Dear Fellow Stockholder:

On behalf of the Board of Directors, you are cordially invited to attend the 2015 Annual Meeting of Stockholders (the "Annual Meeting") of Spirit AeroSystems Holdings, Inc. (the "Company"). Details of the business to be conducted at the Annual Meeting are given in the attached Notice of Annual Meeting of Stockholders and accompanying Proxy Statement. We will meet on Wednesday, April 22, 2015 at the Mandarin Oriental, located at 3376 Peachtree Road NE, Atlanta, GA 30326, in the Azalea Room at 11:00 A.M. Eastern Time.

Last year was the first phase of a transformational journey for the Company. We began the year committing to focus on our strengths, manage costs efficiently, add to an already strong team from the best in our industry and position ourselves for growth.

I am very pleased to report that we are delivering on our commitments and are seeing significant measurable results. In 2014 we achieved:

•

Total stockholder return of 26 percent;

•

Improved performance and positive cash flow; and

•

Record total expected year-end backlog of approximately $46.6 billion.

We remain committed to, and are making strategic moves to position the company for, future growth and delivering value to our stockholders.

The strategy we outlined when I joined the company in 2013 still applies today: stability and growth. Our hard work has stabilized the business in 2014 and will provide the necessary foundation upon which to build in 2015 and beyond. Our focus in 2015 will be on quality, affordability and reliability in order to continue progress through our transformation.

Your vote is important. Whether or not you plan to attend the Annual Meeting in person, I urge you to complete, sign and date the enclosed proxy card and return it promptly in the enclosed envelope. If you decide to attend the Annual Meeting, you will be able to vote in person, even if you have previously submitted your proxy card. Thank you for your continued support of Spirit AeroSystems Holdings, Inc. I look forward to greeting as many of our stockholders as possible at the Annual Meeting.

Sincerely,

Larry A. Lawson
President and Chief Executive Officer

We realize that many cellular phones and other wireless mobile devices have built-in digital cameras, and while these devices may be brought into the venue, the camera function may not be used at any time.

Proxy Statement for the 2015
Annual Meeting of Stockholders

General Information Regarding the Annual Meeting

This Proxy Statement, which was first mailed to stockholders on or about March 19, 2015 (the "Mailing Date"), is furnished in connection with the solicitation of proxies by the Board of Directors (the "Board") of SPIRIT AEROSYSTEMS HOLDINGS, INC. (the "Company"), to be voted at the Company's 2015 Annual Meeting of Stockholders (the "Annual Meeting"), which will be held at 11:00 A.M. Eastern Time on Wednesday, April 22, 2015 in the Azalea Room at the Mandarin Oriental, located at 3376 Peachtree Road NE, Atlanta, GA 30326, for the purposes set forth in the accompanying Notice of 2015 Annual Meeting of Stockholders.

Any stockholder signing and returning the enclosed proxy has the power to revoke it by (1) giving written notice of revocation of such proxy to the Company's Corporate Secretary at the address set forth above, (2) completing, signing and submitting a new proxy card relating to the same shares and bearing a later date, or (3) attending the Annual Meeting and voting in person, although attendance at the meeting will not, by itself, revoke a proxy. The shares represented by the enclosed proxy will be voted as specified therein if said proxy is properly signed and received by the Company prior to the time of the Annual Meeting and is not properly revoked. The expense of this proxy solicitation will be borne by the Company. The Company's principal executive offices are located at 3801 South Oliver, Wichita, KS 67210.

The Board has fixed the close of business on March 2, 2015 as the record date (the "Record Date") for determining the holders of Common stock entitled to notice of and to vote at the Annual Meeting. On the Record Date, there were 138,887,074 shares of Class A Common stock outstanding, held of record by approximately 853 stockholders. Each outstanding share of Class A Common stock is entitled to one vote. On the Record Date, there were 121 shares of Class B Common stock outstanding, held of record by one stockholder. Each outstanding share of Class B Common stock is entitled to one vote. Each outstanding share of Class B Common stock is convertible into one share of Class A Common stock at the option of the holder.

Vote Required for Approval

The presence, in person or by proxy, of stockholders entitled to cast a majority of the votes which all stockholders are entitled to cast at the Annual Meeting is necessary to constitute a quorum for the transaction of business. The Company will count abstentions and "broker non-votes" only for the purpose of determining the presence or absence of a quorum. "Broker non-votes" occur when a person holding shares through a bank or brokerage account does not provide instructions as to how his or her shares should be voted and the broker does not exercise discretion to vote those shares on a particular matter.

Under the rules of the New York Stock Exchange ("NYSE"), brokers may exercise discretion to vote shares as to which instructions are not given only with respect to certain "routine" matters. Under the NYSE rules, Proposal 2 (ratification of the selection of our independent registered public accounting firm) and Proposal 3 (approval of Fourth Amended and Restated Bylaws of the Company to delete certain obsolete provisions and make minor changes to certain provisions of the Company's existing bylaws) are considered to be routine matters. As a result, a stockholder's broker is permitted to vote the stockholder's shares on Proposal 2 and Proposal 3 at its discretion without instructions from the stockholder.

Proposal 1 (election of the nine members of the Board) is not considered to be a routine matter. Accordingly, brokerage firms are not permitted to vote shares for which they have not received voting instructions on this proposal.

With respect to Proposal 1 (election of the nine members of the Board), a plurality of the votes cast in person or by proxy at the Annual Meeting and entitled to vote on the matter, is necessary for election of each member. As a result, the nine nominees receiving the greatest number of votes will be elected. With respect to Proposal 1, a stockholder may vote

Table of Contents

"FOR" all nominees, "WITHHOLD" its vote as to all nominees, or vote "FOR" all nominees except those specific nominees from whom the stockholder "WITHHOLDS" its vote. A properly executed proxy marked "WITHHOLD" with respect to the election of one or more directors will not be voted with respect to the director or directors indicated. The Company's stockholders do not have cumulative voting rights. Any shares not voted (whether by abstention, "broker non-vote" or otherwise) will have no impact on the election of the members of the Board.

Proposal 2 (ratification of the selection of the Company's independent registered public accounting firm) and Proposal 3 (approval of the proposed Fourth Amended and Restated Bylaws of the Company) will be approved if stockholders entitled to cast a majority of the votes which all stockholders present, in person or by proxy, are entitled to vote on the matter, vote "FOR" the proposal. With respect to Proposals 2 and 3, a stockholder may vote "FOR", "AGAINST" or "ABSTAIN". Abstentions and "broker non-votes" will not be counted as votes "FOR" or "AGAINST" Proposal 2. However, because abstentions and "broker non-votes" will be counted as present at the Annual Meeting, they will have the effect of votes "AGAINST" Proposals 2 and 3.

Votes submitted by mail will be voted by the individuals named on the card (or the individuals properly authorized) in the manner indicated. If a stockholder submits a duly executed proxy and does not specify how shares should be voted, they will be voted in accordance with the Board's recommendations. Stockholders who hold shares in more than one account must vote each proxy and/or voting instruction card received to ensure that all shares owned are voted.

Votes cast by proxy or in person at the Annual Meeting will be received and tabulated by Computershare Shareowners Services, the Company's transfer agent and the inspector of elections for the Annual Meeting.

Householding of Annual Meeting Materials

Some brokers and other nominee record holders may be participating in the practice of "householding" proxy statements. This means that only one copy of the Proxy Statement may have been sent to multiple stockholders in a stockholder's household. The Company will promptly deliver a separate copy of the Proxy Statement to any stockholder who contacts the Company's Investor Relations Department by writing to Spirit AeroSystems, Investor Relations, P.O. Box 780008, Wichita, KS 67278-0008, or by calling (316) 523-7040 or by sending an email request to investorrelations@spiritaero.com. If a stockholder is receiving multiple copies of the Proxy Statement at the stockholder's household and would like to receive a single copy of the Proxy Statement for a stockholder's household in the future, the stockholder should contact his or her broker, other nominee record holder, or the Company's Investor Relations Department to request mailing of a single copy of the Proxy Statement.

Corporate Governance and the Board of Directors

Corporate Governance Information

The Company's Corporate Governance Guidelines and the charters of the four standing committees of the Board describe the governance practices followed by the Company. The Corporate Governance Guidelines and committee charters are intended to ensure that the Board has the necessary authority and practices in place to review and evaluate the Company's business operations; to make decisions that are independent of the Company's management; and to monitor adherence to the Company's standards and policies. The Corporate Governance Guidelines are also intended to align the interests of the Company's directors and management with those of the Company's stockholders. The Corporate Governance Guidelines establish the practices the Board follows with respect to the obligations of the Board and each director; Board composition and selection; Board meetings and involvement of senior management; chief executive officer performance evaluation and elected officer succession planning; Board committee composition, responsibilities and meetings; director compensation; director orientation and education; stockholders' advisory vote for say-on-pay; and director access to members of management, employees and independent advisors. The Board annually conducts a self-evaluation to identify opportunities to improve Board performance.

The Corporate Governance Guidelines and committee charters are reviewed periodically and updated as necessary to reflect changes in regulatory requirements and evolving oversight practices. The Corporate Governance Guidelines comply with corporate governance requirements contained in the listing standards of the NYSE and make enhancements to the Company's corporate governance policies.

In 2014, the Corporate Governance and Nominating Committee reviewed the Corporate Governance Guidelines and considered various corporate governance principles that merit consideration by the Board. As a result of its review, the Corporate Governance and Nominating Committee recommended certain improvements to the Corporate Governance Guidelines and amended the Corporate Governance Guidelines in July 2014.

Current copies of the Corporate Governance Guidelines and Code of Ethics and Business Conduct are available under the "Investor Relations" portion of the Company's website, www.spiritaero.com.

Director Independence

In June 2014, Onex Corporation (together with its affiliates, "Onex"), ceased to control a majority of the Company's voting common stock. As a result, the Company no longer qualifies as a "controlled company" within the meaning of the NYSE corporate governance standards. The NYSE rules require that the Company appoint a majority of independent directors to the Board of Directors within one year of the date the Company no longer qualifies as a "controlled company." The NYSE rules also require that each of the Compensation Committee and Corporate Governance and Nominating Committee be composed solely of "independent directors," as defined under the rules of the NYSE, within one year of the date the Company no longer qualifies as a "controlled company." During these transition periods, the Company may elect not to comply with certain NYSE corporate governance requirements, including:

•

the requirement that the Company has a nominating and corporate governance committee that is composed entirely of independent directors; and

•

the requirement that the Company has a compensation committee that is composed entirely of independent directors.

The Company continues to be subject to the independence requirements for the Company's Audit Committee. Accordingly, the Company complies with the requirements of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act") and the NYSE rules, which require that the Company's Audit Committee be comprised of independent directors exclusively.

The Board annually examines and makes a determination of each director's and each nominee's independence based on criteria set forth in the NYSE rules. The Board considers all relevant circumstances when examining director independence. For directors employed by, or serving as directors of, companies with which the Company does business in the ordinary course, the Board examined the amount paid by the Company to those companies and by those companies to the Company. The Board also examined the directors' memberships on other public company boards and private company, civic and not-for-profit boards, as well as any executive positions that the directors may hold and any consulting and other services that they may provide.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

Based on this analysis, the Board has determined that the following directors and nominees meet the standards of independence under the Company's Corporate Governance Guidelines and applicable NYSE listing standards, including that each such director and nominee is free of any relationship that would interfere with his individual exercise of independent judgment: Mr. Chadwell, Mr. Evans, Mr. Fulchino, Mr. Gephardt, Mr. Johnson, Mr. Kadish, Mr. Kubasik, Mr. Plueger and Mr. Raborn. Although the Company qualifies for an exception to certain board of directors and committee composition requirements under the NYSE rules for a period of one year following the date the Company ceased to qualify as a "controlled company", independent directors currently comprise a majority of the Board, and will continue to comprise a majority following the Annual Meeting if all of the nominees for directors are elected. Following the Annual Meeting, if all of the nominees for directors are elected, the Company's Audit Committee, Compensation Committee, Corporate Governance and Nominating Committee and Risk Committee will each be comprised solely of independent directors.

Certain Relationships and Related Person Transactions

Related-person transactions have the potential to create actual or perceived conflicts of interest between the Company and its directors and executive officers or their immediate family members. The Board, as advised by the Corporate Governance and Nominating Committee, reviews such matters as they pertain to transactions with related persons as described by Item 404(a) of the SEC's Regulation S-K. In deciding whether to continue to allow these related-person transactions involving a director, executive officer or their immediate family members, the Board considered, among other factors:

•

information about the goods or services proposed to be or being provided by or to the related party or the nature of the transactions;

•

the nature of the transactions and the costs to be incurred by the Company or payments to the Company;

•

an analysis of the costs and benefits associated with the transaction and a comparison of comparable or alternative goods or services that are available to the Company from unrelated persons;

•

the business advantage the Company would gain by engaging in the transaction; and

•

an analysis of the significance of the transaction to the Company and to the related person.

