise risk assessment, allocates oversight responsibilities among the full Board and individual standing Board committees, and develops a schedule for briefing enterprise risks among the Board and its committees.

Risks are inherent in the Company’s operations and the pursuit of its strategy, and oversight of risk management is a continuous process. The Board and its committees regularly engage with management in support of a culture of transparency, integrity, and risk awareness. Directors also are encouraged to communicate directly with senior management, which they do on a routine basis.

BOARD AND COMMITTEE OVERSIGHT OF CYBERSECURITY

In response to the increasing risk exposure presented by data and cybersecurity, the Board formed a standing Cybersecurity Committee of the Board in 2019. The Board believes that dedication of a standing committee to cybersecurity facilitates a deeper Board understanding of the Company’s data and cybersecurity risk exposure; the opportunity for Committee members to have a deeper data and cybersecurity knowledge base; and closer Board oversight of the Company’s management and mitigation of data and cybersecurity risks. In addition to the oversight responsibilities described in this section, the Cybersecurity Committee participates with management periodically in a “tabletop” exercise to test the Company’s cybersecurity incident response plan.

20 Huntington Ingalls Industries, Inc.

GOVERNANCE OF THE COMPANY

While the full Board has ultimate responsibility for the oversight of risk management, each of our Board committees assists the Board in its oversight of certain enterprise risks. Each committee periodically reports to the Board with respect to its oversight of these enterprise risks.

Board of Directors The full Board oversees the Company's enterprise risk management processes, and the Board exercises direct oversight of specific enterprise risks not delegated to one of its committees. The committees report to the full Board with updates on their respective areas of designated risk oversight responsibilities.

Board Meetings and Executive Sessions

The Board meets as frequently as necessary to discharge its responsibilities. Regular meetings of the Board are held at least quarterly, and special meetings may be called as necessary or appropriate.

The Board, with no members of management present (including directors who are also officers of the Company), has the opportunity to meet in executive session at each regularly scheduled Board meeting. In addition, our Corporate Governance Guidelines provide that at least one executive session of independent directors will be held each year. The non-executive Chairman presides over the executive sessions. In 2024, the independent directors met in executive session at all five regular Board meetings during the year.

The Audit Committee meets at each of its regular meetings in separate executive sessions with management, our independent auditor, our Vice President of Internal Audit, and with only committee members present.

Director Nomination Process

The Governance and Policy Committee is responsible for recommending director nominees to the Board for election by our stockholders and for identifying and recommending candidates to fill any vacancies that occur on the Board. The Governance and Policy Committee may use a variety of sources to identify candidates, including recommendations from independent directors or members of management, search firms, communications with other persons who may know of suitable candidates to serve on the Board, and stockholder recommendations.

CRITERIA FOR BOARD MEMBERSHIP

The Board believes all director candidates must possess certain fundamental qualifications in addition to specialized skills and experience contributed by individual directors. The Board and the Governance and Policy Committee consider the qualifications of directors and director candidates individually and in the broader context of the Board’s collective skills and experience in light of the current and future needs of the Board.

In evaluating director candidates, the Governance and Policy Committee reviews the candidate’s background, qualifications, and experience. Director candidates must possess the following fundamental qualifications:

•high personal and professional integrity and ethical standards;

•relevant educational and professional background;

•ability to represent the best interests of all stockholders; and

•demonstrated leadership ability and sound judgment.

Prospective directors also must be willing to submit to a background check necessary for a security clearance.

In addition to the minimum qualifications for all director candidates, the Board and the Governance and Policy Committee consider, among other things:

•the business experience, professional background, and particular skills of the candidate most beneficial to service on our Board;

•the personal integrity, judgment, independence, and reputation of the candidate;

•a candidate’s ability to commit sufficient time and attention to Board service; and

•the absence of any potential conflicts of interest with the Company's interests.

As part of the nomination and evaluation process, director candidates are interviewed by the Chairman of the Board, the chair and members of the Governance and Policy Committee and any other members of the Board who express a desire to meet a candidate.

The Governance and Policy Committee considers the size of the Board and the criteria for Board membership set forth above, giving due consideration to any specific skills, background and/or experiences a director candidate may possess, in determining the candidates to recommend to stockholders for election at each annual meeting of stockholders. The Governance and Policy Committee reviews the composition of the Board as a whole and makes director nominee recommendations with a goal of achieving the optimal mix of experience, expertise, skills, specialized knowledge, and other factors.

STOCKHOLDER NOMINATIONS

Stockholders who wish to recommend director candidates for consideration by the Governance and Policy Committee must submit the name, relevant information about the candidate, and an indication of the consent of the proposed nominee in writing to the Corporate Secretary. All director candidates recommended by stockholders are required to meet the criteria for directors described above, and candidates who meet such criteria will be evaluated by the Governance and Policy Committee. In accordance with our Corporate Governance Guidelines, the Governance and Policy Committee will evaluate director candidates recommended by stockholders in the same manner as candidates identified through other means.

2025 Proxy Statement 25

GOVERNANCE OF THE COMPANY

Stockholders who wish to nominate a person for election as a director at an annual meeting must follow the procedures set forth in our Bylaws. Additionally, our proxy access bylaws provide that a stockholder, or group of up to 20 stockholders, that has owned 3% or more of our outstanding common stock continuously for at least three years as of both the date the notice of the proxy access nomination is received by the Company and the record date for the determination of stockholders entitled to vote at the annual meeting may nominate and include in our proxy materials director candidates constituting up to the greater of 25% of the number of directors then in office as of the last day on which a notice of proxy access nomination may be delivered under our proxy access bylaws or two directors. Stockholders who wish to nominate director candidates for inclusion in our proxy materials under our proxy access bylaw provisions must satisfy the requirements set forth in our Bylaws, as described under “Future Stockholder Proposals and Nominations of Directors” in this Proxy Statement. The Board may exclude any Stockholder Nominee from our proxy materials if the Stockholder Nominee or Eligible Stockholder(s) fail to meet the requirements or provide the undertakings set forth in our Bylaws or Corporate Governance Guidelines and for other reasons set forth in our Bylaws. The Board expects to evaluate any director candidates nominated through the proxy access process in the same manner as other director candidates are evaluated.

RETIREMENT POLICY

We have a retirement policy that provides for a director to retire at the annual meeting following the earlier of the director’s 76th birthday or 15 years of service on the Board. Upon the recommendation of the Governance and Policy Committee, the Board may waive either of these requirements as to any director if the Board deems a waiver to be in the best interests of the Company.

In addition to our retirement policy, when a director’s principal occupation or business association changes substantially during his or her tenure as a director, the Board expects the affected director to tender his or her resignation for consideration by the Governance and Policy Committee and the Board, as provided in our Corporate Governance Guidelines.

Board Memberships and Other Relationships

The Board expects directors (as well as any director candidates) to ensure they can commit sufficient time and attention to Board activities. Our objective is for the collective skills, experiences, attributes, and perspectives of Board members to create an outstanding, dynamic, and effective Board and strengthen the Board’s ability to oversee the Company’s business, enhance its performance, and represent the long-term interests of stockholders. All of our non-employee directors are expected to serve on Board committees, supporting the Board’s mission by providing expertise to those committees, and the oversight responsibilities of those committees are considered when evaluating director candidates. The Board and the Governance and Policy Committee also consider other attributes, including the backgrounds and experiences of prospective directors, when selecting director nominees.

Service on Other Boards. In accordance with our Corporate Governance Guidelines, the Board considers the number of boards of other public companies and audit committees of other public companies on which a director candidate serves. Under our Corporate Governance Guidelines, directors should not serve on more than four boards of publicly traded companies, including our Board, and our directors who also serve as chief executive officers or in equivalent positions of other companies should not serve on more than one other board of a publicly traded company, in each case without the approval of the Chairman of the Board. A director who is a full-time employee of our Company may not serve on the board of directors of more than two other publicly traded companies, unless approved by the Board. No member of our Audit Committee may serve on the audit committees of more than three publicly traded companies (including our Company) without the approval of the Board, which must determine annually that such simultaneous service would not impair the ability of the member to effectively serve on our Audit Committee. In 2024, the Board conducted its regular review of directors’ other commitments and determined each director was in compliance with applicable policies.

GOVERNANCE OF THE COMPANY

Director Independence

The Board and the Governance and Policy Committee annually determine whether our directors are independent after reviewing and considering a director’s relevant relationships and arrangements with the Company. Under our Corporate Governance Guidelines, to be considered independent: (i) a director must be independent as determined in accordance with the NYSE Listed Company Manual and (ii) in the Board’s judgment, the director must not have a material relationship with the Company (either directly or as a partner, stockholder, or officer of an organization that has a relationship with the Company).

Our Corporate Governance Guidelines provide that a director may be considered to have a material relationship with the Company if, among other potential considerations, the director:

•has, or has an immediate family member who has, within the prior three years, owned, either directly or indirectly as a partner, stockholder, or officer of another company, more than 5% of the equity of an organization that has a material business relationship with (including as a significant purchaser or supplier of goods or services) the Company; or

•serves as an officer, director, or trustee of a tax exempt organization, and the Company’s discretionary contributions to such organization exceed the greater of $1 million or 2% of that organization’s consolidated gross revenues (excluding any amounts contributed under the Company’s automatic matching of employee charitable contributions).

Ownership of a significant amount of the Company’s stock, by itself, does not constitute a material relationship under our Corporate Governance Guidelines. The Board has considered relevant relationships between the Company and each non-employee director to determine compliance with the independence requirements included in our Corporate Governance Guidelines. Based upon its review, the Board determined that all of the directors, other than Mr. Kastner, are independent. The Board also determined that each current member of the Audit Committee satisfies the additional SEC independence requirements applicable to audit committee members and that each current member of the Compensation Committee satisfies the enhanced independence requirements of the NYSE listing standards.

Board and Committee Evaluations

The Board conducts an annual self-evaluation of the performance of the full Board and delegates to the chairs of the individual Board committees the responsibility to conduct evaluations of the performance of the respective committees. The Board and committees utilize a mix of self-evaluation processes from year to year, including written questionnaires regarding Board and committee matters, individual interviews with directors conducted by the Chairman and/or committee chairs, and director assessments of fellow Board members. In 2024, the Chairman interviewed each Board member as part of the Board’s self-evaluation process with each director receiving in advance potential topics for discussion. The Board, at a later meeting, then reviewed and discussed the observations received from the individual interviews.

Director Education

Our directors are encouraged to attend director continuing education programs periodically. The Board also has adopted an informal policy encouraging each director to attend at least one external director education program on a biennial basis. We make available to the Board a roster of continuing director education programs offered by leading director education organizations, facilitate registrations for directors to attend such programs, and reimburse directors for expenses incurred to attend such programs. In addition to encouraging director attendance at external programs, the Board incorporates a “Board Development” topic into Board meeting agendas on a routine basis. The Board Development topics generally are presented by internal counsel, external counsel, or other experts from outside the Company.

We track the education programs, both external and internal, that individual directors attend, and the Governance and Policy Committee reviews those reports on at least an annual basis.

Code of Ethics and Business Conduct

Our Board of Directors has adopted a Code of Ethics and Business Conduct (the “Code”), which applies to our directors, officers, and employees. It identifies core values, standards, and behaviors that guide our officers, directors, and employees in the discharge of their duties and responsibilities on behalf of the Company. The Code also includes the commitments the Company has made to its employees, customers, stockholders, communities, and suppliers. The Code addresses, among other matters, conflicts of interest, corporate opportunities, trading in Company securities, political contributions, and treatment of confidential information. Employees are required to report any conduct they believe in good faith is an actual or apparent violation of the Code. The Code also includes provisions applicable to our principal executive officer, principal financial officer, principal accounting officer and/or controller, and other persons performing similar functions, as required by SEC rules.

Insider Trading Policy

We have adopted an Insider Trading Policy applicable to the Company’s directors, officers, and employees that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations and the NYSE listing standards. Our Insider Trading Policy states, among other things, that our directors, officers, and employees are prohibited from trading in our securities while aware of material, nonpublic information. The foregoing summary does not purport to be complete and is qualified by reference to our Insider Trading Policy filed as an exhibit to our 2024 Form 10-K.