The Board determined that the related person transactions disclosed herein are on terms that are fair and reasonable to the Company, and which are as favorable to the Company as would be available from non-related entities in comparable transactions. The Board believes that there is a Company business interest supporting the transactions disclosed herein and that the transactions meet the same Company standards that apply to comparable transactions with unaffiliated entities.

The Board has adopted a written Related Person Transaction Policy that is communicated to the appropriate level of management and can be found under the "Investor Relations" portion of the Company's website, www.spiritaero.com. Under the policy, a related person transaction is (1) any financial transaction (including any indebtedness or guarantee of indebtedness) in which the Company or any of its subsidiaries was, is, or will be a participant, where the amount involved exceeds $120,000 within a 24-month period, and in which a Related Person (as defined in the policy) had, has or will have a direct or indirect "material interest" as determined by the Corporate Governance and Nominating Committee, or (2) any business, consulting, professional or similar relationship which a Related Person had, has or will have, directly or indirectly, with any material customer or supplier of the Company, where the amount of compensation involved exceeds $120,000 within a 24-month period.

The Corporate Governance and Nominating Committee is responsible for reviewing these transactions and may take into consideration, among other things, (1) the materiality of the transaction; (2) the actual or perceived conflict of interest between the Company and the related person; (3) the impact on the transaction of applicable corporation and fiduciary duty laws and rules; (4) whether any products or services provided by the related person are provided on an arm's-length basis on terms comparable to those provided by unrelated third persons; (5) whether any products or services provided by the related person are of a nature, quantity or quality, or on other terms, that are not readily available from alternative sources; (6) disclosure considerations; (7) the potential impact of the transaction on the Company's relations with its customers, suppliers, stockholders and securities markets; (8) the Company's Corporate Governance Guidelines and Code of Ethics and Business Conduct; (9) the potential impact of the transaction on the objectivity of the related person; and (10) the best interests of the Company and its stockholders.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

After review of the relevant facts and circumstances, if the Corporate Governance and Nominating Committee concludes that the related person transaction is in, or is not opposed to, the best interests of the Company and its stockholders, it may approve or ratify the transaction. If the Corporate Governance and Nominating Committee declines to approve or ratify any related person transaction, the Company's general counsel, in coordination with the affected business unit or corporate function, will review the transaction, determine whether it should be terminated or amended in a manner that is acceptable to the Corporate Governance and Nominating Committee, and advise the Corporate Governance and Nominating Committee of his or her recommendation. The Corporate Governance and Nominating Committee will then consider the recommendation at its next meeting. If the general counsel does not ultimately recommend the transaction to the Corporate Governance and Nominating Committee, or if the Corporate Governance and Nominating Committee does not approve the transaction, the proposed transaction will not be pursued or, if the transaction has already been entered into, the Corporate Governance and Nominating Committee will determine an appropriate course of action with respect to the transaction.

Below are the transactions that occurred or have continued since the beginning of the fiscal year 2014, or any currently proposed transactions, in which, to the Company's knowledge, the Company was or is a party and the amount involved exceeded $120,000, and in which any director, director nominee, executive officer, holder of more than 5% of any class of the Company's Common stock, or any member of the immediate family of any of the foregoing persons had or will have a direct or indirect material interest.

In December 2014, Onex acquired approximately a 40% interest in Advanced Integration Technologies ("AIT"), a provider of automation and tooling, maintenance services and aircraft components to the aerospace industry and a supplier to the Company. For the twelve months ended December 31, 2014, sales from AIT to the Company and its subsidiaries collectively totaled approximately $11 million. Mr. Popatia is a Managing Director of Onex and is a director of the Company.

In addition, the Company paid approximately $300,000, including reimbursement of expenses, to Onex during the fiscal year 2014 for various consulting services rendered by it to the Company.

Nomination of Directors

The Corporate Governance and Nominating Committee is responsible for identifying and evaluating qualified potential candidates to serve on the Board and recommending to the Board for its selection those nominees to stand for election as directors at the Company's Annual Meeting of Stockholders. While the Corporate Governance and Nominating Committee has established no minimum eligibility requirements for candidates to serve on the Board, in performing its duties, the Corporate Governance and Nominating Committee considers any criteria approved by the Board or that the Corporate Governance and Nominating Committee deems appropriate, including but not limited to the candidate's judgment, skill, education, diversity, age, relationships and experience with businesses and other organizations; whether the candidate meets the independence requirements of applicable legal and listing standards; the organization, structure, size and composition of the Board and the interplay of the candidate's experience with the experience of other Board members; the qualifications and areas of expertise needed to further enhance the deliberations of the Board; whether the candidate maintains a security clearance with the Department of Defense ("DoD"); and the extent to which the candidate would be a desirable addition to the Board and any committees of the Board.

Each potential candidate to serve on the Board must satisfy the requirements of the Company's certificate of incorporation and bylaws, conform to high standards of integrity and ethics, and have a commitment to act in the best interest of the Company and its stockholders.

The Corporate Governance and Nominating Committee will consider stockholder recommendations for candidates to the Board on the same basis that it considers all other candidates recommended to it. To recommend a director candidate to the Corporate Governance and Nominating Committee, a stockholder must provide the Company with a written notice that contains, to the extent known to the nominating stockholder, (1) the name, age, business address and residence address of the nominating stockholder and the person to be nominated; (2) the total number and class of all shares of capital stock and other securities of the Company that are owned beneficially and of record by the person to be nominated and by the nominating stockholder and, if such securities are not owned solely and directly by the nominating stockholder or the proposed nominee, the manner of beneficial ownership (beneficial ownership has the same meaning as provided in Regulation 13D under the Securities Exchange Act of 1934, as amended (the "Exchange Act")); (3) the principal occupation of the proposed nominee; (4) a representation that the nominating stockholder is a holder of record of stock of the Company entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to

nominate the person or persons specified in the notice; (5) a description of all arrangements or understandings between the nominating stockholder or any of its affiliates or associates, and any others acting in concert with any of the foregoing, each person to be nominated, and any other person or persons (naming such person or persons) pursuant to which the nomination is to be made by the nominating stockholder; (6) such other information regarding such nominating stockholder and each person to be nominated by such stockholder as would be required to be included in a proxy statement filed pursuant to the proxy rules of the SEC, had the nominee been nominated, or been intended to be nominated, by the Board; and (7) the consent of the person to be nominated to serve as a director of the Company, if so elected, to be named in the Company's proxy statement (whether or not nominated), and the consent of the nominating stockholder to be named in the Company's proxy statement (whether or not the Board chooses to nominate the recommended nominee). The Company may request any proposed nominee to furnish such other information as may reasonably be required by the Company to determine the qualifications of the proposed nominee to serve as a director of the Company. If a stockholder wishes to formally nominate a candidate, he or she must follow the procedures described in the Company's bylaws.

All director candidate recommendations and formal nominations for membership to the Board for the 2016 Annual Meeting of Stockholders must be sent to the Company at the address set forth below and received by the date specified for stockholder proposals. See "Other Matters — Stockholders Proposals to Be Presented at the 2016 Annual Meeting of Stockholders" below. The Company's presiding officer at the Annual Meeting of Stockholders may refuse to acknowledge the nomination of any person not made in compliance with the foregoing procedure.

Experience, Qualifications, Attributes and Skills of the Members of the Board of Directors

The Board believes that the Board, as a whole, should possess a combination of skills, professional experience and diversity of backgrounds necessary to oversee the Company's business. In addition, the Board believes that there are certain attributes that every director should possess, as reflected in the Board's membership criteria. Accordingly, the Board and the Corporate Governance and Nominating Committee consider the qualifications of directors and director candidates individually and in the broader context of the Board's overall composition and the Company's current and future needs.

The Corporate Governance and Nominating Committee is responsible for developing and recommending criteria for director nominees to the Board for approval. As discussed above, while the Corporate Governance and Nominating Committee has established no minimum eligibility requirements for candidates to serve on the Board, in performing its duties, the Corporate Governance and Nominating Committee considers any criteria approved by the Board or that the Corporate Governance and Nominating Committee deems to be appropriate. All of the Company's Board members share certain qualifications and attributes consistent with the general criteria set forth in the Company's Corporate Governance Guidelines. For example, each of them possesses specific skills and experience aligned with the Company's strategic direction and operating challenges and that complement the overall composition of the Board. In addition, each Board member has demonstrated certain core business competencies, including high achievement and a record of success, financial literacy, a history of making good business decisions and exposure to best practices. All of the Company's Board members also possess interpersonal skills that maximize group dynamics, including respect for others, strong communication skills and confidence to ask thought-provoking questions. The Board members are enthusiastic about the Company and devote sufficient time to be fully engaged in their roles as Board members. Finally, upon the expiration of Mr. Popatia's current term as a director, all of the Company's non-employee directors will satisfy the independence requirements of the NYSE and the SEC rules.

In addition, the Corporate Governance and Nominating Committee annually reviews the Board's requirements for Board members and the appropriate criteria for membership to the Board.

The Board also recognizes that the Company is more effectively governed when a diversity of viewpoints, backgrounds, opinions, skills, expertise, experiences and industry knowledge are represented on the Board. Accordingly, in October 2011, the Corporate Governance and Nominating Committee adopted the Board of Directors Diversity Policy for considering diversity in identifying nominees for director. The Board of Directors Diversity Policy provides that, in nominating candidates for election to the Board at each Annual Meeting of Stockholders, the Corporate Governance and Nominating Committee and the Board shall select individuals who represent a diversity of viewpoint, professional experience, education, skill, expertise, industry knowledge and such other factors as the Corporate Governance and Nominating Committee and the Board believe would enhance the diversity of the Board and the effective governance of the Company. Accordingly, diversity of thought, experience, gender, race and ethnic background are considered in the director evaluation process.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

As discussed under the heading "Proposal 1: Election of Directors — Information Regarding Nominees for Election as Directors", the Company's directors have experience with businesses that operate in industries in which the Company and its subsidiaries operate, including commercial aviation, aviation supply and maintenance, and defense industries, or that involve important skills necessary to advise the Company in strategic areas, including finance, general management, labor negotiations, governmental affairs and business strategy. The Corporate Governance and Nominating Committee has taken the specific experience, qualifications, attributes and skills of the individual Board members into account in concluding that each nominee should continue to serve on the Board.

Stockholders and other interested persons may send communications to the Board, the chairman of the Board, individual members of the Board, members of any committee of the Board, or one or more non-management directors by letter addressed to Investor Relations at Spirit AeroSystems Holdings, Inc., 3801 South Oliver, Wichita, KS 67210, or by contacting Investor Relations at (316) 523-7040. These communications will be received and reviewed by the Company's Investor Relations office. The receipt of concerns about the Company's accounting, internal controls, auditing matters or business practices will be reported to the Company's Audit Committee. The receipt of other concerns will be reported to the appropriate committee(s) of the Board. The Company's employees also can raise questions or concerns confidentially or anonymously using the Company's Ethics Hotline. This hotline provides the Company's employees, suppliers and other stakeholders with a mechanism for reporting unethical activities and/or financial irregularities to the Board anonymously. Such persons are able to file reports via a web-based process or a toll free telephone number. Data reported to the Ethics Hotline is reviewed quarterly with the Audit Committee and with the Company's independent registered public accounting firm to help ensure that the Company's ethics and compliance programs remain effective. The Ethics Hotline is operated by a third-party service provider and is available 24 hours a day, 7 days a week and 365 days a year. Receipt of communications clearly not appropriate for consideration by members of the Board, such as unsolicited advertisements, inquiries concerning the products and services of the Company and harassing communications, are not forwarded to members of the Board.

Board Leadership Structure

The Company separates the roles of chief executive officer of the Company and chairman of the Board in recognition of the differences between the two roles. The chief executive officer is responsible for setting the strategic direction for the Company and the day to day leadership and performance of the Company, while the chairman of the Board provides guidance to the chief executive officer, sets the agenda for Board meetings and presides over meetings of the full Board. Because Mr. Johnson, the chairman of the Board, is not an employee of the Company and has been determined to be an "independent director", as defined under the rules of the NYSE, the Board has not deemed it necessary to appoint a lead independent director. The chairman of the Board also presides at all executive sessions of non-management directors and serves as the focal point for directors regarding resolving conflicts with the chief executive officer or other directors and coordinating feedback to the chief executive officer on behalf of directors regarding business issues and Board management. The Board generally holds executive sessions four times a year without the chief executive officer or other employees present, unless the presence of the chief executive officer and/or any other employees is requested by the Board.