Communications with the Board

Stockholders and other stakeholders may also communicate with our non-executive Chairman, or specific committee chairs, by writing to one of the emails identified in our Corporate Governance Guidelines. At the direction of the Board, correspondence received may be opened and screened for security purposes.

Communications from stockholders and other stakeholders are distributed to the Board, the applicable Board committee, or an individual director or directors, as appropriate, depending on the facts and circumstances of the communication. The Board has requested that certain items unrelated to the duties and responsibilities of the Board be excluded or redirected, as appropriate, such as: business solicitations or advertisements; junk mail and mass mailings; resumes and other forms of job inquiries; and surveys. In addition, communications that are unduly hostile, threatening, or similarly unsuitable will be excluded. Notwithstanding the foregoing, any communication will be made available to any director upon his or her request.

DIRECTOR COMPENSATION

Our director compensation program for non-employee directors is comprised of both cash retainers and equity awards in the form of either deferred stock units or shares of our common stock and is designed to:

•promote alignment with long-term stockholder interests;

•enable us to attract and retain outstanding directors who meet the criteria described under “Governance of the Company” above;

•recognize the substantial time commitments necessary to oversee HII’s business; and

•support the independence of thought and action expected of directors.

The Compensation Committee reviews annually our non-employee director compensation, with the assistance of its independent compensation consultant, and recommends any changes to the Board for approval. In 2024, at the request of the Compensation Committee, the independent compensation consultant conducted an assessment of the competitive market for outside director compensation against the peer group for our 2024 NEO compensation analysis and determined that our director compensation generally approximates the median for such peer group and the S&P 500 more broadly.

Our compensation programs are: •primarily customer-focused, rewarding safety, quality, cost and schedule performance, and stockholder friendly, rewarding consistent achievement of strong financial results and increasing stockholder value; •designed to influence outcomes and provide a balance between short- and long-term performances; •based on achievement of clear and measurable financial results and accountabilities, with an emphasis on performance-based compensation, and formula-based with appropriate levels of discretion for adjustments; •competitive within the market, with measures oriented to promoting strong improvements in HII’s business results as the predominant factor; •intended to be disclosed and explained in a transparent and understandable manner, with clear and concise goals to enable the assessment of performance by our Compensation Committee and by our stockholders through the CD&A; •designed to produce significant individual rewards for achievement of business goals through both annual operating performance and increased stockholder value and to negatively impact executive compensation for failure to achieve business goals; •intended to promote alignment of management and stockholder interests through establishment of stock ownership requirements and monitoring of related executive compliance; •designed to mitigate excessive risk by emphasizing a long-term focus on compensation and financial performance through the mix of long-term compensation awards, selection of performance criteria and oversight of compensation programs; and •intended to be applied consistently for all incentive plan participants to ensure proper alignment, accountability and line-of-sight regarding commitments and priorities. Recommendation We believe our compensation program, with its balance of base salary, short-term incentives (annual cash incentive awards) and long-term incentives (performance and time-based equity awards), rewards sustained performance that is aligned with long-term customer and stockholder interests. Accordingly, the Board recommends that stockholders approve the following resolution: “RESOLVED, that the stockholders approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure.”
		The Board recommends a vote FOR this Proposal 2.

EXECUTIVE SUMMARY

Our executive compensation program and practices are described in detail over the following pages. We have designed our executive compensation program to attract, motivate and retain highly qualified executives, incentivize our executives to achieve business objectives, reward performance and align the interests of our executives with the interests of our stockholders and customers. The fundamental philosophy of our executive compensation program, set by the Compensation Committee of the Board, is pay for performance. Our compensation program is designed to balance performance-based compensation over the short-term and long-term to incentivize decisions and actions that promote stockholder value and focus our executives on performance that benefits our stockholders and customers, while discouraging inappropriate risk-taking behaviors.

The following charts set forth the percentage of total compensation corresponding to each compensation element received by our CEO and by our other NEOs collectively in 2024.

PAY FOR PERFORMANCE

Our pay for performance philosophy and compensation principles allow us to provide significant reward opportunities to our NEOs linked to the achievement of our financial and operational goals. Above all, these goals are customer-focused, rewarding achievement of safety, quality, cost and schedule goals, and stockholder-friendly, rewarding consistent achievement of strong financial results and building or increasing stockholder value.

This focus on performance is demonstrated in the total targeted compensation mix of our NEOs, which is heavily weighted toward the variable short-term performance-based elements, and toward the long-term and equity-based elements. The following charts set forth the percentage of total target compensation corresponding to each compensation element for our CEO and for our other NEOs collectively for 2024.

2024 NEO KEY COMPENSATION DECISIONS

Key compensation decisions for our NEOs for 2024 included the following:

•All NEOs received performance-based merit increases in their base compensation for 2024. In addition, Mr. Green received a market adjustment based on market data.

•Targets as a percentage of base salary for annual incentive awards for 2024 under our AIP were unchanged from 2023, with the exception of Mr. Kastner, whose target as a percentage of base salary increased from 135% to 145%. Based on our performance for 2024, as well as the individual performances of our NEOs, payout awards to NEOs under our AIP were approved at levels that ranged from 65% to 200% of targets.

•Targets for long-term incentive awards for 2024 were unchanged from 2023. Long-term incentive awards consisted of restricted performance stock rights, which vest only upon achievement of performance metrics measured over a three-year period, and restricted stock rights, which vest on a three-year graded schedule.

2024 BUSINESS HIGHLIGHTS

We are proud of our many achievements in 2024. Ingalls delivered amphibious transport dock Richard M.

COMMITMENT TO COMPENSATION BEST PRACTICES

We highlight below certain executive compensation practices we have implemented to drive performance, as well as certain practices we have avoided as not supportive of the long-term interests of our customers or stockholders.

What we do
Consideration of Annual "Say-on-Pay" Advisory Vote	The Compensation Committee considers the results of the annual stockholder "Say-on-Pay" advisory vote on executive compensation.
Pay for Performance	Our executive compensation program is heavily weighted toward variable, performance-based elements, and toward long-term and equity-based elements. Variable compensation is tied to the achievement of performance goals and includes annual cash incentive awards and long-term restricted performance stock rights, which are described in detail in this CD&A.
Compensation Risk Assessment	We assess the risk of our compensation programs on an annual basis both internally and with the engagement of the Compensation Committee’s independent compensation consultant. The Compensation Committee agreed with the consultant’s report that there was no undue risk associated with the design or delivery of the programs in 2024.
Compensation Recovery Policy	Our Dodd-Frank Compensation Recovery Policy requires us to recover erroneously awarded “incentive compensation” received by certain current or former executive officers or vice presidents of the Company.
Targeted Compensation Benchmarking	HII is a unique business with few direct competitors. The Compensation Committee therefore strikes a balance between internal equity and external benchmarking when setting executive pay levels.
Independent Compensation Consultant	The Compensation Committee engages an independent compensation consultant to assess the market for the determination of our executive compensation elements and performance targets on an annual and ongoing basis.
Executive Stock Ownership Guidelines	Our stock ownership guidelines provide that each NEO must own a multiple of his or her annual base salary in our common stock, and we have instituted holding requirements prohibiting our NEOs from selling HII common stock received as compensation until their stock ownership requirements have been met.

What we don't do
No Employment Agreements for Executives	None of our NEOs have employment agreements, so each NEO is employed by the Company “at will.” We maintain a severance plan that provides for the payment of severance benefits in limited termination circumstances.
No Change-in-Control Agreements for Executives	We have no change-in-control agreements or related executive tax gross-up benefits. The only change-in-control provision in our compensation plans, which applies to all employees who hold equity awards, is the possible acceleration of equity vesting in certain limited circumstances within the parameters of a change-in-control transaction, as defined in the related plans.
No Hedging or Pledging by Officers or Directors	Officers, directors and certain other employees are prohibited from engaging in speculative transactions in our securities, pledging our securities as collateral for a loan or other transaction or engaging in any hedging transactions involving our securities.
No Dividends or Dividend Equivalents Paid on Restricted Performance Stock Rights (“RPSRs”) or Restricted Stock Rights (“RSRs”) Prior to Vesting	Accrued dividend equivalent units earned on RPSRs and RSRs are paid only at the time, and to the extent that, the underlying award vests and is paid.

EXECUTIVE COMPENSATION

EXECUTIVE COMPENSATION PRINCIPLES

The Compensation Committee of the Board (which we refer to as the “Committee” in this CD&A) is comprised exclusively of independent directors, as determined under NYSE corporate governance listing standards, including the enhanced independence standards applicable to members of the Committee. The Committee oversees all of our compensation and benefit programs that affect our NEOs, as well as other officers elected by the Board. The Committee also provides strategic direction for our overall compensation and benefits structure and oversees CEO and executive officer succession plans. In conducting oversight of our compensation and benefit programs, the Committee is guided by the following compensation principles approved by the Committee:

•Our compensation programs will be primarily customer-focused, rewarding safety, quality, cost and schedule performance, and stockholder friendly, rewarding consistent achievement of strong financial results and increasing stockholder value.

•Compensation programs will be designed to influence outcomes and will provide a balance between short- and long-term performances.

•Compensation programs will be based on achievement of clear and measurable financial results and accountabilities, with an emphasis on performance-based compensation, and will be formula-based with appropriate levels of discretion for adjustments.

•Compensation and benefits will be competitive within the market. Alignment with peer companies will be considered when developing programs and goals, but measures oriented to promoting strong improvements in our own business results will be the predominant factor.

•Compensation will be disclosed and explained in a transparent and understandable manner. Clear and concise goals will be established to enable the assessment of performance by the Committee and by stockholders through the CD&A.

•Achievement of business goals through both annual operating performance and increased stockholder value will produce significant individual rewards; failure to achieve business goals will negatively affect the pay of our executives.

•To promote alignment of management and stockholder interests, elected officers will meet stock ownership guidelines in the following multiples of base salary: CEO and President, seven times; all other elected officers reporting to the CEO, three times. The Committee will monitor attainment of the ownership guidelines on an annual basis.

•The mix of long-term awards, selection of performance criteria and oversight of compensation programs, together with other features, such as our stock ownership guidelines, will be designed to discourage excessive risk taking by emphasizing a long-term focus on compensation and financial performance.

•Our NEO compensation strategy will be consistently applied for all incentive plan participants to promote proper alignment, accountability and line-of-sight regarding commitments and priorities.

2024 SAY-ON-PAY ADVISORY VOTE ON EXECUTIVE COMPENSATION

We value the input of our stockholders and annually seek the approval of our stockholders, on an advisory basis, on the compensation of our NEOs. Consistent with our goal of supporting a pay for performance philosophy by implementing compensation programs that reward performance, are market competitive and align the interests of our executives with the interests of our stockholders and customers, we regularly engage with stockholders regarding the design, effectiveness and results of our executive compensation program.

At our 2024 Annual Meeting of Stockholders, our stockholders continued to demonstrate support of our executive compensation program with 96% approval. This strong support, among other factors, resulted in the Committee continuing our executive compensation program without significant changes.

EXECUTIVE COMPENSATION

ROLE OF INDEPENDENT COMPENSATION CONSULTANT

The Committee engages an independent compensation consultant, Exequity (“Compensation Consultant”), to assist the Committee in carrying out its responsibilities under its charter. The Compensation Consultant reports directly to the Committee, and the Committee retains the right to terminate or replace the Compensation Consultant at any time. When directed to do so by the Committee, the Compensation Consultant also works collaboratively with Company management to develop analyses and proposals for presentations to the Committee. The Committee reviews the performance of the independent Compensation Consultant on an annual basis and determines whether to continue the engagement.

The Compensation Consultant regularly attends Committee meetings, and during 2024 presented analyses and key recommendations for Committee consideration, discussed emerging trends and technical issues and reviewed and commented on management’s proposals, as appropriate. In addition, the Compensation Consultant responded to miscellaneous Committee requests.

In accordance with SEC rules and NYSE listing standards, the Committee reviewed and assessed the Compensation Consultant’s independence, including a review of (1) other services provided to us by the consultant; (2) fees paid by us as a percentage of the consulting firm’s total revenue; (3) policies or procedures maintained by the consulting firm designed to prevent a conflict of interest; (4) any business or personal relationships between the individual consultants involved in the engagement and a member of the Committee; (5) any Company stock owned by the individual consultants involved in the engagement; and (6) any business or personal relationships between our executive officers and the consulting firm or the individual consultants involved in the engagement. Based on this review, the Committee concluded that the Compensation Consultant is independent and that the work of the Compensation Consultant did not raise any conflict of interest.