The Board of Directors' Role in Risk Oversight

The Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to achieve planned long-term organizational performance and enhance stockholder value. A fundamental part of risk management is not only understanding the risks of a company and what steps are required to manage those risks, but also understanding what level of risk is appropriate for that company. The involvement of the full Board in setting the Company's business strategy is a key part of its assessment of management's appetite for risk and also a determination of what constitutes an appropriate level of risk for the Company.

The Board's role in the Company's risk oversight process includes receiving regular reports from members of the Company's senior management on areas of material risk to the Company. The Board (or the appropriate committee in the case of risks that are under the purview of a particular committee) receives these reports from the appropriate "risk owner" within the organization to enable it to understand the Company's risk identification, risk management and risk mitigation strategies.

CORPORATE GOVERNANCE AND THE BOARD OF DIRECTORS

While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. In particular, the Board has delegated to the Risk Committee and the Audit Committee primary oversight of the risk management process. The Risk Committee provides oversight of management's guidelines, policies and processes for assessing, monitoring and mitigating the Company's critical enterprise risks, including the major strategic, operational, financial and compliance risks inherent in the Company's business and core strategies, determines which risks need to be included on the board's agenda for discussion and assists the Board in its oversight of the Company's management of key risks that have the potential to significantly affect the Company's ability to execute its strategy and achieve its strategic business objectives and performance goals.

The Audit Committee, in collaboration with the Risk Committee, focuses on a broad range of legal, financial and operational risks, including internal controls, disclosure issues, contract accounting, Sarbanes-Oxley Act compliance, Ethics Hotline reports and legal and regulatory issues, including compliance with SEC rules and regulations. The Audit Committee annually reviews a comprehensive annual risk assessment report from the Company's internal auditors. The internal audit report surveys risks throughout the business, focusing on primary areas of risk, including operational, financial, contractual, legal and regulatory, strategic and reputational risks. The Audit Committee, in collaboration with the Risk Committee, looks at the relative magnitude of these risks and management's mitigation plan, and provides strategic advice to the Company about ways to reduce and contain risk.

In addition, in setting compensation, the Compensation Committee strives to create incentives that encourage a level of risk-taking behavior consistent with the Company's business strategy. Such incentives are also designed to align the Company's executives' interests with those of the Company's stockholders by tying executive compensation to stockholder return and value.

Finally, the Board's Corporate Governance and Nominating Committee, in collaboration with the Risk Committee, assists with risk mitigation by ensuring that the Board and its committees are composed of individuals with the appropriate credentials and backgrounds to assist the Company with its risk mitigation efforts, while ensuring that the Company complies with all applicable NYSE, SEC and other public company governance requirements.

Committees of the Board

The Board has four standing committees: the Audit Committee, the Compensation Committee, the Corporate Governance and Nominating Committee and the Risk Committee. On October 27, 2014, the Board terminated its Government Security Committee following the termination of the Special Security Agreement among Onex, the Company and the Department of Defense. At the April 30, 2014 Board meeting, Messrs. Chadwell, Evans, Kubasik and Raborn were reappointed to the Audit Committee, Messrs. Fulchino, Gephardt, Johnson and Popatia were reappointed to the Compensation Committee and Messrs. Fulchino, Gephardt, Kadish and Popatia were reappointed to the Corporate Governance and Nominating Committee. At the July 29, 2014 Board meeting, Mr. Plueger was appointed to the Audit Committee, Messrs. Evans, Kadish, Kubasik, Plueger and Raborn were appointed to the Risk Committee, Mr. Chadwell was appointed to the Compensation Committee, and Messrs. Chadwell and Johnson were appointed to the Corporate Governance and Nominating Committee. At the January 29, 2015 Board meeting, it was decided that Mr. Chadwell would cease to serve on the Audit Committee due to scheduling conflicts with other Board committee meetings. Five formal meetings of the Audit Committee, six formal meetings of the Compensation Committee, six formal meetings of the Corporate Governance and Nominating Committee, three formal meetings of the Government Security Committee and one formal meeting of the Risk Committee (which was first established on July 29, 2014) were held in 2014.

Below is a description of the duties and composition of each standing committee of the Board. Each committee has authority to engage legal counsel or other advisors or consultants as it deems appropriate to carry out its responsibilities. Directors hold committee memberships for a term of one year until the next Annual Meeting of Stockholders or, if later, until their successors are elected and qualified, or until their death, retirement, resignation or removal.

Audit Committee.    In accordance with the Company's Audit Committee Charter, the Audit Committee is responsible for, among other things, (1) selecting and overseeing the independent registered public accounting firm; (2) pre-approving the overall scope of the audit and quarterly financial review; (3) reviewing the independent registered public accounting firm's report describing the auditing firm's internal quality-control procedures and any material issues raised by the most recent internal quality-control review or peer review of the auditing firm; (4) in collaboration with the Risk Committee, reviewing and discussing with management, the independent registered public accounting firm and the internal auditor, the Company's risk assessment and risk management practices, guidelines, policies and processes; (5) in

The Company's Audit Committee consists of Messrs. Evans, Kubasik, Plueger and Raborn, with Mr. Raborn serving as chairman. All of the Audit Committee members have been determined to be independent within the meaning of the NYSE listing standards, and Mr. Raborn has been determined to be an "audit committee financial expert," as such term is defined in Item 407(d)(5) of SEC Regulation S-K. Following the conclusion of Mr. Evans' current term as a director and the Annual Meeting, if all of the nominees for director are elected, the Audit Committee's members will consist of Messrs. Kubasik, Plueger and Raborn. The Audit Committee has a written Audit Committee Charter, the current copy of which can be found under the "Investor Relations" portion of the Company's website, www.spiritaero.com.

Compensation Committee.    In accordance with the Company's Compensation Committee Charter, the Compensation Committee is responsible for, among other things, (1) developing and modifying, as appropriate, a competitive compensation philosophy and strategy for the Company's directors and executive officers that promotes the recruitment and retention of talented individuals; (2) reviewing and approving goals and objectives with respect to compensation for the Company's chief executive officer; (3) reviewing and approving the evaluation process and compensation structure for the Company's officers; (4) establishing and reviewing policies concerning perquisite benefits, including adopting a perquisite allowance policy for senior executives and other officers; (5) reviewing the Company's equity and other stock-based incentive plans, and recommending any changes to those plans; (6) reviewing the Company's incentive compensation arrangements to confirm that incentive pay does not expose the Company to unnecessary or excessive risk, and reviewing the relationship among the Company's risk management policies and practices, corporate strategy and senior executive compensation; (7) reviewing the results of periodic say-on-pay advisory votes by the Company's stockholders and determining the weight to be given to those results in making compensation decisions; (8) reviewing and discussing with management the Compensation Discussion and Analysis section in the Company's annual proxy statement; (9) determining whether employment contracts and severance arrangements should be established with senior executive officers and approving the terms of those agreements and arrangements; (10) discussing the relationship between the Company's executive compensation and financial and share performance; (11) discussing the ratio between the total annual compensation for the Company' s chief executive officer and the median annual compensation of the Company's other employees; (12) adopting a policy, or providing in executive employment agreements, for the clawback of unearned incentive compensation if the Company is required to restate its financials due to material noncompliance with financial reporting requirements; (13) preparing the Compensation Committee's report for inclusion in the Company's proxy statement; (14) reviewing director compensation; (15) conducting a self-evaluation of the performance of the Compensation Committee and reassessing its charter; and (16) reporting to the full Board.

of the nominees for director are elected, the Risk Committee's members will consist of Messrs. Kadish, Plueger, Kubasik and Raborn. The Risk Committee has a written charter, the current copy of which is available under the "Investor Relations" portion of the Company's website, www.spiritaero.com.

Other Committees.    The Board may establish other committees as it deems necessary or appropriate from time to time, including special committees.

Board Meetings and Attendance; Attendance at Annual Meeting of Stockholders

During the fiscal year 2014, there were sixteen formal meetings of the Board and additional actions by unanimous written consent. All of the then-current directors attended at least 75% of the aggregate of (i) the total number of meetings (whether regular or special meetings) of the Board (held during the period for which such person was a director), and (ii) the total number of meetings held by all committees of the Board on which the director served (during the period that such director served), and a majority of the then-current directors attended 100% of such meetings. Recognizing that director attendance at the Annual Meeting of Stockholders can provide the Company's stockholders with an opportunity to communicate with Board members about issues affecting the Company, the Company actively encourages the members of the Board to attend its Annual Meeting of Stockholders. The Company held its 2014 Annual Meeting of Stockholders on April 30, 2014, and it was attended by all then-current members of the Board.

Executive Sessions of Non-Management Directors

The non-management directors meet in executive session at least four times a year and generally at every regularly scheduled Board meeting to consider such matters as they deem appropriate, without the Company's chief executive officer or other management present unless the presence of the Company's chief executive officer or other management is requested by the Board. In accordance with NYSE listed company rules, "non-management" directors are all those who are not executive officers of the Company. Among the items that the non-management directors meet privately in executive sessions to review is the performance of the Company's chief executive officer and recommendations of the Compensation Committee concerning compensation for employee directors and other senior executive officers. Mr. Johnson, who serves as the chairman of the Board, acts as the chair of the executive sessions of the non-management directors.

Compensation Committee Interlocks and Insider Participation

None of the Company's executive officers served during fiscal year 2014 or currently serves, and the Company anticipates that none will serve, as a member of the board of directors or compensation committee of any entity (other than the Company) that has one or more executive officers that serves on the Company's Board or Compensation Committee. Mr. Popatia serves on the Company's Compensation Committee and has a relationship that qualified as a related person transaction. See "Certain Relationships and Related Person Transactions" concerning this relationship. Mr. Popatia has informed the Board that he has decided not to run for reelection at the Annual Meeting, and following the conclusion of Mr. Popatia's current term as a director he will cease to be a member of the Company's Compensation Committee.

Miscellaneous

There are no family relationships among executive officers and directors of the Company.

Compensation of Non-Management Directors

Non-management directors' compensation is set by the Board at the recommendation of the Compensation Committee. In developing its recommendations, the Compensation Committee is guided by the following goals: compensation should fairly pay directors for work required in companies similar in size and scope to the Company; compensation should align directors' interests with the long-term interests of the Company's stockholders; and the structure of the compensation should be simple, transparent and easy for stockholders to understand.

The Compensation Committee reviews and recommends to the Board for its approval all compensation of the Company's non-employee directors, but no member of the Compensation Committee may act to fix his or her own compensation except as uniformly applied to all of the Company's non-employee directors for their service on the Board.

In 2005, the Board adopted a Director Stock Plan to provide certain non-employee directors of the Company or its subsidiary Spirit AeroSystems, Inc. ("Spirit") with the opportunity to acquire equity in the Company through grants of restricted shares of the Company's Class B Common stock. On April 21, 2008, the Board amended the Director Stock Plan to allow for grants of restricted stock units, provide for the grants of restricted shares of the Company's Class A Common stock or restricted stock units to comprise one-half of each non-employee director's annual director fee and provide for a one-year service vesting condition. Upon ceasing to serve as a director, a recipient will forfeit any restricted stock which was granted to him within the one-year period prior to his ceasing to serve as a director and in which he has not before then acquired an interest, unless the one-year service requirement is waived by the Board. Following the approval of the 2014 Omnibus Incentive Plan (the "OIP") at the Company's 2014 Annual Meeting of Stockholders, the Board established a Director Stock Program under the OIP, pursuant to which grants to directors are made beginning in 2014. Under the Director Stock Plan, from inception through December 31, 2013, the Company's and Spirit's non-employee directors received grants of an aggregate of 390,000 shares of Class B restricted Common stock, 10,129 restricted stock units and 198,726 shares of Class A restricted Common stock. Under the Director Stock Program, from January 1, 2014 through December 31, 2014, the Company's and Spirit's non-employee directors received grants of an aggregate of 32,348 shares of Class A restricted Common Stock. Because of his affiliation with Onex and the Company's former management arrangements with Onex (see "Certain Relationships and Related Person Transactions" above), Mr. Popatia did not receive any restricted stock grants from the Company.

In 2009, the Compensation Committee reviewed benchmark Board compensation data from Towers Watson (using a peer group established by revenue level), and the Company's peer group of listed aerospace and defense companies and decided to set Company director compensation at the 75^th percentile level to account for growth projections, the international nature of the Company's business and the desire to maintain the high quality of board appointments. In 2014, the Compensation Committee reviewed benchmark Board compensation data for Fortune 500 companies prepared by Towers Watson and decided not to make any changes to Company director compensation, although it agreed to further evaluate compensation in 2015.

Non-management directors receive an annual board retainer fee of $150,000 for their service as Board members. In 2014, the annual board retainer fee paid in respect of Mr. Popatia was paid in cash to Onex Partners Advisor LP. Other than with respect to Mr. Popatia, annual board retainer fees are paid in accordance with the terms of the Director Stock Program. At least $90,000 of the annual board retainer fee is paid in either shares of restricted Common stock or restricted stock units of the Company, which are subject to a one-year time-vesting requirement. Directors have the option to receive the remainder of their compensation in cash, restricted stock or restricted stock units. In addition to the $150,000 annual board retainer fee, directors may also receive an additional annual discretionary grant of $15,000 in equity compensation per director. Non-management directors who serve on any of the Board's committees receive additional individual cash retainer fees. The chairman of the Board receives an additional annual retainer fee of $40,000, the chairman of the Audit Committee receives an additional annual retainer fee of $15,000, the chairman of each of the Board's other committees receives an additional annual retainer fee of $10,000, each non-management director who serves on the Audit Committee receives an additional annual retainer fee of $12,000 and each non-management director who serves on other committees receives an additional annual retainer fee of $8,000 per committee. No additional fees are paid for attending Board or committee meetings. The annual board retainer fees and additional individual retainer fees are payable quarterly in arrears to all directors who have served the full quarter ended prior to the date of payment. No additional or other compensation is paid to the Company's executive officers who are also members of the Board. All directors are reimbursed for their out-of-pocket expenses incurred in connection with their director services. Occasionally, certain perquisites or personal benefits are provided to non-management directors under the same general standards as perquisites or personal benefits are provided to the Company's executive officers. Perquisites and personal

COMPENSATION OF NON-MANAGEMENT DIRECTORS

benefits have been provided to non-management directors and to Mr. Lawson under the standards described in the Company's Perquisite Allowance Plan, which is discussed below in the Compensation Discussion & Analysis section. All compensation paid to Mr. Lawson in his capacity as an employee of the Company is described in the executive compensation tables and narrative below under the caption "Executive Compensation". Fees earned or paid to non-management directors in 2014 are listed in the "Director Compensation for Fiscal Year 2014" table below.

The Company maintains a minimum stockholding requirement for non-employee directors, other than for any Onex-designated director (currently Mr. Popatia), who historically was deemed to be in compliance due to Onex's stock ownership. Each existing non-employee director is expected to accumulate over four years of service on the Board (beginning on the later of (i) the initial adoption of a minimum stockholding requirement in April 2009 and (ii) the initial appointment of the director to the Board) and thereafter, while serving on the Board, to continue to hold a minimum stockholding requirement in effect prior to May 2012, which was at least the greater of (1) the number of shares of the Company's Common stock with an aggregate market value of $225,000 and (2) 10,000 shares. In May 2012, the minimum stockholding requirement was increased to the greater of (1) the number of shares of the Company's Common stock with an aggregate market value of $250,000 and (2) 12,500 shares. Non-employee directors have four years after the adoption of the increased minimum stockholding requirement to accumulate the increased amount of shares. Restricted stock units held by directors are counted in determining whether the minimum stockholding requirements are satisfied. Newly appointed members of the Board are permitted four full years of service on the Board during which to attain the minimum stockholding requirement. Information regarding the current stock ownership of the Company's directors can be found below under "Stock Ownership — Information Regarding Beneficial Ownership of Principal Stockholders, Directors and Management."

STOCK OWNERSHIP

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act, or "Section 16(a)," requires that directors, executive officers and persons who own more than ten percent of any registered class of a company's equity securities, or "reporting persons," file with the SEC initial reports of beneficial ownership and report changes in beneficial ownership of common stock and other equity securities. Such reports are filed on Form 3, Form 4 and Form 5 under the Exchange Act, as appropriate. Reporting persons holding the Company's stock are required by the Exchange Act to furnish the Company with copies of all Section 16(a) reports they file.

To the Company's knowledge, based solely on the Company's review of copies of these reports and written representations from such reporting persons, the Company believes that, except as stated in the two paragraphs below, all filings required to be made by reporting persons holding the Company's stock were timely filed for the year ended December 31, 2014 in accordance with Section 16(a).

Jeffrey L. Turner, who served as a member of the Board until April 30, 2014, inadvertently failed to timely report the sale on April 24, 2014 of 40,000 shares of Class A Common stock pursuant to a Rule 10b5-1 trading plan adopted by Mr. Turner on February 28, 2014. The sale of such shares was subsequently reported on a Form 4, filed on May 6, 2014.

Mr. Kapoor, the Chief Financial Officer of the Company, inadvertently failed to timely report the withholding by the Company of 9,175 shares of Class A Common stock on September 23, 2014 for the purposes of satisfying Mr. Kapoor's withholding tax obligations in connection with the vesting of shares previously granted to Mr. Kapoor under the Long-Term Incentive Plan (LTIP), under which long-term incentive awards were made prior to the adoption of the OIP. The disposition of such shares was subsequently reported on a Form 4, filed on September 26, 2014.

Proposal 1: Election of Directors

The Board is currently comprised of eleven directors. On January 27, 2015 and January 29, 2015, respectively, Tawfiq Popatia and Ivor Evans informed the Board that they have decided not to stand for reelection at the Annual Meeting. Messrs. Popatia and Evans will serve out the remainder of their respective current terms.

The Company's Corporate Governance and Nominating Committee has nominated each of the nine persons listed below for election as directors. If elected at the Annual Meeting, each of the nine nominees will hold office until the next Annual Meeting of Stockholders and until their successors are elected and qualified, or until their death, retirement, resignation or removal. The Company does not have a mandatory retirement age for its directors. All of the nominees except for John L. Plueger have served as directors of the Company since the 2014 Annual Meeting of Stockholders, and Mr. Plueger has served as a director since July 29, 2014.

Each nominee for election has agreed to serve if elected, and the Company has no reason to believe that any nominee will be unavailable to serve. If any nominee is unable or declines to serve as a director at the time of the Annual Meeting, it is the intention of the proxy holders to vote such proxy for such other person or persons as designated by the present Board to fill such vacancy. Unless otherwise instructed, the proxy holders will vote the proxies received by them "FOR" the nominees named below. A director must receive a plurality of the votes cast in person or by proxy at the Annual Meeting, entitled to vote on the matter and voted in favor thereof in order to be elected. As a result, the nine nominees receiving the greatest number of votes will be elected.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE ELECTION OF EACH OF THE NOMINEES.

Information Regarding Nominees for Election as Directors

The following sets forth certain information with respect to the nine nominees for election as directors of the Company at the Annual Meeting, based on information furnished to the Company by each nominee, and highlights the specific experience, qualifications, attributes and skills of the individual nominees that have led the Corporate Governance and Nominating Committee to conclude that each should continue to serve on the Board:

Compensation Overview

This Compensation Discussion and Analysis ("CD&A") describes the philosophy, objectives and features of the Company's executive compensation program, which is generally applicable to each of the Company's senior officers.

The Company's compensation programs are designed to reward the Company's executives for delivering both shorter-term performance results and longer-term stockholder value. Through the Company's programs, the Company is able to provide a competitive total compensation package while aligning executives' interests with those of the Company's stockholders. The following highlights the key considerations the Company's Compensation Committee considers in the development, review and approval of the Company's Named Executive Officers' ("NEOs") compensation:

Compensation Program Decisions

The Company's decisions on executive compensation reflect the Company's commitment to pay-for-performance and to increase alignment between the interests of executives and stockholders. Decisions made by the Company's Compensation Committee in 2014, as well as executive compensation changes set to become effective in 2015, are described below.

EXECUTIVE COMPENSATION

The Company's incentive compensation components for NEOs are intended to link compensation performance with the full spectrum of the Company's business goals, some of which are short-term, while others take several years to achieve.

The table below summarizes the average historical short-term incentive award payouts to all NEOs for 2014, 2013 and 2012.

*

In each of 2012 and 2013, each NEO in those years received the same short-term incentive payout as a percentage of their target, as no individualized component was included in the criteria used to determine short-term incentive payouts for those years.

Over time, the Company's incentive compensation programs have demonstrated the Company's commitment to pay-for-performance. As evidenced by the chart above, the Company's STI award payouts have historically been below the Company's targets when the Company does not meet its performance goals. As the Company's performance improved in 2014 as compared to 2013 and 2012, the Company's STI award payouts increased.

In addition, the Company's stock ownership guidelines require all senior executives to meet specific ownership targets based on position. This requirement, together with our LTI awards under the LTI program, subject these executives to the same long-term stock price volatility the Company's stockholders experience and further align the Company's executives' interests with those of its stockholders. See "Stock Ownership Guidelines" on page 35 for details.

EXECUTIVE COMPENSATION

The Compensation Committee continues to examine existing and new compensation programs and objectives to ensure that ours remain appropriate and consistent with the Company's overall philosophy and objectives.

Role of the CEO

Each year, the Company's NEOs prepare and discuss their self-evaluations with the Company's CEO, who presents a compensation recommendation for each other NEO to the Compensation Committee. These recommendations are based on the CEO's review of their performance, job responsibilities and importance to the Company's overall business strategy, as well as the Company's compensation philosophy. Although these recommendations are given significant weight, the Compensation Committee retains full discretion when determining compensation for the Company's executive officers.

The CEO also prepares a self-evaluation and presents it to the Compensation Committee.

Role of the Compensation Consultant

The Compensation Committee retains the authority to approve and monitor all compensation and benefit programs (other than broad-based welfare benefit programs). To add rigor in the review process and to inform the Compensation Committee of market trends, the Compensation Committee utilized the services of Towers Watson in 2014. Towers Watson assisted the Compensation Committee in benchmarking the Company's executive compensation and reviewing trends and regulatory implications for executive pay and developing incentive plan design alternatives. This information was also used by the Compensation Committee in establishing the Company's NEOs' base salaries and target goals for compensation plan awards.

Towers Watson is engaged by the Company's management, with the prior and ongoing approval of the Compensation Committee, and provides executive compensation consulting services that support the Compensation Committee's goal to align the interests of the Company's executive officers with those of the Company's stockholders. Towers Watson and

its affiliates did not provide any other services to the Company in 2014. The Compensation Committee has considered the factors specified by the SEC in determining that Towers Watson provides independent advice.

Mercer Human Resources Consulting is also engaged by the Company's management to provide non-executive compensation consulting services to the Company.

Consideration of Advisory Stockholder Vote on Executive Compensation

The Company believes that it is appropriate to seek the views of its stockholders on the design and effectiveness of the Company's executive compensation program. At the Company's 2014 Annual Meeting of Stockholders, the Company held its second non-binding, advisory stockholder vote on executive compensation (the Say-On-Pay vote) under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and received greater than 96% support from the votes of the Company's stockholders present, in person or by proxy, and entitled to vote on the matter. As an advisory vote, the results of this stockholder vote are not binding upon the Company; however, the Compensation Committee, which is responsible for designing and administering the Company's executive compensation program, values the opinions expressed by the Company's stockholders in their vote and considered the outcome of this vote when it made compensation decisions for the Named Executive Officers. The Compensation Committee considered the 96% stockholder vote supporting the Company's executive compensation, and accordingly decided not to make significant changes to the executive compensation that received the strong support of the Company's stockholders.

In addition, at the 2011 Annual Meeting of Stockholders, the Company's stockholders approved holding the advisory vote every three years (the Say-When-On-Pay vote), which the Company believes will allow for a meaningful evaluation period of performance against the Company's compensation practices. In accordance with the advisory vote of the Company's stockholders at the 2011 Annual Meeting of Stockholders, and as determined by the Compensation Committee and the Board, the Company will include an advisory vote on executive compensation in the Company's proxy statement every three years.

Benchmarking The Company's 2014 Executive Compensation Program

The Company's executive compensation program — total direct compensation consisting of base salary, STI awards and LTI awards — is compared to that of the Company's peers in order to determine competitive levels to support the attraction and retention of the Company's executive officers.

The Company benchmarks executive compensation against a peer group of comparably-sized (in terms of revenue) U.S.-based companies (emphasizing aerospace, defense and auto component manufacturers). The companies specified below were included in the Towers Watson peer group analyses for 2014. The graph below demonstrates that the peers represent a reasonable range of smaller and larger companies (based on revenues). There were no changes from the 2013 peer group in 2014.