COMPENSATION PEER GROUP

The Committee believes our total compensation program (base salary, target annual cash incentive awards, target long-term incentive awards and benefits) should provide aggregate compensation at approximately the 50th percentile of the relevant market. Based upon an analysis conducted by the Compensation Consultant and reviewed with the Committee, the Committee determined that our NEO base pay generally approximates the median of the peer companies and long-term incentive compensation is generally in the third or fourth quartile among the peer companies. This compensation mix is consistent with both management’s and the Committee’s philosophy that a significant portion of an executive’s overall compensation package should be based on the performance of the Company and therefore be at risk.

HII is a unique business with few directly comparable peer companies. As such, our current peer group is comprised of heavy manufacturing, engineering and defense companies that have annual revenues generally between $2 billion and $20 billion and that most closely match our Company in terms of market cap, strategic interest, workforce similarities and/or business type.

The targeted peer group for our 2024 NEO compensation analysis consisted of the following 16 companies:

Booz Allen Hamilton Holding Corporation	Leidos Holdings, Inc.
BWX Enterprises, Inc.	Moog Inc.
Curtiss-Wright Corporation	Oshkosh Corporation
Dover Corporation	Parker Hannifin Corporation
Howmet Aerospace Inc.	Spirit AeroSystems Holdings, Inc.
Jacobs Engineering Group, Inc.	Teledyne Technologies Incorporated
KBR Inc.	Textron Inc.
L-3 Harris Technologies, Inc.	TransDigm Group

2025 Proxy Statement 41

EXECUTIVE COMPENSATION

HII’s peer group has remained relatively consistent over the past several years, and with respect to peer company revenues, HII approximates the 70th percentile of the group. During the third quarter of 2024, the Compensation Consultant conducted an extensive review of the current peer companies and identified and screened others that may serve as more appropriate peers with respect to both revenues and business alignment going forward. As a result of this review, the Committee decided to modify the Company’s peer group for 2025 by removing BWX Enterprises, Inc., Curtiss-Wright Corporation and Moog Inc. and adding Cognizant Technologies Solutions Corporation, General Dynamics Corporation and Northrop Grumman Corporation. With these changes, our peer group will be comprised of companies that have annual revenues generally between $5 billion and $40 billion, and our relative revenue positioning moves from the 70th percentile to the 50th percentile of the peer group.

COMPENSATION RISK ASSESSMENT

The Board actively oversees our overall risk profile, including the potential risk posed by our compensation programs. During the third quarter of 2024, a risk assessment and analysis of our executive compensation programs was conducted by the Compensation Consultant. Their findings confirmed that our executive compensation programs are designed to drive a pay for performance philosophy and do not create risks that are likely to have a material adverse impact on the Company. The Committee evaluated and discussed the risk analysis with the Compensation Consultant and agreed with the consultant’s conclusions.

The following factors are key components of our executive compensation risk mitigation efforts:

•Our stock ownership guidelines provide a strong risk mitigation tool;

•Our compensation recovery policy applies to our president, principal financial officer, principal accounting officer, any vice president, any other officer who performs a significant policy-making function or any other person who performs similar policy-making functions for the Company, and allows us to recover erroneously awarded incentive compensation;

•Our lack of employment agreements discourages management entrenchment and increases our flexibility to make management changes as necessary;

•Our long-term incentive compensation plan includes a relative performance component, mitigating risk and inherent forecasting uncertainty of relying solely on budget-based goals;

•Long-term incentive compensation payouts are capped at 200%, preventing possible windfall awards resulting from unforeseen circumstances; and

•Long-term performance-based incentive compensation awards are earned over a three-year performance period and reduce any incentive to engage in business tactics that improve short-term performance at the expense of long-term success.

2024 COMPENSATION ELEMENTS

The direct compensation elements for executives under our compensation program consist primarily of base salaries, annual incentive awards, and long-term incentive awards. Annual base salary provides a fixed minimum level of compensation that is competitive within the relevant market and helps us attract and retain highly qualified executives. Annual incentive awards are generally paid in cash and intended to motivate executives to achieve pre-determined annual financial and operational goals that are aligned with our strategic goals. Long-term incentive awards are generally equity-based and intended to promote achievement of pre-determined three-year financial performance goals aligned with long-term stockholder and customer interests. Beginning in 2024, a portion of the long-term equity-based awards are provided in the form of restricted stock rights, which are time-based awards, with ratable vesting that occurs over three years.

ANNUAL INCENTIVE COMPENSATION

The Committee approves annual incentive compensation targets as a percentage of base salary for each NEO position. Targets vary with relevant market benchmarks, individual job level, job scope and overall influence on our business results. The Committee considers both the recommendations of the Compensation Consultant and those of management in determining appropriate annual incentive targets for our NEOs. The target incentive award (“Target Bonus”) is based on a percentage of each NEO’s base salary and provides a basis upon which a final award amount is determined by the Committee based upon its assessment of performance against pre-determined performance criteria after the year has ended. The annual incentive compensation targets for our NEOs expressed as a percentage of base salary tend to fall into the third quartile of the relevant market data. No annual incentive award payout can exceed 200% of an individual’s Target Bonus.

ANNUAL INCENTIVE FORMULA FOR 2024

Corporate NEOs (Messrs. Kastner, Stiehle, and Boudreaux)

The annual incentive award formula for the corporate office for the 2024 performance period was:

Base Salary x Target %  =  Target Bonus

Target Bonus x CPF x IPF  =  Final Bonus Award

1.The Corporate Performance Factor (“CPF”) is capped at 200% and is based on enterprise financial metric goals (Operating Margin (“OM”) and Operating Financial Cash Flow (“OCF”)) (90% weight) and strategic leadership goals (10% weight) as described more fully under 2024 Annual Incentive Plan Goals and Results, below. OM is equal to segment operating income as a percentage of total revenues, Segment operating income is equal to operating income before the Operating FAS/CAS Adjustment and non-current state income taxes. OCF represents cash from operating activities before discretionary pension contributions, capital expenditures and excess cash flow. Strategic leadership goals are based on four strategic metrics: leadership, environmental, social, and governance (“ESG”), cybersecurity, and compliance.

2.The Individual Performance Factor (“IPF”) can range from 0 to 1.5. The IPF for Messrs. Kastner, Stiehle, and Boudreaux for 2024 was 1.0.

2025 Proxy Statement 43

EXECUTIVE COMPENSATION

Division NEOs (Ms. Boykin and Mr. Green)

The annual incentive award formula for the divisions for the 2024 performance period was:

Base Salary x Target %  =  Target Bonus

Target Bonus x DPF x IPF  =  Final Bonus Award

1.The Division Performance Factor (“DPF”) is capped at 200% and is based on division financial metric goals, division non-financial goals and strategic leadership goals. The goals and weightings for Ms. Boykin and Mr. Green are described more fully under 2024 Annual Incentive Plan Goals and Results, below.

2.The IPF can range from 0 to 1.5. The IPF for Ms. Boykin and Mr. Green for 2024 was 1.0.

At the conclusion of each calendar year, our CEO conducts an annual performance evaluation for each NEO as a basis for recommending an IPF score for each NEO. These evaluations are reviewed with the Committee. Each NEO’s individual performance is evaluated based upon the following factors:

•Financial performance of our Company as a whole and the division(s) (where applicable);

•Performance on non-financial goals, including enterprise-wide goals and division-specific operating goals;

•Strategic leadership and vision;

•Program execution and performance;

•Customer relationships; and

•Peer and employee relationships/engagement.

The Committee reviews and considers the recommendations from the CEO and all performance information, including a comparison to the 2024 peer group data. The Committee then approves annual incentive compensation payouts for all NEOs, subject to ratification by the independent members of the Board with respect to the CEO’s compensation.

TARGET BONUS AMOUNTS

Based on analyses of relevant market benchmarks and peer group data, no adjustments were made to the annual incentive compensation targets as a percentage of base salary except for Mr. Kastner. The 2024 Target Bonus amounts were as follows:

Name	Incentive Target as % of Base Salary (%)	2024 Target Bonus    ($)
Christopher D. Kastner(1)	145	1,885,000
Thomas E. Stiehle	80	473,800

Edgar A. Green III	80	452,000

(1)Mr. Kastner’s incentive target as a percentage of base salary was increased in 2024 from 135% to 145%.

2024 ANNUAL INCENTIVE PLAN GOALS AND RESULTS

For the 2024 annual incentive awards, we used a mix of financial and non-financial goals to measure performance. The Committee approved financial metric goals and strategic leadership goals under our AIP for the corporate office, and, for our three operating divisions, financial metrics, operational metrics and strategic leadership goals. AIP goals are plan-based with clear targets connected to our annual operating plan. The AIP goals are based upon metrics that are customer focused and stockholder friendly with clear line-of-sight financial and operational metrics. Operational and strategic leadership goals were developed collaboratively between division management and corporate management.

2025 ANNUAL INCENTIVE PLAN PERFORMANCE METRIC CHANGE

For 2025, the Committee approved several changes to the metrics utilized to measure performance for the annual incentive awards. AIP awards for the year ending December 31, 2025 will be determined based on Company financial performance, strategic leadership performance, and operational performance, which will be determined by the average of the divisions’ operating performance for 2025. In addition, the division AIP metrics for 2025 have been updated to remove operational metrics related to diversity and inclusion, consistent with applicable legal and regulatory requirements.

LONG-TERM INCENTIVE COMPENSATION

Long-term incentive compensation awards in 2024 were granted under our stockholder-approved Huntington Ingalls Industries, Inc. 2022 Long Term Incentive Stock Plan (the “2022 Plan”). All long-term incentive compensation awards granted to our NEOs in 2024 were comprised of 70% Restricted Performance Stock Rights (“RPSRs”) and 30% Restricted Stock Rights (“RSRs”). The Committee determines long-term incentive compensation target values for our NEOs based upon a peer group analysis, applying value-based guidelines that focus on the award value rather than the number of shares granted (share-based guidelines). The Committee believes value-based guidelines more effectively deliver long-term incentive compensation awards that are consistent with awards received by individuals holding comparable positions at peer companies.

Each RPSR and RSR represents the right to receive one share of our common stock, or cash of equivalent value, subject to vesting as provided in the award. The RPSR awards will vest and be distributed following the completion of the performance period beginning January 1, 2024 through December 31, 2026 if goals are met. The RSR awards are time-based only, and vest ratably over a three-year period, with 33 1/3% vesting upon each of the first, second and third anniversaries of the grant date. Dividend equivalent units (“DEUs”) accrue on both RPSR and RSR awards following payment by the Company of a cash dividend on our common stock. These DEUs remain subject to the terms and conditions of the underlying RPSR and RSR grants and are paid only to the extent the underlying RPSRs and RSRs vest.

The Committee and management review and evaluate RPSR performance goals to ensure they are aligned with our long-term objectives. For the 2024 grants, the Committee and management determined that performance for long-term incentive compensation awards to our NEOs would be measured using return on invested capital (“ROIC”), earnings before interest, taxes, depreciation, amortization and pension (“EBITDAP”) and relative EBITDAP growth over the performance period from January 1, 2024 through December 31, 2026. The number of shares that ultimately vest and are issued to an NEO under an RPSR award can vary from 0% to 200% of the original number of shares granted plus accrued dividends.