Table of Contents

EXECUTIVE COMPENSATION

In addition to using such peer group to benchmark executive compensation, the Company also measures its TSR relative to this peer group to determine the degree to which the performance-based stock grants it made in 2014 vests.

For 2015, the Compensation Committee approved the addition of Ingersoll-Rand plc and L-3 Communications Holdings Inc. to the Company's peer group to accommodate the Company's anticipated continued growth. Ingersoll-Rand plc and L-3 Communications Holdings Inc. had revenues of $12.9 billion and $12.8 billion, respectively, for the year ended December 31, 2014 based on information disclosed in their respective public filings.

The Company also uses a broad survey sample for benchmarking executive compensation. In 2013, in connection with setting 2014 pay, the Compensation Committee reviewed compensation benchmarking based on national, proprietary compensation surveys. Specifically, data was prepared principally using a Towers Watson Executive Compensation custom survey including aerospace and defense, transportation, industrial manufacturing, energy and electrical equipment and services, automotive, building products and general industry companies. Comparable benchmarking was also conducted in 2014 in connection with establishing 2015 pay.

The composition of the survey group may vary somewhat from year to year based on survey participation. The survey analysis considers companies in relevant industries (aerospace and defense, machinery, auto components and electrical equipment) as well as companies in a broad array of industries when necessary to complement data limitations. Survey data were size-adjusted to approximate the Company's revenue either through regression or by limiting the survey sample to comparably-sized companies.

The Compensation Committee believes that overall executive compensation should be designed to be competitive with comparable companies, to reward effective execution of the Company's goals and the individual objectives set for its executive officers, and to recognize exceptional performance and results.

Analysis of 2014 Compensation

CEO Employment Agreement

Mr. Lawson's Employment Agreement provides for compensation as follows:

•

Initial base salary of $1,000,000, subject to adjustment from time to time (current base salary is $1,225,000)

•

Guaranteed target short-term incentive award of no less than 57.5% of base salary for 2014 performance (2014 STI target was 115% of base salary and 2015 STI target is 150% of base salary)

•

Long term incentive award equal to 400% of base salary (2014 LTI target was 435% of base salary; and 2015 LTI target is 500% of base salary)

•

Company contribution of $1,000,000 in deferred compensation credited on each of the first five anniversaries of hire date

Base Salaries

In 2014, Mr. Lawson received a 5% base salary increase in recognition of his performance in 2013 and to more closely align to the market median.

In 2014, Mr. Pilla received a base salary increase of 11% in recognition of his performance and Mr. Anderson received a base salary increase of 5% to partially offset the reduction in his target STI award described below.

Neither Mr. Coleal nor Mr. Kapoor received an increase in base salary in 2014, based on the level of their respective current compensation packages relative to the market median and, in addition with respect to Mr. Kapoor, his recent hiring by the Company in September 2013.

For 2015 base salary changes, please refer to "2015 Program Updates" on page 23.

Short-Term Incentive Awards

The Company generally targets annual incentive awards at a level that, when combined with base salaries, result in total annual compensation that, subject to individual exceptions based on performance or prior positions held, is at or around the market median when target performance is met and above the market median when the Company performs well.

Each year the Board establishes performance objectives, targeted achievement levels and weighting to be used for the annual STI award determination based on a recommendation from the Compensation Committee. In 2014, the Compensation Committee enhanced the design of the STI Program to create a greater link between pay and company, program/functional group and individual performance. Under this new design, STI awards are determined based on three components: (1) Company Performance (70% weighting), (2) Program/Functional Performance (20% weighting) and (3) Individual Performance (10% weighting). Among the changes made in 2014 was a reduction of the weighting of the Company Performance component from 75% to 70% of the overall STI award, the elimination of a qualitative component of up to 25% of the overall STI award and the introduction of the Program/Functional Performance component, weighted at 20% of the overall STI award, and the Individual Performance component, weighted at 10% of the overall STI award. The Program/Functional Performance component was introduced to increase management's focus on the performance of the Company's programs and functional groups, with the goal of achieving greater alignment and accountability while continuing to drive improvements in performance. The Individual Performance component was introduced to increase alignment of compensation to individual performance goals.

The Company Performance component of each NEO's 2014 STI award is scored based on the performance of the Company as measured against three quantitative metrics adopted by the Compensation Committee: (1) EBIT, (2) revenue and (3) Free Cash Flow. The Program/Functional Performance score of each NEO's 2014 STI award equaled the average of the scores assigned to each of the Company's programs and functional groups. Each program and functional group was assigned a score based on specified performance criteria applicable to such program or functional group. These criteria consist of various financial, operational and strategic criteria as specified in more detail under "Program/Functional Performance" below. The Individual Performance component of each NEO's 2014 STI award was evaluated based on the achievement of individual performance goals.

EXECUTIVE COMPENSATION

As summarized in the table below, the new 2014 STI Program design uses a two-step approach to determine the amount of STI award payouts.

Step 1: Applying the formula

Step 2: Applying the final score:

STI Program Performance Results

Company Performance (70% weighting):

In 2014, the Company achieved its maximum performance goals for each of the metrics that comprise the Company Performance component. As a result, the Compensation Committee determined that a 2.0 score had been achieved with respect to Company Performance, representing a weighted score of 1.4. The tables below summarize the Company's performance relative to the Company Performance goals for 2014.

 

Program/Functional Performance (20% weighting):

With respect to the Program/Functional Performance component of the 2014 STI awards, each program or functional group was assigned a score based on its performance measured against the performance criteria assigned to such program or functional group. The performance of each program or functional group was measured based on several of the following criteria: cash generation, product or service quality, financial performance, product or service delivery, strategic planning or plan execution, revenue/market share and cost management. The score assigned to members of the Company's executive leadership team, including all NEOs, was the average of the scores assigned to each program or functional group, which, upon consultation with Mr. Lawson and approval by the Compensation Committee, was rounded upward from 0.793 to 0.80.

Individual Performance (10% weighting):

The Individual Performance component was added in 2014 to further align executive compensation with the Company's focus areas in any given year by establishing relevant individual performance metrics targeting those focus areas relevant

to each NEO. With respect to the measurement of the Individual Performance component for 2014 STI awards, the Compensation Committee used the following scoring criteria:

Individual Performance scores for each of the Company's NEOs in 2014, as approved by the Compensation Committee, were as follows:

Overall, each of the NEOs earned more than their target STI award for 2014 as a result of above target performance, as shown in the table below.

In 2014, no changes were made to Mr. Lawson's, Mr. Kapoor's and Mr. Coleal's STI targets based on their respective aggregate compensation packages relative to the market median. In 2014, Mr. Pilla and Mr. Anderson's STI targets were reduced to 100% of their respective base salaries, matching the STI targets of the other NEOs (other than Mr. Lawson), to more closely align their respective STI targets to the market median.

EXECUTIVE COMPENSATION

The STI awards paid in 2015 in respect of 2014 performance were paid fully in cash and are considered to have been earned in 2014. These cash awards for the Named Executive Officers are reported as 2014 compensation in the "Non-Equity Incentive Plan Compensation" column of the "Summary Compensation Table."

Effective January 30, 2015, in recognition of his exceptional performance, Mr. Lawson's 2015 STI target was increased to 150% of his base salary (assuming target performance is achieved). Effective March 20, 2015, following a change in Mr. Anderson's position from Senior Vice President, Defense and Contracts to Senior Vice President of Defense Programs, his target STI award was adjusted to 80% of his annual base salary. The STI targets of the other NEOs remain at 100% of their respective base salaries.

Long-Term Incentive Awards

LTI awards under the LTI Program are an important component of compensation, as they provide long-term, equity-based variable incentive compensation in keeping with the Company's executive compensation philosophy for the entire executive group. Prior to 2014, short-term incentive awards provided the at-risk component of the executive compensation package and the LTIP had been solely a time-based vesting plan used to retain the Company's executive leadership and reward the Company's high potential employees and tie pay to stockholder returns. In 2014, the Board, at the recommendation of the Compensation Committee, made changes to the design of the Company's long-term incentive program to include a performance-based component tied to the Company's TSR relative to the TSR of a group of the Company's peers (see Proxy Peer Group Table, page 27), while retaining awards subject to time-based vesting schedules aimed at retention. Under this new design, LTI awards consist of a time-based stock award that comprises 75% of a participant's annual LTI award, and a performance-based stock award that comprises 25% of a participant's annual LTI award, assuming target performance goals are achieved. The Compensation Committee also reduced the vesting schedule of service-based awards from four years to three years, to align with market practice, with LTI awards now vesting in three equal installments on each of the first, second and third anniversaries of the grant date.

With respect to performance-based awards under the LTI Program, the number of shares that vest with respect to a grant is determined based on the ranking of the Company's TSR, expressed as a percentile, relative to the TSR of a group of the Company's peers over a three year tracking period as compared to threshold, target and maximum performance goals. Participants are initially granted a number of unvested shares equal to the number of vested shares that the participant would be entitled to upon achievement of the target performance goal. For grants made in 2014, the tracking period runs from May 1, 2014 to April 30, 2017. For grants made in 2014, the TSR for the Company and each member of its peer group for the tracking period will be determined by calculating the percentage increase in the dividend adjusted, weighted-average closing share price for the 20-trading days ending April 30, 2017 over such weighted-average share price for the 20-trading days ending April 30, 2014. The Company's TSR percentile ranking with respect to its peer group will then be measured against threshold, target and maximum performance goals, which correspond to threshold, target and maximum vesting percentages. The table below sets forth these performance goals and vesting percentages:

If the Company's TSR percentile ranking falls between the threshold and the target performance goals or the target and the maximum performance goals, the percentage of the performance-based award that a participant will receive is interpolated on a straight-line basis. If the Company's TSR percentile ranking is below the threshold performance goal, the participant will not be entitled to any vested performance-based shares and if the Company's TSR percentile ranking is equal to or higher than the maximum performance goal, the participant will be entitled to a number of vested performance-based shares equal to 200% of the target performance-based share award. The number of vested shares a participant is entitled to increases at a higher rate as the Company's TSR moves from the threshold goal to the target goal compared to the rate of increase as the Company's TSR moves from target goal to maximum goal. That is, the straight-line interpolation used to determine the percentage of the performance-based award a participant is entitled to has a steeper incline from the threshold goal to the target goal than from the target goal to the maximum goal. This asymmetry reflects the importance the Company places on incentivizing executives to meet the Company's performance goals.

EXECUTIVE COMPENSATION

In 2014, Mr. Lawson's LTI target was increased from 400% to 435% of his base salary in recognition of his accomplished performance in 2013 and to achieve closer alignment to the market median.

The table below outlines each of the Company's NEOs' annual target LTI stock awards in 2014 (reflecting fair value as calculated in accordance with applicable accounting rules).

For 2015, the Company will retain emphasis on Company performance and stockholder value by continuing the 25% weighting tied to TSR. Beginning in 2015, LTI awards will be made in the first quarter and as a result, the three-year TSR tracking period applicable to performance-based stock grants will be aligned with the Company's fiscal year (i.e. beginning in January and ending in December), commensurate with best practices.

Effective January 30, 2015, in recognition of his exceptional performance, Mr. Lawson's 2015 LTI target was increased to 500% of his base salary. Effective March 20, 2015, following a change in Mr. Anderson's position from Senior Vice President, Defense and Contracts to Senior Vice President, Defense Programs, his target LTI award was adjusted to 100% of his annual base salary. The LTI targets of the other NEOs remain unchanged.

Other Compensation Elements

Executive Recruitment

In the past, the Company has structured a variety of compensation arrangements and approved various payments to recruit executive talent. The Compensation Committee has approved long-term incentive stock awards and cash payments designed to compensate individual executive officers for compensation that they would forgo by leaving their prior employers. No such special compensation arrangements were newly entered into with any NEOs in 2014.

EXECUTIVE COMPENSATION

Perquisites

Perquisites and other benefits represent a small part of the overall compensation package for the Company's executive officers. Beginning with fiscal year 2012, all individual perquisites for the participants were eliminated and replaced with an annual allowance of $25,000 for the Company's chief executive officer and up to $13,000 for each other participant, including each of the Company's other Named Executive Officers. Any portion of a participant's annual allowance that is not used by him or her by the end of the applicable calendar year lapses and does not carry over to the following calendar year nor is any remaining balance paid out to the participants, unless a change-in-control occurs (See "Potential Payments on Termination or Change-in-Control — Change-in-Control" on page 50). The Company's CEO administers the plan on behalf of the Board and the Compensation Committee, including designating participants and allowance amounts and ensuring that the use of perquisites is in compliance with the plan. The Board or the Compensation Committee may also increase or decrease allowance amounts at any time.

The Company's executive security procedures prescribe the level of personal security to be provided to the CEO. These security procedures are based on business related security concerns and have been assessed by an independent security consulting firm and deemed necessary and appropriate for the protection of the Company's CEO. These security procedures provide for the Company's CEO to use Company aircraft for personal travel for security reasons, and as a result, Mr. Lawson's use of the Company's aircraft represents a significant perquisite provided to Mr. Lawson in addition to those perquisites provided to him under the Company's Perquisite Allowance Plan.

The Compensation Committee will periodically review competitive market data to ensure that the Perquisite Allowance Plan is reasonable and within market practice.

Health Benefits/Retirement Plans

The Company provides its executive officers, including the Company's NEOs, benefits provided to all other salaried, non-union employees, including medical and dental insurance and tax-qualified defined contribution plan participation and matching (the Company's 401(k) plan). These benefits are important for retaining the Company's executive officers and enhancing their compensation through tax-excluded or tax-deferred vehicles. The Company's contributions to the Company's 401(k) plan on behalf of the NEOs are included in the "All Other Compensation" column of the "Summary Compensation Table" below. This plan furthers the Company's objectives of attracting and retaining well-qualified employees and executive officers as it is the Company's only active retirement plan.

In connection with the formation of the Company as a stand-alone company and the acquisition of the assets of the Company from Boeing, the Company adopted a supplemental executive retirement plan (SERP) in order to attract certain employees from Boeing. The SERP provides deferred compensation benefits to those of the Company's executive officers and certain other members of management that previously participated in Boeing's Supplemental Executive Retirement Plan for Employees of Boeing prior to the Boeing Acquisition. Also in connection with the Boeing Acquisition, the Company adopted the Pension Value Plan (PVP) for those former employees of Boeing who did not retire from Boeing by August 1, 2005. Both the SERP and the PVP are frozen plans, so no additional employees are becoming participants in the plans and no current participants are accruing any additional benefits. The PVP allowed the transfer of pension values from Boeing pension plans. The PVP is fully paid for by the Company, and the Company's employees are vested after reaching five years of service. The Company lists the benefit numbers for the Named Executive Officers in the "Pension Benefits" table and the additional narrative following that table.

Stock Ownership Guidelines

The Company maintains stock ownership guidelines for its Named Executive Officers and other senior executives to further promote alignment of management and stockholder interests. The ownership requirements (measured by value of the Company's stock required to be held) are based on a multiple of base salary tied to pay grade.

The stock ownership guidelines establish the following target levels for Company stock ownership:

​

​

​

​ 2015 Proxy Statement         35

​

---

Table of Contents

EXECUTIVE COMPENSATION

Non-employee directors are expected to own the greater of $250,000 worth of stock by market value or 12,500 shares or RSUs. Shares that satisfy the stock ownership guidelines include:

•

Shares of the Company's Class A and Class B Common stock or restricted stock units (i) owned outright either individually by an officer or as co-owner with spouse, (ii) owned in the name of any of the officer's minor children, either outright or with the officer and/or spouse, or (iii) held in trust for the officer, the officer's spouse and/or minor children;

•

Shares of the Company's Class B Common stock granted under the Executive Incentive Plan (EIP) for which the officer has met the service requirements; and

•

Phantom shares held in the SERP.

The stock ownership guidelines require that the chief executive officer and other senior elected officers accumulate their required positions within five years of the adoption of the guidelines, or for new officers, within five years of being hired or promoted into the officer position. In addition, increases in an officer's target level resulting from salary increases or promotions are required to be achieved within five years of the event requiring the increase. The Company believes that five years provides a reasonable goal for executives to accumulate shares through earned incentive awards.

During the five-year accumulation period, the chief executive officer and other senior elected officers are expected to continuously accumulate qualifying equity until they meet the minimum stock ownership guideline. The Company reviews on an annual basis the ownership position of the chief executive officer and each of the other senior elected officers who is required to adhere to these guidelines. The Company may restrict any officer from liquidating any of his or her then-current holdings in Company stock, except for those shares which are sold to meet Company tax withholding requirements. The Company may modify or waive the requirements of the guidelines, at its discretion, if it determines that compliance would result in severe hardship for an officer.

Compensation in Connection with Termination of Employment

The Company believes that competitive severance protection is an appropriate incentive in attracting and retaining talent. The Company has provided for termination compensation through certain individual employment agreements in the form of salary and benefit continuation for a moderate period of time following involuntary termination of an executive officer's employment. The Company has also agreed to individual severance arrangements at the time of termination of employment, taking into account the specific facts and circumstances surrounding termination, including other compensation available at such time. The Company also considers the need to protect the Company's business and confidential and proprietary information through non-competition, non-solicitation and similar agreements, and the desire to provide for effective transitions between departing executives and continuing or new management.

You can find additional information regarding the Company's practices in providing compensation in connection with termination of employment and change-in-control under the heading "Potential Payments on Termination or Change-in-Control" below.

Compensation in Connection with Change-In-Control

The Company maintains several programs of broad application that are designed to provide compensation in connection with the termination of employment or a change-in-control of the Company. Specifically, the Company's STI awards, LTIP awards (made prior to the adoption of the OIP), LTI awards and Perquisite Allowance Plan provide for certain compensation in connection with a change-in-control of the Company as discussed below under "Potential Payments Upon Termination or Change-in-Control — Change-in-Control."

Short-Term Incentive Awards

Upon the occurrence of a change-in-control of the Company each STI award participant who is employed by the Company on the date of the change-in-control or who was terminated without cause within 90 days prior to the change-in-control will be entitled to receive an award of cash in an amount equal to the full-year STI award that such participant would have been entitled to receive for such year had the target performance metrics established for such year been met.

With respect to long-term incentive awards made prior to the adoption of the OIP, upon the occurrence of a change-in-control of the Company (i) each long-term incentive award participant who is employed by the Company on the date of the change-in-control or who was terminated without cause within 90 days prior to the change-in-control will be entitled to receive an award of cash in an amount equal to the value of the full-year long-term incentive award that would have been made to such participant within the 12-month period following the change-in-control if not for the occurrence of the change-in-control and (ii) any outstanding unvested long-term incentive award shares previously granted to each such participant will vest immediately.

With respect to LTI Program participants, except as otherwise provided in a participant's award agreement, the unvested LTI awards of a participant who is employed by the Company on the date of a change-in-control, or whose employment was involuntarily terminated by the Company (other than for cause) within the ninety (90) days preceding a change-in-control, became fully vested upon a change-in-control and the participant will also receive a cash award equal to the dollar value of the LTI award that would have been made to the participant in the ordinary course of business within the 12-month period following the date of the change-in-control based on the participant's annual base pay in effect on the date of the change-in-control. The foregoing notwithstanding, if the vesting of an unvested LTI award is subject to performance conditions, the vested portion will, at the discretion of the Compensation Committee, be determined based upon actual performance through the date of the change-in-control or, if the Compensation Committee determines that measurement of actual performance cannot be reasonably assessed, the assumed achievement of target performance.

Perquisite Allowance Plan

The Perquisite Allowance Plan provides that, in the event of a change-in-control of the Company, each participant will receive a cash award equal to any remaining unused portion of his or her allowance for the year in which the change-in-control occurs, plus an amount equal to the participant's full allowance for the calendar year in which the change-in-control occurs, which is intended to enable the employee to transition to self-funding.

Accounting and Tax Treatment of Compensation

Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code"), imposes a $1 million limit on the amount that a public company may deduct for compensation paid to a company's chief executive officer or any of a company's three other most highly compensated executive officers (other than its chief financial officer) who are employed as of the end of the year. This limitation does not apply to compensation that meets the requirements under Section 162(m) for "qualifying performance-based" compensation (i.e., compensation paid only if the individual's performance meets pre-established objective goals based on performance criteria approved by stockholders).

The Company believes that it is important to preserve flexibility in administering compensation programs in a manner designed to promote varying corporate goals. Accordingly, the Company has not adopted a policy that all compensation must qualify as deductible under Section 162(m), and not all amounts currently paid under the Company's compensation programs qualify as performance-based compensation that is excluded from the limit on deductibility. The OIP permits the Company to make short-term and long-term incentive awards that meet the performance-based criteria to allow such awards to be excluded from the limitation on deductibility.

The Company has adopted FASB's authoritative guidance on stock-based compensation accounting, which generally requires companies to measure the cost of employee and non-employee services received in exchange for an award of equity instruments based on the grant-date fair value and to recognize this cost over the requisite service period or immediately if there is no service period and there are no other vesting requirements. The notes to the Company's consolidated financial statements, included in the Company's Annual Report on Form 10-K for fiscal year 2014 filed with the SEC, contain further information concerning the Company's policies with respect to FASB's authoritative guidance on stock-based compensation accounting.

The following table sets forth the grant date fair value of the time-based and performance-based LTI awards of restricted stock made under the OIP in 2014:

Values for the performance-based LTI awards are based on the probable ranking of the Company's TSR relative to the TSR of a group of the Company's peers.

The grant date fair value of $45.04 for the performance-based LTI awards was determined using a Monte Carlo simulation model. The value was determined using the historical stock price volatilities of the companies in the Company's peer group over the most recent three-year period, assuming dividends for each company are reinvested on a continuous basis and a risk-free rate of interest of 0.89%.

The maximum grant date fair values of the performance-based share grants made under the OIP in 2014, assuming a 200% maximum payout, are as follows:

(13)

Represents cash compensation earned by each Named Executive Officer under the STIP for fiscal years 2012 and 2013 and under the STI program under the OIP for fiscal year 2014.

(14)

Represents the aggregate increase in the actuarial present value of the respective executive officer's interest under the Company's Pension Value Plan. In 2013, since the value of the benefits payable to Mr. Pilla under the Pension Value Plan decreased by $55,841, no increase was recorded. There were no above-market earnings on Mr. Pilla's interest under the Company's Deferred Compensation Plan.

(15)

"Personal airplane usage", as referenced in footnote 16 and 17, is included in All Other Compensation as a perquisite, and consists of the incremental cost to the Company of personal usage of its corporate airplane. The incremental cost to the Company for personal airplane usage is calculated based on a methodology that includes the weighted average cost of fuel, maintenance expenses, parts and supplies, landing fees, ground services, catering and crew expenses associated with such use, including those associated with "deadhead" flights related to such use. Because the corporate airplane is used primarily for business travel, the methodology excludes fixed costs that do not change based on usage. Fixed costs include pilot salaries, the purchase or lease costs of the airplane and the cost of maintenance not related to personal travel. Executives, their families and invited guests occasionally fly on the corporate airplane as additional passengers on business flights. In those cases, the aggregate incremental cost to the Company is a de minimis amount, and as a result, no amount is reflected in the Summary Compensation Table. Executives, directors, their families and invited guests also occasionally fly on the corporate airplane as additional passengers on personal flights that are attributed to another executive, in which case the entire incremental cost is allocated to the executive who arranged for the personal flight. The Company does not grant bonuses to cover, reimburse or otherwise "gross-up" any income tax owed for personal travel on the corporate airplane.

(16)

Includes (a) financial professional services, (b) residential security lighting, (c) personal use of country club membership paid for by the Company, (d) $57,908 for personal airplane usage, (e) $16,951 for Company contributions to defined contribution plans, (f) $1,000,000 for Company contributions to non-qualified deferred compensation plan, and (g) $2,612 for Company contributions toward life insurance coverage.

Pension Benefits

The following table presents information concerning benefits received under the Company's Pension Value Plan by the Named Executive Officers during the fiscal year ended December 31, 2014.

Effective June 17, 2005, pension assets and liabilities were spun-off from three of Boeing's qualified plans (each, a "Prior Plan") into four Spirit qualified plans for each Spirit employee who did not retire from Boeing by August 1, 2005. Each Prior Plan was frozen as of June 16, 2005, for future service credits and pay increases. Effective December 31, 2005, all four qualified plans were merged together into the Spirit AeroSystems Holdings, Inc. Pension Value Plan ("PVP").