Metric	Weighting	Rationale	Calculation
Return on Invested Capital	40%	Measures the Company’s ability to use cash flows to generate returns	ROIC is calculated as Adjusted Free Cash Flow divided by Average Invested Capital
EBITDAP	40%	Used as an indicator of the Company’s financial performance	EBITDAP is calculated as Net Earnings, plus interest, taxes, depreciation and amortization, less Net Pension/Post Retirement Benefit/Expense
Relative EBITDAP Growth	20%	Used as an indicator of the Company’s financial performance relative to the S&P Aerospace and Defense Select Index (“SPSIAD”), which consists of more than 30 companies	Relative EBITDAP is calculated as our EBITDAP ending balance less our EBITDAP beginning balance, divided by the EBITDAP beginning balance, measured against EBITDAP growth of the SPSIAD

For 2024, the long-term incentive compensation target values for our NEOs were approved by the Committee as follows:

Name	2024 Long-Term Incentive Compensation Target ($)	Actual Award ($)
Christopher D. Kastner	6,500,000	6,499,823
Thomas E. Stiehle	1,500,000	1,499,604

Jennifer R. Boykin	1,150,000	1,149,572
Edgar A. Green III	1,150,000	1,149,572

The target dollar amounts are grant date theoretical values and not based upon any actual calculation or estimate of payout. An NEO is not guaranteed to receive any payout as a result of the 2024 grants.

2022-2024 LONG-TERM INCENTIVE PLAN RESULTS

During the first quarter of each year, the Committee reviews our financial performance over the prior three years against approved long-term incentive compensation goals to determine payout multiples for RPSRs with a performance period that ended December 31 of the prior year. At the February 2025 meeting, the Committee reviewed performance for the January 1, 2022 through December 31, 2024 performance period for the 2022 RPSR awards granted in February 2022. The performance score for these equity grants, as approved by the Committee, was calculated as follows:

	HII 2022-2024 Goals			Actual Performance (Adj.)
	Goals @ 0%	Goals @ 100%	Goals @ 200%	Performance Results	Score	Weighting		CPF

(4)The EBITDAP and ROIC metrics were adjusted for the performance period to account for certain business conditions that impacted the timing of revenue and cash flows due to the COVID-19 pandemic that were unanticipated at the time the goals were established.

The 2022 RPSR awards paid out at 109% of target, and earned RPSRs were issued on February 24, 2025.

ADDITIONAL BENEFITS

We provide additional benefits to our NEOs through various plans that are also available to some or all of our other employees. Although these plans are not directly overseen by the Committee, the Committee considers benefits under these plans when considering an executive’s total annual compensation and determining the annual and long-term compensation components. These benefits are not performance-related and are designed to provide a market competitive compensation package to attract, motivate and retain the executive talent we need to achieve our business objectives. The plans include broad-based retirement plans, as well as additional supplemental executive benefits, including supplemental pension plans and enhanced health and welfare benefits (dental, life, AD&D and disability).

2025 Proxy Statement 49

EXECUTIVE COMPENSATION

Defined Benefit Retirement Plans. We maintain tax-qualified defined benefit pension plans that cover all but two of our NEOs and the majority of our workforce. These plans are structured to retain and reward employees for long service and to recognize higher performance levels through annual pay increases. Compensation, age and service factor into the amount of the benefits provided under the plans.

We also maintain non-tax-qualified supplemental defined benefit pension plans that cover all but two of our NEOs. These plans provide benefits that would have been provided under the tax-qualified plans if no limits applied to such plans under the Internal Revenue Code (“IRC”). These types of benefits are common in our industry.

Defined Contribution Savings Plans. We maintain tax-qualified defined contribution savings plans that cover our NEOs and the majority of our workforce. Participating employees contribute portions of their pay to the plans, and the Company generally provides a matching contribution.

We also maintain two non-tax-qualified supplemental savings plans that cover all eligible employees, including our NEOs. The Savings Excess Plan (“SEP”) allows eligible employees to defer compensation beyond the IRC limits of the tax-qualified plans and receive a matching Company contribution. Eligibility begins when annual income, including base pay and bonuses, equals or exceeds $345,000, the plan compensation limit under the IRC for 2024. Eligible employees under the IRC may participate in the plan in the calendar year after their total eligible cash income meets or exceeds this limit.

The Officers Retirement Account Contribution Plan (“ORAC”) covers the majority of the Company’s elected and appointed officers hired on or after July 1, 2008, who are not eligible for defined benefit pension plans. Enrollment is automatic, and the Company contributes an amount equal to 4% of the officer’s eligible compensation. Because Messrs. Boudreaux and Green were hired after June 30, 2008, they are not eligible to participate in the Company’s qualified and nonqualified defined benefit pension plans, but they receive the SEP and ORAC benefits described above. Our other NEOs do not receive ORAC benefits. Additional information about the SEP and the ORAC is provided in the Nonqualified Deferred Compensation table.

Perquisites. Our NEOs are eligible for certain executive perquisites, which include financial planning, dental insurance, physical exams, personal liability insurance and relocation benefits. These perquisites are common within our industry and comprise an important component of our total compensation package. Management and the Committee review perquisites and benefits on an annual basis to ensure they are appropriate.

Severance Benefits. Management and the Committee believe severance benefits are appropriate for a reasonable amount of time following certain terminations of employment, including a termination without cause. In addition to providing a severance plan for all employees, we maintain The Severance Plan for Elected and Appointed Officers of Huntington Ingalls Industries. Benefits under this plan for our NEOs include the following:

•Lump Sum Cash Severance Payment—A lump sum equal to one and one half (1.5) times the sum of annual base salary and Target Bonus;

•Extension of Medical and Dental Benefits—The employer portion of medical and dental insurance premiums for a period of 18 months following the date of termination (concurrent with COBRA);

•Financial Planning Reimbursement—Eligible expenses incurred prior to the date of termination and eligible expenses incurred in the year in which the date of termination occurs up to a maximum of $15,000 ($30,000 for the CEO), and any fees incurred in the year following the year in which the date of termination occurs up to a maximum of $15,000 ($30,000 for the CEO);

•Executive Physical Reimbursement—Eligible expenses up to $4,000 incurred through the end of the year of termination; and

•Outplacement Services Reimbursement—Fees incurred within one year after the date of termination (limited to 15% of base salary as of the date of termination).

ADDITIONAL COMPENSATION POLICIES

Total Compensation—Tally Sheet

Management provides the Committee with a total compensation and benefits perspective for each NEO, which includes a tally sheet that captures each element of total compensation and benefits. In conjunction with the Committee’s consideration of NEO compensation compared to the Company’s peer group, this tally sheet ensures that compensation decisions are made within a total compensation framework. The tally sheet provides a broad perspective that covers basic annual compensation components, as well as an annualized value of the benefits and perquisites each NEO receives. Accordingly, the values of nonqualified deferred compensation, outstanding equity awards, health and welfare benefits, pension benefits and perquisites are included.

Tax Deductibility of Pay-Section 162(m)

Section 162(m) of the Internal Revenue Code limits the deductibility of compensation to $1 million each for a public company’s CEO, CFO and next three highest-paid executive officers. In addition to salary, the $1 million annual tax deduction limit applies to the following 2024 awards and payouts to executives subject to Section 162(m): AIP awards and long-term incentive compensation awards granted in 2024, payouts on 2023 AIP awards and payouts on long-term incentive compensation awards granted in 2022.

Grant Date for Equity Compensation Awards

Our annual grant cycle for long-term incentive compensation equity awards occurs simultaneously with annual salary increases and annual incentive compensation awards. We expect this to occur in the first two and one-half months of each year. This timing allows management and the Committee to make decisions on all three compensation elements at the same time to promote a total compensation approach.

STOCK OWNERSHIP GUIDELINES

To promote ownership of our common stock by our executives and alignment of management and stockholder interests, we have adopted stock ownership guidelines that prescribe pre-determined stock ownership levels for certain executives, expressed as a multiple of the executive’s base salary. The stock ownership guidelines prescribe the following ownership levels:

•President and CEO—7 times base salary;

•Elected officers reporting directly to the President and CEO—3 times base salary; and

•Other elected, appointed and other officers—1.5 times base salary.

The ownership guidelines may be satisfied in one or more of the following ways:

•Direct ownership of our common stock;

•Restricted Stock Rights (“RSRs”) (vested or unvested) granted in the form of restricted stock units and issued as part of a long-term incentive compensation award;

•Equivalent shares held in our savings plan (401(k) plan); or

•Equivalent shares held in our Savings Excess Plan.

As of February 28, 2025, the percentage of stock ownership target attained by each NEO was as follows:

Name	Target	% of Target Attained
Christopher D. Kastner	7 x salary	171	%
Thomas E. Stiehle	3 x salary	237	%
Chad N. Boudreaux	3 x salary	253	%
Jennifer R. Boykin	3 x salary	179	%
Edgar A. Green III	3 x salary	160	%

2025 Proxy Statement 51

EXECUTIVE COMPENSATION

STOCK HOLDING REQUIREMENT

Awards granted prior to January 1, 2024 are subject to a holding requirement that requires our NEOs and other officers to hold at least 50% of the total number of shares of our common stock received as compensation until the earlier of (a) the third anniversary of the date such shares are issued or (b) the date that employment terminates due to death or disability. This holding requirement continues upon termination or retirement for a one-year period after separation from the Company and applies to any equity compensation award vesting in that one-year period. The stock holding requirement was eliminated for equity awards granted on or after January 1, 2024.

RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION

In October 2023, the Committee approved the HII Dodd-Frank Compensation Recovery Policy (the “Policy”) relating to recovery of erroneously awarded compensation, as required by NYSE listing standards and SEC rules. The Policy covers our president, principal financial officer, principal accounting officer, any vice president, any other officer who performs a significant policy-making function or any other person who performs similar policy-making functions for the Company (each, a “Covered Person”). The Policy requires recovery by the Company of erroneously awarded “incentive-based compensation” (“IBC”) within the three completed fiscal years preceding the date that either:

•the Company concludes, or reasonably should have concluded, that the Company is required to prepare an accounting restatement; or

•a court, regulator or other legally authorized body directs the Company to prepare an accounting restatement.

IBC includes compensation granted, earned or vested in whole or in part upon attainment of a financial reporting measure. IBC is deemed received in the fiscal year during which the reporting measure is attained, not when the award is granted, vested or paid.

The Policy does not limit the Company’s right to terminate employment of any Covered Person, to seek recovery of other compensation paid to a Covered Person or to pursue other rights or remedies available to the Company under applicable law.

Our prior Policy Regarding the Recoupment of Certain Performance-Based Compensation Payments, which requires reimbursement of all or a portion of any erroneously awarded performance-based short-term or long-term cash or equity incentive compensation payments to an employee at the vice president or more senior position level, continues to apply to erroneous compensation received prior to October 2, 2023.

TRADING RESTRICTIONS AND POLICY AGAINST HEDGING AND PLEDGING

Our Insider Trading Policy prohibits directors, officers, and employees from buying or selling securities of any company while aware of material non-public information about that company, subject to certain limited exceptions involving pre-arranged trading plans, and from providing such material non-public information to any person who may trade on the basis of such information. This policy also prohibits directors, officers and certain other employees from engaging in speculative transactions in Company securities, holding Company securities in a margin account or pledging Company securities as collateral for a loan or other transaction or engaging in any hedging transactions involving Company securities, including zero cost collar transactions and forward sale contracts. Directors, officers, and certain other employees may engage in permitted transactions in our securities only during certain specified periods and after receiving authorization from our Office of the Corporate Secretary. The foregoing summary does not purport to be complete and is qualified by reference to our Insider Trading Policy filed as an exhibit to our 2024 Form 10-K.

EXECUTIVE COMPENSATION

2024 CEO PAY RATIO

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K promulgated under the Securities Exchange Act of 1934, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our CEO. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Companies may apply a variety of different methodologies, assumptions, adjustments and estimates in compliance with Item 402(u) of Regulation S-K; as such, the information provided should not be used as a basis for comparisons between different companies.

For 2024, the annual total compensation of the median employee of our Company was $77,857 and the annual total compensation of our CEO, as reported in the Summary Compensation Table above, was $14,545,636. Based upon this information, the ratio of the annual total compensation of our CEO in 2024, Mr. Kastner, to the median of the annual total compensation of all employees was 187 to 1.

	CEO			Median Employee			Pay Ratio
Summary Total Compensation and Pay Ratio		$	14,553,665		$	77,857		187

Our process for identifying the median of the annual total compensation of all our employees, as well as determining the annual total compensation of our median employee and our CEO, was as follows:

We determined that, as of December 31, 2024, our employee population consisted of approximately 44,258 individuals. For purposes of determining our median employee, we excluded 14 employees located in the United Kingdom and Australia. The remaining workforce (excluding our CEO) was 44,243 employees. This population consisted of our full-time, part-time, temporary and seasonal employees.

Our practice is to perform the median employee analysis each year. December 31, 2024, was selected as the date upon which we would identify the “median employee,” because it allowed us to identify our median employee in a reasonably efficient and economical manner. To identify the median employee, we compared 2024 W-2 taxable Medicare wages (Box 5) as reported to the Internal Revenue Service. This compensation measure was consistently applied to all employees included in the calculation. As a result of our analysis, we identified a new median employee for 2024, we calculated annual total compensation for such employee using the same methodology we use for reporting compensation of our NEOs on the 2024 Summary Compensation Table above. With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of the table.

(3)Mr. Boudreaux was hired in August 2011 and is, therefore, not eligible to participate in any historical defined benefit pension plans, which were closed to new participants in 2008. Mr. Boudreaux does, however, participate in Company sponsored defined contribution plans.

(4)Mr. Green was hired in March 2011 and is, therefore, not eligible to participate in any historical defined benefit pension plans, which were closed to new participants in 2008. Mr. Green does, however, participate in Company sponsored defined contribution plans.

The pension values represent the present values of the benefits expected to be paid in the future. They do not represent actual lump sum values that may be paid from a plan. The amount of future payments is based on the current accrued pension benefit as of December 31, 2024. Pursuant to SEC disclosure rules, (i) the actuarial assumptions used to calculate amounts for this table are the same as those used for our financial statements, and (ii) all pension values are determined assuming the NEO works until the specified retirement age, which is the earliest unreduced retirement age (as defined in each plan).

GENERAL EXPLANATION OF THE PENSION BENEFITS TABLE

Individual employees may be covered by several different pension plans as a result of our history as a division of Northrop Grumman. However, an executive’s total benefit under the pension plans is essentially limited to 60% of his or her final average pay. The accrued tax qualified pension benefit cannot be reduced or taken away under applicable law, so all historical pension plans have been maintained.

Pension plans provide income during retirement, as well as benefits in special circumstances, including death and disability. In general, the plans are structured to reward and retain employees of long service and recognize higher achievement levels through increases in annual pay. The term “qualified plan” generally means a plan that qualifies for favorable tax treatment under IRC Section 401. Savings plans (also known as 401(k) plans) and traditional pension plans are examples of qualified plans. Qualified plans apply to a broad base of employees. The term “nonqualified plan” generally means a plan that is limited to a specified group of management personnel. Our nonqualified plans supplement our qualified plans and (1) provide benefits that would be provided under our qualified plans if there were no limitations imposed by the IRC and (2) provide a minimum level of pension benefits to our executives in recognition of their higher levels of responsibility.

The amounts in the table are based upon the specific provisions of each plan, which are described in more detail below. Two basic types of pension benefits are reflected in the Pension Benefits table: traditional benefits and cash balance benefits. For purposes of computing amounts in the table, traditional benefits are determined based on the annual pension earned as of December 31, 2024, and include any supplemental payments. Cash balance benefits are based upon the account balance as of December 31, 2024, plus a future interest credit, converted to an annuity using the applicable conversion factors.

Messrs. Stiehle and Kastner participate in the Huntington Ingalls Industries Retirement Plan “B” and the Huntington Ingalls Industries Supplemental Plan 2—ERISA Supplemental Program 2 (“ERISA 2”). Ms. Boykin participates in the HII Newport News Shipbuilding Inc. Retirement Plan and the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan. Messrs. Boudreaux and Green participate in the Huntington Ingalls Industries Officers Retirement Account Contribution Plan (“ORAC”). Each NEO, except Messrs. Boudreaux and Green, also participates in the Officers Supplemental Executive Retirement Program (“OSERP”).

Effective December 31, 2014, the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan was consolidated with other nonqualified defined benefit pension plans to form the Huntington Ingalls Industries Omnibus Supplemental Retirement Plan. The consolidation does not affect the benefit amounts payable to the participants. Effective December 31, 2019, the Huntington Ingalls Industries Officers Supplemental Executive Retirement Program (the “OSERP”) and Huntington Ingalls Industries Supplemental Plan 2—ERISA 2 were merged into the Huntington Ingalls Industries Omnibus Supplemental Retirement Plan, which was subsequently renamed the Huntington Ingalls Industries Consolidated Supplemental Retirement Plan. This merger does not affect the benefit amounts payable to the participants.

The changes in pension values shown in the Summary Compensation Table include the effects of:

•an additional year of service from December 31, 2023 to December 31, 2024;

•changes in eligible pension pay;

•changes in applicable pay cap limits; and

•changes in actuarial assumptions.

DESCRIPTION OF QUALIFIED PLANS

Huntington Ingalls Industries Retirement Plan “B” and HII Newport News Shipbuilding Inc. Retirement Plan. The general benefit structure for each participant is similar except for the historical benefit formulas, the transition benefit formulas and the timing of the transition period, all of which are described below. The plans are qualified under IRC Section 401 and provide up to three component pieces of benefits depending on when a participant is hired and terminates. The following chart illustrates the component pieces (described in more detail after the chart):

Part A Benefit under the historical plan formula before the transition period		Part B (5-Year Transition Benefit) Benefit based on a formula similar to the one under the historical plan formula during the transition period		Part D Benefit under the cash balance formula after the transition period		Pension Benefit
	+	or (if greater)	+		=
		Part C (5-Year Transition Benefit) Benefit under the cash balance formula during the transition period

The components are the historical benefit (the Part A benefit), the transition benefit (the greater of the Part B benefit or the Part C benefit) and the cash balance benefit (the Part D benefit). Eligible employees who joined a plan after the transition date associated with their pension plan accrue only the cash balance benefit (Part D) from their first date of participation.

The qualified benefit for each NEO is the sum of these three benefits (Part A + Max (Part B or C) + Part D). The transition period for the Huntington Ingalls Industries Retirement Plan “B” was July 1, 2003 through June 30, 2008, while the transition period for the HII Newport News Shipbuilding Inc. Retirement Plan was January 1, 2004 through December 31, 2008. During the transition period, each eligible participant earned the greater of (i) the benefit calculated under a formula similar to his or her historical plan (Part B) or (ii) the cash balance formula benefit (Part C).

The cash balance formula (Parts C and D benefits) uses a participant’s points (age plus years of service) to determine a pay-based credit amount (a percentage of eligible pay) on a monthly basis. Interest is credited monthly on the amount in the participant’s hypothetical individual account. At normal retirement age, a participant’s balance in the hypothetical account is converted into an annuity payable for life, using specified factors. There are various forms of annuities from which the participant can choose, including a single-life annuity or a joint-and-survivor annuity.

Specific Elements of the Plans. The following paragraphs describe specific elements of the qualified plans in which our NEOs participate.

•Formulas Under Historical Plans:

•HII Newport News Shipbuilding Inc. Retirement Plan—This plan provides a benefit equal to 55% of final average pay (as limited by IRC Section 401(a)(17)) multiplied by benefit service up to a maximum of 35 years divided by 35. Participants with pre-1997 service also have a frozen accrued benefit with the prior NNS parent company, Tenneco. Total benefit service is used for the plan benefit, but the frozen accrued benefit with Tenneco is offset from the total benefit. Final average pay is the average of the final 60 months of base pay multiplied by 12 to determine an annual final average pay. Ms. Boykin has historical (Part A) benefits under this formula.

•HII Northrop Grumman Retirement Plan—This plan is a legacy part of the Huntington Ingalls Industries Retirement Plan “B” and provides a benefit equal to 1.6667% of final average pay (as limited by IRC Section 401(a)(17)) multiplied by benefit service up to a maximum of 30 years. Final average pay is the average of the three highest-paid years during which the participant was an eligible employee of Northrop Grumman after 1996. Mr. Kastner has historical (Part A) benefits under this formula.

60 Huntington Ingalls Industries, Inc.

EXECUTIVE COMPENSATION

•HII Grumman Pension Plan—This plan is a legacy part of the Huntington Ingalls Industries Retirement Plan “B” and provides a benefit equal to 1.6667% of final average pay (as limited by IRC Section 401(a)(17)) multiplied by benefit service after December 31, 1994, plus the frozen accrued benefit as of December 31, 1994. Final average pay is the average of the three highest-paid years during which the participant was an eligible employee of the Company after 1996. Messrs. Stiehle and Kastner have historical (Part A) benefits under this formula.

•Cash Balance Formula. Table 1 shows the percentage of pay credit specified at each point level for the Part C benefit for each NEO. Interest is credited monthly based upon the 30-year Treasury bond rate in effect four months prior to the crediting month.

•For the Part D benefit, the cash balance formula for each NEO is based upon Table 2. Interest is credited monthly based on the 30-year Treasury bond rate in effect four months prior to the crediting month.

	Credit Amount
Points (attained age and total service)	All Eligible Pay (%)	Eligible Pay in Excess of Social Security Wage Base (%)

55 to 64	5.5	4.0
65 to 74	6.5	4.0
75 to 84	7.5	4.0
Over 84	9.0	4.0

•Vesting. Participants vest in their program benefits upon completion of three years of service. As of December 31, 2024, each NEO participating in a qualified pension plan has a non-forfeitable right to receive retirement benefits, which are payable upon early (if eligible) or normal retirement, as elected by the NEO.

•Form of Benefit. The standard form of benefit is an annuity payable for the life of the participant. At normal retirement, the annuity for the cash balance formula is equal to the accumulated account balance divided by 9. Other annuity options may be elected; however, each option is actuarially equivalent in value to the standard form.

2025 Proxy Statement 61

EXECUTIVE COMPENSATION

•Pay. Pay for purposes of the cash balance, the HII Grumman Pension Plan formula and the HII Northrop Grumman Retirement Plan formula is primarily salary plus the annual cash bonus. Final average pay for the HII Newport News Shipbuilding Inc. Retirement Plan is determined using base salary only. Pay is limited by IRC Section 401(a)(17).

•Normal Retirement. Normal retirement means the benefit is not reduced for early commencement. It is generally specified in each formula as: age 65 for the HII Grumman Pension Plan, the HII Northrop Grumman Retirement Plan and the HII Newport News Shipbuilding Inc. Retirement Plan formulas and the later of age 65 and three years of vesting service for the cash balance formula.

•Early Retirement. Early retirement eligibility for the historical HII Newport News Shipbuilding Inc. Retirement Plan, HII Grumman Pension Plan (post-1994 benefits), the HII Northrop Grumman Retirement Plan and the cash balance formulas occurs when the participant both attains age 55 and completes ten years of service. Early retirement eligibility for the historical HII Grumman Pension Plan (pre-1995 benefits) occurs when the participant attains age 60 with at least one year of service or age 50 with at least 20 years of service. Early retirement benefits under both the historical and cash balance formulas may be reduced for commencement prior to normal retirement to reflect the longer period of time over which the benefit will be paid.

Messrs. Stiehle and Kastner and Ms. Boykin have reached the age of 55 and have completed ten or more years of service. Mr. Stiehle has reached the age of 50 and completed 20 years of service. Accordingly, each of Messrs. Stiehle and Kastner and Ms. Boykin are eligible for early retirement under the Huntington Ingalls Industries Retirement Plan “B” (which includes historical benefits from the HII Grumman Pension Plan and the HII Northrop Grumman Retirement Plan) or the HII Newport News Shipbuilding Inc. Retirement Plan, as applicable. Early retirement benefits for each NEO cannot commence prior to termination of employment. Messrs. Boudreaux and Green do not participate in any defined benefit pension plans.

DESCRIPTION OF NONQUALIFIED PLANS

Huntington Ingalls Industries Supplemental Plan 2—ERISA Supplemental Program 2. This plan is a nonqualified plan that provides benefits that would have been paid under the Huntington Ingalls Industries Retirement Plan “B” but for the IRC Section 401(a)(17) limit on the amount of compensation that must be taken into account under a qualified plan. The definition of compensation under this plan also includes compensation under deferred compensation plans. Benefits under this plan are subject to a general limitation of 60% of final average pay (reduced for early retirement, if applicable, according to the rules of the OSERP) for all Company pension benefits. Optional forms of payment are generally the same as those from the qualified plan, plus a 13-month delayed lump sum option on a portion of the benefit. Reductions for early retirement apply in the same manner as under the associated qualified plan.