EXECUTIVE COMPENSATION

One of the Company's Named Executive Officers, Mr. Pilla, is a participant in the PVP. The Company's other four Named Executive Officers were not employees of Boeing who joined the Company at the time of the Boeing Acquisition. Benefits under the PVP applicable to Mr. Pilla are based upon a Prior Plan benefit plus a Cash Balance benefit. An actuarial determination of the Prior Plan benefit was completed by Boeing based on service and final average pay through December 31, 1998, and indexed for changes in base pay through June 16, 2005. The Prior Plan amounts are payable as a life annuity beginning at normal retirement (age 65), with the full benefit payable upon retirement on or after age 60. Under the Cash Balance benefit formula, employees received Benefit Credits based on their age at the end of each plan year through June 16, 2005. The annual Benefit Credit was a specified percentage of eligible pay, ranging from 3% at ages younger than 30 to 11% upon reaching age 50. Eligible pay included base pay and executive incentive pay, limited to Code Section 401(a)(17) limits. The Benefit Credits ceased upon freezing of the Prior Plan; however, employees continue to receive Interest Credits each year. The Interest Credits for each year are based on the 30-year Treasury Rate as of November of the prior year, with a minimum of 5.25% and maximum of 10%. The Cash Balance account is converted to a life annuity upon an active employee's retirement using a factor of 11.

The PVP is fully paid for by the Company and employees are vested after reaching three years of service. Vesting service continues to accumulate after June 16, 2005 for continued employment. Mr. Pilla is fully vested in his benefits.

The normal retirement age under the PVP is 65. There are various early retirement ages allowed under the plan for the various benefits provided to employees. A portion of the Prior Plan benefit is reduced by 2% for each year that benefits commence prior to age 60. Mr. Pilla is currently 55 years of age. Projected annual benefits payable upon retirement at age 60 are $47,154 for Mr. Pilla. If he retires at age 65, the annual benefit amount is $51,633.

For purposes of the calculations shown in the "Pension Benefits" table, the Company assumes that the Named Executive Officer elects a single life annuity form of payment. The present value determination is based on the RP2000 Sex Distinct Mortality Table projected to 2018 with white collar adjustment and a 3.99% discount rate. The Interest Crediting Rate used in the calculations is 5.25% for each future year. The present values were calculated assuming the Named Executive Officer retires and commences receipt of benefits at age 60, or December 31, 2014, if later.

The Company also maintains the SERP, which provides supplemental, nonqualified retirement benefits to executives who (1) had their benefits transferred from a Boeing nonqualified plan to the SERP and (2) did not elect to convert their SERP benefit into phantom shares as of June 17, 2005. Benefits under this plan were also frozen as of the date of the Boeing Acquisition. There are no SERP annuity benefits presently payable to the Named Executive Officers.

Other Retirement Benefits

The Company sponsors the Spirit AeroSystems Holdings, Inc. Retirement & Savings Plan ("RSP"), a qualified plan covering certain eligible employees. Under the RSP, the Company makes a matching contribution of 75% of the employee's contributions to a maximum 6% of compensation match based on employee contributions of 8% of compensation. Compensation for this plan is base pay, subject to compensation limits prescribed by the IRS. The matching contributions are immediately 100% vested.

Non-matching contributions, based on an employee's age and vesting service, are made at the end of each calendar year for certain employee groups. Each Named Executive Officer is eligible for these contributions for each year that he (1) is employed by the Company as of December 31 and (2) receives a year of vesting service. If age plus vesting service totals less than 60, employees receive 1.5% of base salary as a non-matching Company contribution; if age plus vesting service totals at least 60 but less than 80, employees receive 3% of base salary; and if age plus vesting service totals at least 80, employees receive a 4.5% of base salary contribution. These contributions are 25% vested at two years, 50% vested at three years, 75% vested at four years, and 100% vested at five years of vesting service, which includes prior service with Boeing.

In addition, the Company contributes amounts for certain employees eligible for transition contributions. In general, employees who became the Company's employees on June 17, 2005, did not retire from Boeing, and had at least five years of vesting service as of that date are eligible for such transition contributions. Mr. Pilla is the Company's only Named Executive Officer entitled to such transition contributions. Transition contributions are paid at the end of each calendar year for a number of years equal to the employee's vesting service as of June 17, 2005, up to a maximum of 15 years. For vesting service from 5-9 years, such transition contribution is 1.5% of base salary per year; for 10-14 years, it is 2.5% of base salary per year; and for at least 15 years, it is 3.5% of base salary per year. These contributions become vested after three years of vesting service with the Company or upon reaching age 60, if earlier.

EXECUTIVE COMPENSATION

RSP matching contributions, non-matching contributions and transition contributions are included in the "Summary Compensation Table" above as a component of "All Other Compensation" for the eligible Named Executive Officer.

The Company makes post-retirement medical and dental coverage available to all employees who retire from the Company at age 55 or later, provided they have at least 10 years of service and participated in the Company's medical and dental plans prior to retirement. Employees pay the full cost of coverage for this benefit — the Company does not pay any subsidy. For employees previously employed by Boeing whom the Company hired as of June 17, 2005, the Company provides subsidized post-retirement medical coverage upon early retirement after attaining age 62 with 10 years of service. Subject to paying the same employee premiums as an active employee, early retirees may maintain their medical coverage until attainment of age 65 or Medicare eligibility due to disability prior to age 65. The subsidized medical coverage will be available to Mr. Pilla, provided he retires from the Company at or after age 62.

Nonqualified Deferred Compensation

The following table presents information concerning each of the Company's defined contribution or other plans that provides for the deferral of compensation of the Company's Named Executive Officers on a basis that is not tax qualified.

The Company also sponsors the Spirit AeroSystems Holdings Deferred Compensation Plan ("DCP"). This nonqualified plan allows eligible employees to defer receipt of a portion of their base salary or short-term incentive compensation. In addition, the DCP allows for discretionary contributions by the Company into a separate account in the DCP. Deferred amounts and amounts which the Company contributes to its employees' accounts in the DCP are credited with a rate of return equal to 120% of the applicable federal long-term rate for October of the prior fiscal year. For 2014, the interest crediting rate was 4.2%. Accumulated amounts are payable to the participant in either a lump sum or installments upon separation from employment with the Company, or at the end of the deferral period selected by the participant upon enrollment in the DCP.

Contributions to the DCP labeled as "Registrant Contributions" (if any) are included as part of "All Other Compensation" in the "Summary Compensation Table". There were no "above-market" earnings (defined by SEC rule as that portion of interest that exceeds 120% of the applicable federal long-term rate) under the plan during fiscal year 2014, as the Company used 120% of the applicable federal long-term rate to determine the amounts to be contributed.

Potential Payments Upon Termination or Change-in-Control

Termination of Employment

Spirit maintains employment agreements with certain Named Executive Officers, pursuant to which certain payments may be made, or benefits provided, in the event the executive's employment is terminated; however, the provisions in the employment agreements of Messrs. Anderson and Coleal pursuant to which such payments would be made upon termination are no longer applicable. Mr. Pilla's employment agreement contains no such provisions providing for payments or benefits in such circumstances. In addition, upon termination of employment, amounts may become payable to the Named Executive Officers pursuant to the SERP, the DCP and the STI Program under the OIP.

Employment Agreements

Employment agreements entered into by Spirit with Messrs. Lawson and Kapoor provide for varying types and amounts of payments and additional benefits upon termination of employment, depending on the circumstances of the termination.

EXECUTIVE COMPENSATION

•

Voluntary Termination by the Executive. In the event of voluntary termination by the executive, salary and benefits are continued only through the date of termination.

•

Involuntary Termination by Spirit for Cause. In the event of involuntary termination by Spirit for cause, no amounts are payable by reason of termination, other than salary and benefits payable through the date of termination. Generally, Messrs. Lawson's and Kapoor's employment agreements define termination for "cause" to mean (1) the executive committing a material breach of his employment agreement or acts involving fraud, dishonesty, disclosure of confidential information, or the commission of a felony, or direct and deliberate acts constituting a material breach of his duty of loyalty to Spirit; (2) the executive willfully or continuously refusing to or willfully failing to perform the material duties reasonably assigned to him by the Board or the Company, as applicable, where the refusal or failure does not result from a disability (as discussed below); (3) material underperformance, as reflected in two consecutive performance reviews provided no less than six months apart; or (4) the inability of the executive to obtain and maintain appropriate United States security clearances. In the case of Mr. Kapoor's employment agreement, crimes of moral turpitude are also grounds for termination for "cause." Each of Mr. Lawson's and Mr. Kapoor's employment agreements states that his termination is not deemed to be for cause unless and until there shall have been delivered to the executive a copy of a resolution to that effect, duly adopted by the Board.

•

Involuntary Termination by Spirit without Cause or Termination by Executive for Good Reason. In the event Mr. Lawson's employment terminates due to involuntary termination by Spirit without cause or termination by Mr. Lawson for good reason, Spirit will (i) continue to pay Mr. Lawson an amount equal to his base salary in effect immediately before termination of his employment for a period of 12 months, or if such termination is during Mr. Lawson's initial three-year employment term (which commenced on April 6, 2013), the longer of the remainder of the employment period and 12 months, (ii) pay the costs of COBRA medical and dental benefits coverage after termination for a period of 12 months, (iii) cause any unvested STIP shares held by Mr. Lawson to become immediately vested, and (iv) cause the following LTIP and LTI award shares to be vested, to the extent not previously vested: (A) 100% of shares awarded in Mr. Lawson's 2013 LTIP grant, (B) 66²/3% of shares awarded in Mr. Lawson's 2014 LTI award and (C) 33¹/3% of shares awarded in Mr. Lawson's 2015 LTI award. Also in the event of such a termination, Mr. Lawson will be entitled to accelerated vesting of all then-unvested shares of restricted stock granted to him under his employment agreement as a sign-on bonus, and Spirit will credit Mr. Lawson's DCP account with all remaining amounts that he would have been credited pursuant to his employment agreement as if he had remained employed until the fifth anniversary of the effective date of his employment agreement (with Mr. Lawson's employment agreement providing for crediting of $1,000,000 on each of the first five anniversaries of the effective date of his employment).

In the event Mr. Kapoor's employment terminates due to involuntary termination by Spirit without cause or termination by Mr. Kapoor for good reason, he will be entitled to termination benefits, pursuant to which Spirit will (i) continue to pay Mr. Kapoor an amount equal to his base salary in effect immediately before termination of his employment for a period of 12 months, or if such termination is during Mr. Kapoor's initial three-year employment term (which commenced on September 23, 2013), the longer of the remainder of the employment period (but not to exceed 24 months) and 12 months, (ii) pay the costs of COBRA medical and dental benefits coverage after termination for a period of 12 months, (iii) cause any unvested STIP shares held by Mr. Kapoor to become immediately vested, (iv) if such termination is during Mr. Kapoor's initial three-year employment term, cause the following LTI award shares to be vested, to the extent not previously vested: (A) 66²/3% of shares awarded in Mr. Kapoor's 2014 LTI award and (B) 33¹/3% of shares awarded in Mr. Kapoor's 2015 LTI award, and (v) pay any unpaid portion of Mr. Kapoor's cash sign-on bonuses awarded pursuant to his employment agreement. Also in the event of such a termination, any of the signing bonus shares that were awarded to Mr. Kapoor under the LTIP or OIP pursuant to his employment agreement that are not fully vested at the time of such termination will automatically vest in full at such time.

Generally, any termination of the employment agreements with Messrs. Lawson and Kapoor by Spirit other than for cause, death or disability constitutes a termination without cause. Termination due to expiration of the applicable employment period without renewal also constitutes a termination without cause.

Under Messrs. Lawson's and Kapoor's employment agreements, termination by the executive for "good reason" is defined to mean voluntary termination of employment by the executive within 90 days after the following conditions (provided that notice is given to Spirit and the conditions remain uncured after a specified amount of time thereafter): (i) within three years after commencement of employment, the executive is assigned to a position that is a "diminished position"; or (ii) upon a change-in-control of Spirit or within twelve months thereafter, the executive is not offered

EXECUTIVE COMPENSATION

continued employment with Spirit or a successor in a position other than a "diminished position." A position is defined to be a "diminished position" if it reflects: (i) a material diminution in base compensation; (ii) a material diminution in authority, duties or responsibilities; (iii) a change in reporting requirements; (iv) relocation of the Company's principal office to a location greater than 50 miles from Wichita, Kansas; or (v) any action or inaction with respect to the terms and conditions of the applicable Named Executive Officer's employment that constitutes a material breach by Spirit of the employment agreement.

None of the Named Executive Officers' employment agreements attempt to define circumstances constituting constructive termination by Spirit. However, each of the Named Executive Officers' employment agreements are governed by Kansas law, which recognizes the concept that a resignation by the employee may constitute a constructive termination by the employer under certain circumstances.