Messrs. Stiehle and Kastner began participating in the plan when they reached applicable pay grades for inclusion in the plan.

HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan. This plan is a nonqualified plan that provides benefits that would have been paid under the HII Newport News Shipbuilding Inc. Retirement Plan but for the IRC Section 401(a)(17) limit on the amount of compensation that must be taken into account under a qualified plan and the IRC Section 415 limit on benefits that may be paid under a qualified plan. The definition of compensation under this plan also includes compensation under deferred compensation plans. Benefits under the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan are subject to a general limitation of 60% of final average pay (reduced for early retirement, if applicable, according to the rules of the OSERP for all pension benefits). Optional forms of payment are the same as those under the HII Newport News Shipbuilding Inc. Retirement Plan. Reductions for early retirement apply in the same manner as under the HII Newport News Shipbuilding Inc. Retirement Plan.

Ms. Boykin began participating in the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan when she reached applicable pay grades for inclusion in the plan.

Officers Supplemental Executive Retirement Program. The OSERP is a nonqualified plan frozen to new entrants on July 1, 2008. Accordingly, officers hired on or after this date and any promoted officers who do not participate in a qualified defined benefit pension plan are not allowed to participate in the program. On December 31, 2018, this program was also closed to those officers whose hire date was prior to July 1, 2008, but promotion date occurred on or after January 1, 2019. Instead, officers who were hired on or after July 1, 2008, or promoted on or after January 1, 2019, participate in the Huntington Ingalls Industries Officers Retirement Account Contribution Plan, which is a defined contribution plan arrangement.

62 Huntington Ingalls Industries, Inc.

EXECUTIVE COMPENSATION

Messrs. Stiehle and Kastner and Ms. Boykin participate in the Huntington Ingalls Industries Officers Supplemental Executive Retirement Program, which provides a total pension benefit equal to a percentage of final average pay (the average pay without the IRC Section 401(a)(17) limit and including deferred compensation in the three highest-paid plan years during the greater of (i) the last ten consecutive years of participation or (ii) all consecutive years of participation since January 1, 1997) where the percentage is determined by the following formula: 2% for each year of service up to ten years, 1.5% for each subsequent year up to 20 years and 1% for each additional year over 20 and less than 45, less any other HII pension benefits. Under the OSERP, all years of service with HII are used to determine the final percentage.

The OSERP benefit, when combined with all HII pension benefits, cannot exceed the general limit of 60% of final average pay (reduced for early retirement, if applicable, according to the rules of the OSERP). Optional forms of payment are generally the same as those under the qualified plan, plus a 13-month delayed lump sum option on a portion of the Huntington Ingalls Industries Officers Supplemental Executive Retirement Program benefit.

•Normal Retirement: Age 65.

•Early Retirement: Age 55 and completion of ten years of service. Benefits are reduced by the lesser of 2.5% for each year between retirement age and age 65, or 2.5% for each point less than 85 at retirement. Points are equal to the sum of age and years of service.

•Vesting: Participants vest in their OSERP benefits upon attaining age 55 and completion of ten years of service or attaining age 65 and completion of five years of service. These milestones must be attained prior to termination from HII.

Huntington Ingalls Industries Consolidated Supplemental Retirement Plan. Effective December 31, 2014, the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan was consolidated with other nonqualified defined benefit pension plans to form the Huntington Ingalls Industries Omnibus Supplemental Retirement Plan. The consolidation does not affect the benefit amounts payable to the participants. Effective December 31, 2019, the OSERP and ERISA 2 were merged into the Huntington Ingalls Industries Omnibus Supplemental Retirement Plan, which was subsequently renamed the Huntington Ingalls Industries Consolidated Supplemental Retirement Plan. This merger does not affect the benefit amounts payable to the participants.

Section 409A Restrictions on Timing and Optional Forms of Payment. Under IRC Section 409A, employees who participate in Company-sponsored nonqualified plans, such as the HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan, the Huntington Ingalls Industries Supplemental Plan 2—ERISA Supplemental Program 2 and the OSERP are subject to special rules regarding the timing and forms of payment for benefits earned or vested after December 31, 2004 (“post-2004 benefits”). Payment of post-2004 benefits must begin on the first day of the month coincident with or following the later of attainment of age 55 and termination from the Company. The optional forms of payment for post-2004 benefits are limited to a single life annuity or a selection of joint and survivor options.

Specific Assumptions Used to Estimate Present Values. The following assumptions were used to estimate the present values in the Pension Benefits table:

•Assumed Retirement Age: For all plans, pension benefits are assumed to begin at the earliest retirement age that the participant can receive an unreduced benefit payable from the plan. OSERP benefits are first unreduced once an NEO reaches age 55 and accumulates 85 points or reaches age 65. HII Newport News Shipbuilding Inc. Retirement Plan and associated HII Newport News Shipbuilding Inc. Retirement Restoration Plan benefits (Part A and B benefits) are first unreduced at the earlier of age 62 and completion of ten years of service or age 65. For the HII Grumman Pension Plan (pre-1995 benefits), vested benefits are first unreduced at age 60. For the HII Grumman Pension Plan (post-1994 Part A and Part B benefits), the HII Northrop Grumman Retirement Plan (Part A and B benefits) and the associated Huntington Ingalls Industries Supplemental Plan 2—ERISA Supplemental Program 2 (Part A and B benefits), vested benefits are first unreduced once an NEO reaches age 55 and accumulates 85 points or reaches age 65. Given each NEO’s period of service, cash balance benefits (Part C and D benefits) will be converted to an annuity on an unreduced basis starting at age 55.

2025 Proxy Statement 63

EXECUTIVE COMPENSATION

When portions of an NEO’s benefit under the “Part A + Max (Part B or Part C) + Part D” structure have different unreduced retirement ages, the later unreduced age is used for the entire benefit.

•Discount Rate: The applicable discount rates are as follows:

Plan Name	12/31/2024 (%)	12/31/2023 (%)
Huntington Ingalls Industries Supplemental Plan 2	5.91	5.26
Huntington Ingalls Industries Retirement Plan “B”	5.94	5.27
HII Newport News Shipbuilding Inc. Retirement Plan	5.98	5.26
HII Newport News Shipbuilding Inc. Retirement Benefit Restoration Plan	5.91	5.26
Officers Supplemental Executive Retirement Program	5.91	5.26

•Mortality Table: A variation of the Pri-2012 and MP-2021 mortality tables, adjusted to reflect the Company’s experience and expectations.

•Present Values: Present values are calculated using the Assumed Retirement Age, Discount Rate and Mortality Table described above; they assume no pre-retirement mortality, disability or termination and that the NEO remains employed until his or her earliest unreduced retirement age.

•Future Investment Crediting Rate Assumption: Cash balance amounts are projected to the Assumed Retirement Age based on the future investment crediting rate assumptions of 3.58% as of December 31, 2023, and 3.54% as of December 31, 2024. These rates are used in conjunction with the discount rate to estimate the present value amounts for cash balance benefits.

Information on Executives Eligible to Retire. Messrs. Stiehle and Kastner and Ms. Boykin are eligible to retire early and begin pension benefits immediately under all plans in which they participate. Their total annual immediate benefit, assuming they had terminated on December 31, 2024, is $722,204 for Mr. Stiehle, $1,561,042 for Mr. Kastner and $559,373 for Ms. Boykin.

•Mr. Green’s aggregate SEP account balance includes $822,353 in employee contributions.

Deferred Compensation Plans and Descriptions

The material terms of the deferred compensation plans in which our NEOs participate are summarized below:

•The “Savings Excess Plan” allows eligible employees to defer between 1% and 75% of salary and annual incentive payments above the limits mandated by the IRS. The Company may provide a matching contribution of up to 4%, based upon a participant contribution rate of 8%. Participants are immediately 100% vested in their accounts and are allowed to make elections regarding how their account balances will be deemed invested for purposes of crediting earnings to the account by selecting investments from a limited list of investment options selected by the plan administrator. No above market earnings are provided under the plan. Based upon an advance election, payment is made in a lump sum or installments over a period of up to 15 years. Neither in-service distributions nor hardship withdrawals are allowed under this plan.

•The “ORAC” covers the majority of those elected and appointed officers hired on or after July 1, 2008, who are not eligible for defined benefit retirement plans. Enrollment is automatic, and the Company contributes an amount equal to 4% of the officer’s eligible compensation.

All deferred compensation that was not earned and vested before January 1, 2005 is subject to the requirements of IRC Section 409A. Those requirements largely restrict an executive’s ability to control the form and timing of distributions from nonqualified plans such as those listed above.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

The tables below provide estimated payments and benefits that we would have provided each NEO if his or her employment had terminated on December 31, 2024, for specified reasons. This information is based upon the assumption that employment terminated on December 31, 2024, and uses the closing price of our common stock of $188.97 on the NYSE as of December 31, 2024. These payments and benefits are provided under the following plans:

•The Severance Plan for Elected and Appointed Officers

•The 2012 Long-Term Incentive Stock Plan and 2022 Long-Term Incentive Stock Plan and terms and conditions of equity awards

We summarize below these plans before providing the estimated payment and benefit amounts in the tables. Due to the many factors that affect the nature and amount of any benefits provided upon the termination events discussed below, any actual amounts paid or distributed to our NEOs may be different. Factors that may affect these amounts include timing during the year of the occurrence of the event, our stock price and the NEO’s age.

2025 Proxy Statement 65

EXECUTIVE COMPENSATION

The amounts described in the tables below are in addition to each NEO’s benefits described in the Pension Benefits and Nonqualified Deferred Compensation tables, as well as benefits generally available to our employees such as distributions under our 401(k) plan, disability and life insurance benefits and accrued vacation.

SEVERANCE PLAN

Upon a “qualifying termination” (defined below), we have discretion to provide severance benefits to our NEOs under The Severance Plan for Elected and Appointed Officers of Huntington Ingalls Industries (the “Severance Plan”). Provided the NEO signed a release, such executive would have received:

•a lump sum severance benefit equal to 1.5 times base salary and target bonus;

•continued medical and dental premium payments for 18 months following the date of termination;

•financial planning expense reimbursement for fees incurred in the year in which the date of termination occurs ((limited to $15,000) ($30,000 for the CEO)) and any fees incurred in the year following the year in which the date of termination occurs ((limited to $15,000) ($30,000 for the CEO));

•reimbursement for the cost of a qualified executive physical as part of the executive perquisites program within established limits (up to $4,000 ) through the end of the year of termination; and

•outplacement services reimbursement for fees incurred within one year after the date of termination (limited to 15% of base salary as of the date of termination).

A “qualifying termination” means one of the following:

•an involuntary termination of employment of the NEO, other than termination for cause or mandatory retirement; or

•an NEO’s election to terminate employment with us in lieu of accepting a downgrade to a non-officer position or status.

TERMS OF EQUITY AWARDS UNDER THE 2012 PLAN AND THE 2022 PLAN

The terms of equity awards to our NEOs under the 2012 Plan and the 2022 Plan provide for prorated or accelerated vesting if an NEO terminates for certain reasons. For RPSRs, accelerated vesting of a portion of each award occurs upon a termination due to death, disability or retirement (after age 55 with ten years of service or mandatory retirement at age 65). For RSRs, accelerated vesting occurs upon a termination due to death or disability.

For purposes of estimating the payments due under RPSRs below, our performance is assumed to be at target levels through the close of each three-year performance period, and we include accrued DEUs for awards granted in 2012 and later.

The terms of equity awards to our NEOs under the 2012 Plan and the 2022 Plan also provide for accelerated vesting of RPSRs and RSRs in the event that the NEO is terminated in a qualifying termination related to a change in control (see “Change-in-Control Followed by Termination Payments Summary” below).

Payouts of RPSRs for retirements and terminations is made during the normal process for payouts, which occurs during the first quarter following the end of the performance period.

(5)Cumulative total shareholder return (“TSR”) is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the Company’s share price at the end and the beginning of the measurement period by the Company’s share price at the beginning of the measurement period.

(6)Represents the peer group TSR, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The peer group used for this purpose is the following published industry index: S&P Aerospace & Defense Select Industry Index.

(7)The dollar amounts reported represent the amount of net income reflected in the Company’s audited financial statements for the applicable year.

(8)EBITDAP is calculated as net earnings, plus interest, taxes, depreciation and amortization, less net pension/post retirement benefit expense. While the Company uses numerous financial and non-financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that EBITDAP is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance.

FINANCIAL PERFORMANCE MEASURES

As described in greater detail under “Compensation Discussion and Analysis” above, HII’s executive compensation program reflects a variable pay for performance philosophy. The metrics we use for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase the value of our enterprise for our stockholders. The most important financial performance measures we used to link executive compensation actually paid to our NEOs, for the most recently completed fiscal year, to our performance are as follows:

•EBITDAP

•Segment operating margin

•Operating cash flow

•Return on invested capital

ANALYSIS OF THE INFORMATION PRESENTED IN THE PAY VERSUS PERFORMANCE TABLE

As described in more detail under “Compensation Discussion and Analysis” above, HII’s executive compensation program reflects a variable pay for performance philosophy. While we utilize several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, HII generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, we are providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

PROPOSAL 3	Ratification of Appointment of Independent Auditor The Audit Committee has selected Deloitte & Touche LLP (“Deloitte”), an independent registered public accounting firm, as our independent auditor to audit the Company’s consolidated financial statements and internal control over financial reporting for the year ending December 31, 2025. Deloitte has served as our independent registered since 2011. The Audit Committee is responsible for appointing, compensating, retaining, overseeing, and discharging (if necessary) the independent auditor. The Audit Committee also is responsible for evaluating, at least annually, the independent auditor’s qualifications and performance, including a review and evaluation of the lead partner. Although ratification of our selection of Deloitte & Touche LLP is not required by our Bylaws or otherwise, we are asking our stockholders to do so as a matter of sound corporate governance. If the selection of Deloitte & Touche LLP is not ratified, the Audit Committee will consider this input in its selection of an auditor for the following year. Representatives of Deloitte will attend the Annual Meeting and will have an opportunity to make a statement and respond to questions, as appropriate.
		The Board recommends a vote FOR this Proposal 3.

Audit Fees and All Other Fees

PROPOSAL 3—RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITOR

Audit Committee Pre-Approval Policies and Procedures

All 2024 services provided by Deloitte & Touche LLP were approved by the Audit Committee. The Audit Committee also reviewed these services to ensure compatibility with maintenance of the auditor’s independence.

The Audit Committee has a pre-approval policy and procedures related to the provision of services by our independent auditor. Under the policy and procedures, the Audit Committee pre-approves both the type of services to be provided by our independent auditor and the estimated fees related to those services. During the approval process, the Audit Committee considers the impact of the types of services and the related fees on the independence of the auditor. The services and fees must be deemed compatible with the maintenance of the auditor’s independence, including compliance with SEC rules and regulations.

The Audit Committee must approve any fees for audit and non-audit services that exceed by certain amounts the estimates of fees for such services initially approved. The Audit Committee is advised quarterly in any event on the services performed by and fees paid to the independent auditor year-to-date for the fiscal year.

Audit Committee Report

As described more fully in its charter, among the purposes for which the Audit Committee was organized are to assist the Board in its general oversight of (a) the integrity of the Company’s financial statements and the Company’s accounting and financial reporting processes and financial statement audits and (b) the Company’s system of internal control over financial reporting. The Audit Committee serves a Board-level oversight role in which it provides advice, counsel and direction to management, the internal audit department and our independent auditors on the basis of information the committee receives, communications with management, the Vice President of Internal Audit and the independent auditors and the experience of the Audit Committee members in business and financial and accounting matters.

In discharging its oversight role, the Audit Committee reviewed and discussed the audited financial statements contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 with management, including our Vice President of Internal Audit, and our independent auditors. Management is responsible for the financial statements and the reporting process, including the system of disclosure controls and procedures and internal control over financial reporting. The independent auditors are responsible for expressing an opinion on the conformity of the financial statements with accounting principles generally accepted in the United States and on the effectiveness of the Company’s internal control over financial reporting.

The Audit Committee met privately with our independent auditors and discussed issues deemed significant by the independent auditors, and the Audit Committee has discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC.

In addition, the Audit Committee discussed with our independent auditors their independence from HII and its management; received the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent auditors’ communications with the Audit Committee concerning independence.

Based on the reviews and discussions described above, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2024.

PROPOSAL 4	Elimination of Personal Liability of Officers for Monetary Damages for Breach of Certain Fiduciary Duties as Permitted by Delaware Law The Board approved and declared advisable, subject to stockholder approval, an amendment (“Exculpation Amendment”) to our Restated Certificate of Incorporation (“Certificate of Incorporation”) to provide for the elimination of personal liability of certain officers for monetary damages for breach of certain fiduciary duties, to the extent permitted by the Delaware General Corporation Law (“DGCL”). We are asking stockholders to approve this Exculpation Amendment, as set forth in Exhibit A to this Proxy Statement.
		The Board recommends a vote FOR this Proposal 4.

Background

Our Certificate of Incorporation currently provides for the elimination of the monetary liability of directors to the fullest extent permitted by Section 102(b)(7) of the DGCL. Effective August 2022, Section 102(b)(7) of the DGCL was amended to permit Delaware corporations to include in their certificates of incorporation provisions limiting the monetary liability of the following officers for breach of the duty of care in certain actions: (1) a corporation’s president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer, or chief accounting officer; (2) an individual identified in the corporation’s SEC filings as one of its most highly compensated officers; and (3) an individual who, by written agreement with the corporation, has consented to be identified as an officer for purposes of Delaware’s long-arm jurisdiction statute.

Consistent with Section 102(b)(7) of the DGCL, the Exculpation Amendment would only eliminate the monetary liability of these officers for breaches of the fiduciary duty of care for direct claims. The Exculpation Amendment would not limit the officer’s liability in any derivative action brought by or on behalf of the Company, such as derivative claims by stockholders on behalf of the Company for breach of the fiduciary duty of care. Like the current provisions on the limitation of liability of directors, the Exculpation Amendment also would not limit the liability of these officers for: (1) any breach of the duty of loyalty to the Company or its stockholders, (2) any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, (3) any transaction from which the officer derived an improper personal benefit, or (4) any action by or in the right of the corporation. The Exculpation Amendment provides that, if the DGCL is amended in the future to authorize further limitation of the liability of officers, then the liability of these officers will be limited to the fullest extent permitted by the DGCL, as so amended.

The Exculpation Amendment is Narrowly Tailored and Enhances Our Ability to Attract and Retain Key Officers

The Board is committed to good corporate governance practices, giving consideration to developments in the law and emerging trends and best practices, and has determined that the Exculpation Amendment is in the best interests of the Company and its stockholders.

The Board aims to ensure that our officers are appropriately protected when acting in the best interest, and on behalf, of the Company. The Exculpation Amendment, which aligns with the exculpation provisions currently available to our directors, enhances our ability to attract and retain key officers by mitigating the risk of personal financial claims that could arise as an officer of the Company while also being narrowly tailored to limit the types of claims for which monetary liability would be limited.

PROPOSAL 4—ELIMINATION OF PERSONAL LIABILITY OF OFFICERS FOR MONETARY DAMAGES FOR BREACH OF CERTAIN FIDUCIARY DUTIES AS PERMITTED BY DELAWARE LAW

Process for Approval of Exculpation Amendment

If stockholders approve the Exculpation Amendment at the Annual Meeting, we intend to file with the Secretary of State of the State of Delaware a certificate of amendment to our Certificate of Incorporation that reflects the Exculpation Amendment shown on Exhibit A, which will be effective upon filing. Stockholder approval of the Exculpation Amendment shown on Exhibit A also will be deemed to constitute the approval of the filing of the certificate of amendment. The Board retains the discretion to abandon, and not implement, the Exculpation Amendment at any time before it becomes effective, even if it is approved by our stockholders. The description of the Exculpation Amendment is qualified in its entirety by, and should be read in conjunction with the full text of, the proposed Exculpation Amendment, which is attached hereto and reflected in Exhibit A.

PROPOSAL 5	Amend Restated Certificate of Incorporation to Conform with Special Meeting Bylaw The Bylaws of the Company provide, among other things, that special meetings of the stockholders of the Company shall be called by the Board (or an authorized committee thereof) or the Chairperson of the Board following the receipt by the Secretary of written requests to call the meeting from the holders of at least 20% of the voting power (the “Required Percentage”) of the outstanding capital stock of the Company (the “Voting Stock”) that have delivered such requests in accordance with the terms of the Bylaws. The Board approved and declared advisable an amendment (“Special Meeting Amendment”) to Article Twelfth of the Certificate of Incorporation to conform with the Special Meeting bylaw provisions governing the ability of stockholders to call a special meeting. We are asking stockholders to approve this Special Meeting Amendment, as set forth in Exhibit B to this Proxy Statement.
		The Board recommends a vote FOR this Proposal 5.

Background

Article Twelfth of the Certificate of Incorporation currently provides that, subject to the terms of any class or series of Preferred Stock, special meetings of the stockholders of the Company may be called only by the Board (or an authorized committee thereof) or the Chairperson of the Board.

In 2016, the Board approved amendments to the Bylaws to provide stockholders holding 20% or more of the voting power of the Company’s outstanding capital stock (the “Required Percentage”) the right to call a special meeting. Under Section 2.02 of the Bylaws, special meetings shall be called by the Board or the Chairperson upon written request of the holders representing the Required Percentage of the Voting Stock.

The Board is committed to ensuring that stockholders are afforded meaningful and well-balanced opportunities for engaging, including through this special meeting right that has been available since 2016. The Board believes it is advisable and in the best interest of the Company to amend Article Twelfth to conform with the existing special meeting Bylaw provision by providing that special meetings shall be called by the Board or the Chairperson upon written request of the holders representing the Required Percentage of the Voting Stock who have delivered such request in accordance with and subject to the provisions of the Bylaws. The Special Meeting Amendment as proposed will eliminate any uncertainty under the Certificate of Incorporation regarding our stockholders ability to cause a special meeting to be called, provided the applicable Bylaw provisions are satisfied.

Process for Approval of Special Meeting Amendment

If stockholders approve the Special Meeting Amendment at the Annual Meeting, we intend to file with the Secretary of State of the State of Delaware a certificate of amendment to our Certificate of Incorporation that reflects the Special Meeting Amendment shown in Exhibit B, which will be effective upon filing. Stockholder approval of the Special Meeting Amendment shown in Exhibit B also will be deemed to constitute the approval of the filing of the certificate of amendment. The Board retains the discretion to abandon, and not implement, the Special Meeting Amendment at any time before it becomes effective, even if it is approved by our stockholders. The description of the Special Meeting Amendment is qualified in its entirety by, and should be read in conjunction with the full text of, the proposed Special Meeting Amendment, which is attached hereto and reflected in Exhibit B.

2025 Proxy Statement 79

RELATED PERSON TRANSACTIONS

Under our Code of Ethics and Business Conduct, our employees and directors must avoid any activity that conflicts with, or has the appearance of conflicting with, our business interests. At least annually, each director and executive officer completes a detailed questionnaire specifying any business relationship that may give rise to a conflict of interest with the Company.

Process for Review of Related Person Transactions. The Board has adopted a written policy for the review, approval and ratification of existing or proposed transactions to which the Company (or any subsidiary) is a party, when the aggregate amount involved in the transaction exceeds or is expected to exceed $100,000 and any director, director nominee, executive officer, greater-than-5% beneficial owner or their respective immediate family members (each, a “related person”) had, has or will have a direct or indirect material interest.

This policy requires the Governance and Policy Committee to review transactions subject to the policy and determine whether or not to recommend that the Board approve or ratify those transactions. In doing so, the Governance and Policy Committee may consider, among other factors:

•whether the transaction is on terms that are no less favorable to the Company than terms generally available to an unaffiliated third party under the same or similar circumstances;

•the extent of the related person’s interest in the transaction;

•the materiality of the proposed related person transaction;

•the actual or perceived conflict of interest between the Company and the related person;

•applicable law, including disclosure requirements;

•the Company’s Corporate Governance Guidelines and Code of Ethics and Business Conduct; and

•the best interests of the Company and our stockholders.

Although our policy generally requires that all related person transactions be reviewed and approved in advance, the Governance and Policy Committee has the authority to ratify a transaction (using the same standard of review) if a transaction is identified after it has occurred or commenced. The Governance and Policy Committee also has pre-approved certain categories of transactions or relationships, as set forth in the policy. If the Governance and Policy Committee does not recommend ratification of a related person transaction, or the Board does not ratify a related person transaction that is pending or ongoing, the Governance and Policy Committee will refer the transaction to management for amendment or termination and determine whether any other action is appropriate.

Transactions with Related Persons

Except as set forth below, there have been no related person transactions since the beginning of 2024 that required disclosure under the securities laws or that otherwise required review, approval or ratification by our Governance and Policy Committee under our Related Person Transactions Policy.

Who is Entitled to Vote at the Annual Meeting? Stockholders of record at the close of business on March 6, 2025, the record date, are eligible to vote at the meeting. As of the record date, there were [•] shares of our common stock outstanding. You may cast one vote for each share of common stock you hold as of the record date on all matters presented.

Why Did I Receive a “Notice of Internet Availability of Proxy Materials” But Not a Full Set of Proxy Materials? We distribute our proxy materials to stockholders via the internet under the “Notice and Access” approach permitted by the rules of the SEC. This process expedites receipt of proxy materials by stockholders, while also lowering our costs and reducing the environmental impact of our Annual Meeting. If you would like to receive a printed or electronic copy of this Proxy Statement and accompanying materials, you must follow the instructions for requesting such materials included in the Notice of Internet Availability of Proxy Materials.

How Do I Vote My Shares if I am a Record Holder? If you are a stockholder of record, you have four voting options. You may vote:

•By Internet. Registered stockholders may vote on the Internet, as well as view the documents, by logging on to www.envisionreports.com/HII and following the instructions given;

•By Telephone. Registered stockholders may vote by calling (800) 652-VOTE (8683) (toll-free) with a touch-tone telephone and following the recorded instructions;

GENERAL INFORMATION ABOUT THE ANNUAL MEETING

•By Mail. Registered stockholders may vote by signing and dating your proxy card (if you received a proxy card) and mailing it in the prepaid and addressed envelope. A paper copy of the proxy materials may be obtained by logging on to www.envisionreports.com/HII and following the instructions given; or

•Online at the Annual Meeting. Registered stockholders may vote while attending the Annual Meeting online via live webcast at https://meetnow.global/MVQTZRF.

Even if you plan to attend the Annual Meeting online, we encourage you to vote in advance by internet, telephone or mail so that your vote will be recorded in advance of the meeting. If you attend and vote at the Annual Meeting, any prior votes you submitted, whether by internet, telephone or mail, will be superseded by the vote you cast at the Annual Meeting.

How Do I Vote My Shares if my Shares are Held by a Bank, Broker or Other Nominee? If your shares are held in “street name” through a broker, bank or other nominee, you must complete and return the voting instruction form provided by your broker, bank, or nominee in order to instruct your broker, bank, or nominee on how to vote. Beneficial owners may view this Proxy Statement and the Annual Report on the internet by logging on to www.edocumentview.com/HII.

Beneficial owners who hold shares in “street name” may revoke a proxy or change a vote by submitting a new, later-dated voting instruction form, contacting the bank, broker, or other nominee or by voting at the Annual Meeting by obtaining a legal proxy as described above.

How Do I Vote My Shares Held Under an HII Savings Plan? If you hold shares through an HII savings plan, you cannot vote your shares directly. Instead, you can provide voting instructions to the plan Trustee, who will vote the shares on your behalf. If you are a plan participant and do not vote your shares, the Trustee will vote your shares in accordance with the terms of the relevant plan. As such, the Trustee may vote your shares in the same proportion as shares held by the plan for which voting instructions have been received from other participants, unless contrary to the Employee Retirement Income Security Act or other applicable law. Voting instructions from savings plan participants must be received by the applicable plan Trustee by 11:59 p.m. Eastern Daylight Time on April 27, 2025 in order to be used by the plan Trustee to determine the votes cast with respect to plan shares.

Can I Change my Vote? If you are a stockholder of record and you vote by proxy using any of the methods set forth above, you may revoke your proxy at any time and change your vote before the polls close, which may be done by delivering written notice of revocation to the Secretary, by delivering a valid, later-dated proxy or a later-dated vote by telephone or on the internet or by voting during the meeting. If your shares are held through a bank, broker, or other nominee, you must contact them to revoke a previously issued proxy.

Voting on Other Matters

We are not aware of any other business to be transacted at the Annual Meeting. If any other business properly comes before the Annual Meeting, the shares represented by proxies gives discretionary authority to the proxy holders to vote the shares in accordance with their judgment.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors, executive officers, and persons who own more than ten percent of our common stock to file reports of ownership and changes in ownership on Forms 3, 4, and 5 with the SEC.

Based solely upon a review of the Forms 3, 4, and 5 that are publicly available on the SEC’s EDGAR filing system and written representations from reporting persons, we believe that all required filings were made on a timely basis during the year ended December 31, 2024 other than (1) the Form 4s filed on July 12, 2024 on behalf of each of our executive officers, which included a delayed report of the acquisition of restricted stock rights on February 26, 2024 and dividends paid thereon on June 14, 2024 and (2) the Form 5 filed on January 2, 2025 on behalf of Mr. Kastner, which included a delayed report of the transfers of certain shares of common stock held directly by him to a family trust.

Householding Information

We have adopted a practice called “householding.” This means that stockholders of record sharing the same address may receive only one copy of the Notice of Internet Availability of Proxy Materials or the printed proxy materials, unless we have received contrary instructions from one or all of such stockholders. This practice is designed to reduce printing and mailing costs and is environmentally friendly.

•To Stop Receiving Separate Copies. If you currently receive multiple copies of the Notice of Internet Availability of Proxy Materials or the printed proxy materials, you can request to receive a single copy of the printed proxy materials in the future by calling our transfer agent, Computershare, at 1-888-665-9610, or writing to Computershare at www-us.computershare.com/Investor/ or HII at Investor Relations, 4101 Washington Avenue, Newport News, VA 23607.

•To Receive Separate Copies. If you wish to receive a separate Notice of Internet Availability of Proxy Materials or separate printed proxy materials, we will promptly deliver them to you if you request them by contacting Computershare by phone or Investor Relations in writing in the same manner described above.

If you are a street name stockholder, you can request householding by contacting your bank, broker, or other nominee through which you hold your shares.

Cost of Soliciting Proxies

We will pay the costs of soliciting proxies. In addition to solicitation by mail, telephone or other electronic means, our directors, officers, and employees may solicit proxies personally, by telephone, by email, or otherwise. These directors, officers, and employees will not receive additional compensation for the solicitation, but may, upon request, be reimbursed for out-of-pocket expenses incurred in connection with the solicitation. In addition, we have retained MacKenzie Partners, Inc. to assist in the solicitation of proxies for the 2025 Annual Meeting for a fee of $15,000, plus associated costs and expenses.

Copies of solicitation materials will be furnished to brokerage firms, fiduciaries, and other custodians that hold shares of our common stock of record for beneficial owners, for forwarding to such beneficial owners. We may also reimburse banks, brokers, and other holders of record for reasonable, out-of-pocket expenses for forwarding these proxy materials to you.

ANNEX A

Use of Non-GAAP Financial Measures

This Proxy Statement contains non-GAAP (accounting principles generally accepted in the United States of America) financial measures, as defined by SEC Regulation G and indicated by an asterisk in this Proxy Statement. While we believe these measures may be useful to investors and other users of our financial statements in evaluating our performance, they should be considered supplemental in nature and not in isolation or as a substitute for financial information presented in accordance with GAAP. Because not all companies use identical calculations, our presentation of these measures may not be comparable to similarly titled measures of other companies. Definitions and the reconciliations of the non-GAAP financial measures contained in this Proxy Statement, “segment operating income,” “segment operating margin,” and “free cash flow,” are provided below.

Segment Operating Income and Segment Operating Margin Rate. We internally manage our operations by reference to segment operating income and segment operating margin and use these measures to evaluate our core operating performance. We believe that segment operating income and segment operating margin reflect additional ways of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. These measures should be considered in addition to, and not as alternatives for, operating income and operating margin or any other performance measure presented in accordance with GAAP.

Segment operating income is defined as operating income for the relevant segment(s) before the Operating FAS/CAS Adjustment and non-current state income taxes.

Segment operating margin is defined as segment operating income as a percentage of sales and service revenues.

Free Cash Flow. We use free cash flow as a key operating metric in assessing the performance of our business and as a key performance measure in evaluating management performance and determining incentive compensation. We believe free cash flow is an important measure that may be useful to investors and other users of our financial statements because it provides insight into our current and period-to-period performance and our ability to generate cash from continuing operations. Free cash flow has limitations as an analytical tool and should not be considered in isolation from, or as a substitute for, net income as a measure of our performance or net cash provided by operating activities as a measure of our liquidity.

Free cash flow is defined as net cash provided by operating activities less capital expenditures net of related grant proceeds.

Certain of the financial measures we present are adjusted for the Operating FAS/CAS Adjustment and non-current state income taxes to reflect the Company’s performance based upon the pension costs and state tax expense charged to our contracts under U.S. Cost Accounting Standards (“CAS”). We use these adjusted measures as internal measures of operating performance and for performance-based compensation decisions.

Operating FAS/CAS Adjustment is defined as the difference between the service cost component of our pension and other postretirement expense determined in accordance with GAAP (“FAS”) and our pension and other postretirement expense under CAS.

Non-current state income taxes are defined as deferred state income taxes, which reflect the change in deferred state tax assets and liabilities and the tax expense or benefit associated with changes in state uncertain tax positions in the relevant period. These amounts are recorded within operating income. Current period state income tax expense is charged to contract costs and included in cost of sales and service revenues in segment operating income.

Exhibit A

Proposal 4: Elimination of Personal Liability of Officers for Monetary Damages for
Breach of Certain Fiduciary Duties as Permitted by Delaware Law

If Proposal 4 is adopted and effected, Article Fifteenth of the Restated Certificate of Incorporation of the Company would be amended as follows (with deletions shown as strike-through text and insertions shown as underlined text):

FIFTEENTH: A director or officer of the Corporation shall not be personally liable to the Corporation or to its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability (i) for any breach of the director’s or officer’s duty of loyalty to the Corporation or to its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) of a director under Section 174 of the General Corporation Law of the State of Delaware, or (iv) for any transaction from which the director or officer derives any improper personal benefit, or (v) of an officer in any action by or in the right of the Corporation. If, after approval of this Article by the stockholders of the Corporation, the General Corporation Law of the State of Delaware is amended to authorize the further elimination or limitation of the liability of directors or officers, then the liability of a director or officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware, as so amended. Solely for purposes of this Article, “officer” shall have the meaning determined in accordance with Section 102(b)(7) of the General Corporation Law of the State of Delaware, as so amended.

Any repeal or modification of this Article by the stockholders of the Corporation shall not adversely affect any right or protection of a director or officer of the Corporation existing at the time of such repeal or modification.

Exhibit B

Proposal 5: Amend Restated Certificate of Incorporation to Conform with Special
Meeting Bylaw

If Proposal 5 is adopted and effected, Article Twelfth of the Restated Certificate of Incorporation of the Company would be amended as follows (with insertions shown as underlined text):

TWELFTH: An annual meeting of the stockholders for the election of directors and for the transaction of such other business as may properly come before the meeting, shall be held at such place, on such date and at such time as the Board of Directors (or an authorized committee thereof) shall fix. Advance notice of stockholder nominations for the election of directors and of business to be brought by stockholders before any meeting of the stockholders of the Corporation shall be given in the manner provided in the Bylaws of the Corporation. The directors of the Corporation need not be elected by written ballot unless the bylaws so provide. Subject to the terms of any class or series of Preferred Stock and the next sentence, special meetings of the stockholders of the Corporation may be called only by the Board of Directors (or an authorized committee thereof) or the Chairperson of the Board of Directors. Special meetings of the stockholders of the Corporation may also be called at the request of stockholders of the Corporation in accordance with, and subject to the limitations set forth in, the Bylaws, as amended from time to time; provided that requests are received from the holders of at least 20% of the voting power of the outstanding capital stock of the Corporation. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting.