•

Disability or Death. In the event Mr. Lawson's or Mr. Kapoor's employment terminates due to disability or death, payment of base salary continues only through the date of termination, any unvested STIP shares held by the executive on the date of termination will be immediately fully vested, and if the termination occurs within the first three years of the executive's employment, the executive would be credited with one additional year of vesting service with respect to any unvested LTIP or LTI award shares he holds on the date of termination. In addition, any unvested shares of restricted stock that were awarded to Mr. Lawson or Mr. Kapoor as a signing bonus under their respective employment agreements will be immediately fully vested upon such executive's termination due to death or disability. For purposes of Mr. Lawson's employment agreement, disability means the inability to render the services required under the employment agreement for a period of 180 days during any 12-month period, and for purposes of Mr. Kapoor's employment agreement, disability means total disability as evidenced by commencement of benefits under the Company's long-term disability plan (or, if the executive is not a participant in the Company's long-term disability plan, when he would have been eligible for benefits using the standards set forth in that plan).

The continued receipt of payments and benefits by either Mr. Lawson or Mr. Kapoor upon termination of his employment due to involuntary termination without cause is conditioned upon satisfaction, for a period of the longer of 12 months after termination of employment or the period in which Spirit is continuing to pay such executive his base salary, of a covenant not to compete and a covenant not to solicit customers or employees of Spirit. Such period extends to 24 months in the event of a termination of employment for any reason other than involuntary termination without cause.

Spirit's employment agreements with Mr. Anderson and Mr. Coleal provide for certain benefits upon termination of such executives' employment by Spirit without cause within two years after the effective date of their respective agreements, which has since passed for these executives. Mr. Pilla's employment agreement does not provide for any payments or benefits upon termination. Accordingly, upon termination of their employment, salary and benefits continue only through the date of termination, except as provided under the SERP and/or DCP, as described below.

Supplemental Executive Retirement Plan

Pursuant to the SERP, Mr. Pilla holds 16,023 phantom stock units. Upon a "Change-in-Control" or "Separation from Service" following a "Liquidity Event" (each as defined in the SERP), Mr. Pilla is entitled to receive payment with respect to each of those phantom stock units in an amount equal to (i) the market value of one share of Class B Common stock in the Company (determined as of the business day immediately preceding the date of payment), plus (ii) the amount of all dividends (other than stock dividends), if any, actually paid on one share of Class B Common stock in the Company during the period from June 16, 2005 through the date payment is made. A "Change-in-Control" under the SERP is a transaction pursuant to which a person, or more than one person acting as a group (in either case, however, excluding Onex), acquires (i) more than 50% of the total voting power of the stock of the Company (including, but not limited to, acquisition by merger, consolidation, recapitalization, reorganization, or sale or transfer of the Company's equity interests), or (ii) all or substantially all of the assets of the Company or Spirit and all or substantially all of the proceeds from such transaction are distributed to the stockholders of the Company. A "Separation from Service" under the SERP is defined as the applicable employee's termination of employment, for any reason, including death, disability, retirement, discharge (with or without cause) or voluntary termination. A "Liquidity Event" under the SERP includes the initial public offering consummated by the Company on November 27, 2006. Thus, Mr. Pilla will be entitled to payment under the SERP with respect to his phantom stock units upon any future "Change-in-Control" or "Separation from Service." Payment under the SERP will be made in a single lump sum in cash or stock as soon as administratively practicable following the change-in-control or separation from service.

EXECUTIVE COMPENSATION

Deferred Compensation Plan

Pursuant to the DCP, the Named Executive Officers participating in the DCP are entitled to receive payment of amounts credited to their deferred compensation accounts under the DCP upon a separation from service with Spirit and its affiliates. Amounts are payable in a lump sum or in up to 15 annual installment payments, as elected by each participant (subject to the terms and conditions set forth in the DCP).

Payment to a participant of any employer matching or discretionary contributions made under the DCP is subject to satisfaction by the participant of noncompetition and nonsolicitation requirements during the term of the participant's employment and for so long as the participant receives payments under the DCP and confidentiality requirements. In addition, the participant must not have been terminated for cause.

For purposes of the DCP, a termination for cause means a separation from service involving (i) gross negligence or willful misconduct in the exercise of the executive's responsibilities; (ii) breach of fiduciary duty with respect to Spirit; (iii) material breach of any provision of an employment contract; (iv) the commission of a felony crime or crime involving moral turpitude; (v) theft, fraud, misappropriation or embezzlement (or suspicion of the same); (vi) willful violation of any federal, state or local law (except traffic violations and other similar matters not involving moral turpitude); or (vii) refusal to obey any resolution or direction of the executive's supervisor or the Board. The Compensation Committee determines, in its sole discretion, whether an executive has incurred a separation from service that is a termination for cause under the DCP.

Short Term Incentive Program

Under the STI Program, in the event of a "Qualifying Retirement" by a STI Program participant, (i) if such Qualifying Retirement occurs 90 days or more after the beginning of the relevant plan year, the participant will be entitled to receive a prorated STI award (based on the portion of such year that has elapsed prior to such participant's Qualifying Retirement), paid in cash, based on the full-year STI award performance metrics actually achieved for such year and (ii) any outstanding STI awards previously granted to such participant in the form of unvested shares will vest immediately.

Summary Tables and Information

The following summarizes the amounts potentially payable upon termination of employment for Messrs. Lawson, Kapoor and Pilla, assuming termination occurred on December 31, 2014. For purposes of presenting amounts payable over a period of time (e.g., salary continuation), the amounts are shown as a single total but not as a present value (i.e., the single sum does not reflect any discount). Messrs. Anderson and Coleal would not be entitled to any payments upon termination other than salary and benefits through the date of termination.

Change-in-Control

Neither the Company nor Spirit maintains a change-in-control agreement or any other similar plan or arrangement intended specifically to provide income protection for executive officers upon a change-in-control. However, several of the Company's plans provide certain benefits to executive officers in the event of a change-in-control.

Under the SERP, a change-in-control may result in payment of amounts with respect to phantom stock granted under the SERP, as further described above under "Termination of Employment — Supplemental Executive Retirement Plan". Under the EIP, a change-in-control may provide participants the opportunity to acquire an interest in restricted shares granted under the EIP and/or may increase the opportunity to acquire an interest in restricted shares upon a future liquidity event.

Under the LTIP, a change-in-control of the Company will entitle the participants in those plans (which includes each Named Executive Officer) to accelerated vesting in full of any outstanding unvested shares held pursuant to the LTIP. For the LTIP, a change-in-control is (i) a transaction pursuant to which a person, or more than one person acting as a group, acquires more than 50% of the total voting power of the stock of the Company (including, but not limited to, acquisition by merger, consolidation, recapitalization, reorganization, or sale or transfer of the Company's equity interests), (ii) a merger or consolidation involving the Company in which the Company is not the surviving entity, or

EXECUTIVE COMPENSATION

(iii) a transaction that is a sale of all or substantially all of the assets of the Company or Spirit if all or substantially all of the proceeds from such transaction are distributed to the stockholders of the Company.

Under the LTI Program established under the OIP, except as otherwise provided in a participant's award agreement, the unvested LTI awards of a participant (which includes each Named Executive Officer) who is employed by the Company on the date of a change-in-control, or whose employment was involuntarily terminated by the Company (other than for cause) within the ninety (90) days preceding a change-in-control, became fully vested upon a change-in-control and the participant will also receive a cash award equal to the dollar value of the LTI award that would have been made to the participant in the ordinary course of business within the 12-month period following the date of the change-in-control based on the participant's annual base pay in effect on the date of such change-in-control. The foregoing notwithstanding, if the vesting of such unvested LTI award is subject to performance conditions, the vested portion will, at the discretion of the Compensation Committee, be determined based upon actual performance through the date of the change-in-control or, if the Compensation Committee determines that measurement of actual performance cannot be reasonably assessed, the assumed achievement of target performance. Under the OIP, a change-in-control is defined as defined in the LTIP (as described above).

Under the STI Program established under the OIP, upon the occurrence of a change-in-control of the Company each STI award participant who is employed by the Company on the date of the change-in-control or who was terminated without cause within 90 days prior to the change-in-control will be entitled to receive an award of cash in an amount equal to the full-year STI award that such participant would have been entitled to receive for such year had the target performance metrics established for such year been met.

Under the Perquisite Allowance Plan, any of the Named Executive Officers who are employed by the Company on the date of closing of a change-in-control transaction or who were involuntarily terminated by the Company without cause during the 90-day period ending on the date of the change-in-control transaction are entitled to receive a cash award equal to (i) any remaining unused portion of the Named Executive Officer's allowance for the calendar year in which the change-in-control transaction occurs, plus (ii) an amount equal to 100% of the Named Executive Officer's allowance for the calendar year in which the change-in-control transaction occurs. The annual allowance amount for Mr. Lawson is $25,000 and is determined by Mr. Lawson (subject to increase or decrease by the Board or the Compensation Committee) for the other Named Executive Officers (not exceeding an annual amount of $13,000 per participant which is the amount determined by the Company for 2014). Under the Perquisite Allowance Plan, a change-in-control is defined as defined in the LTIP (as described above).

Summary Table

The following table summarizes the compensation that may become payable to the Company's current Named Executive Officers upon a change-in-control, assuming the change-in-control occurred on December 31, 2014.

Proposal 2:

Ratification of Selection of Independent Registered Public Accounting Firm

Overview

Ernst & Young LLP currently serves as the Company's independent registered public accounting firm, and that firm conducted the audit of the Company's accounts for fiscal year 2014. The Audit Committee has selected Ernst & Young LLP as the Company's independent registered public accounting firm for fiscal year 2015, and the Board is asking the Company's stockholders to ratify that selection. Selection of the Company's independent registered public accounting firm is not required to be submitted to a vote of the stockholders of the Company for ratification. Although the Sarbanes-Oxley Act as well as the charter of the Audit Committee require the Audit Committee to engage, retain, and supervise the Company's independent registered public accounting firm, the Board considers the selection of the independent registered public accounting firm to be an important matter of stockholder concern and is submitting the selection of Ernst & Young LLP for ratification by the Company's stockholders as a matter of good corporate practice.

If a majority of votes cast on this matter are not cast in favor of the selection of Ernst & Young LLP, the Audit Committee and the Board will reconsider the selection of such firm as the Company's independent registered public accounting firm. Even if the Company's stockholders vote on an advisory (non-binding) basis in favor of the selection, the Audit Committee may, in its discretion, direct the selection of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and the stockholders.

The Company expects that representatives of Ernst & Young LLP will be present at the Annual Meeting, will have an opportunity to make a statement, and will be available to respond to appropriate questions.

Unless otherwise instructed, the proxy holders will vote proxies received by them "FOR" the proposal. The affirmative vote of a majority of the votes of the shares of Common stock represented at the Annual Meeting is required to approve the ratification of the selection of Ernst & Young LLP as the Company's independent registered public accounting firm for fiscal year 2015.

Change in Accountants

On May 8, 2014, the Company, as approved by the Board upon recommendation of the Audit Committee, dismissed PricewaterhouseCoopers LLP as the Company's independent registered public accounting firm following the completion of a competitive process to determine the Company's independent registered public accounting firm for the fiscal year ending December 31, 2014. The Audit Committee invited several firms to participate in this process, including PricewaterhouseCoopers LLP. As a result of this process, the Board, upon recommendation of the Audit Committee, approved the appointment of Ernst & Young LLP as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2014 and on May 12, 2014, Ernst & Young LLP was so appointed by the Company.

The reports of PricewaterhouseCoopers LLP on the Company's financial statements for each of the two fiscal years ended December 31, 2013 and 2012 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During the fiscal years ended December 31, 2013 and 2012 and in the subsequent interim period through May 8, 2014, there was no "disagreement" (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) with PricewaterhouseCoopers LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to the satisfaction of PricewaterhouseCoopers LLP, would have caused PricewaterhouseCoopers LLP to make reference to the subject matter of such disagreements in connection with its reports on the financial statements for such years.

PROPOSAL 2

During the fiscal years ended December 31, 2013 and 2012 and in the subsequent interim period through May 8, 2014, there was no "reportable event" (as defined in Item 304(a)(1)(v) of Regulation S-K), except that PricewaterhouseCoopers LLP advised the Company that the Company did not maintain effective internal control over financial reporting, due to the existence of the following previously disclosed material weaknesses:

  (i)  in 2012, the Company identified a material weakness related to its contract accounting estimates for its Gulfstream G280 and G650 programs, specifically that controls over contract accounting estimates related to these programs were not operating effectively in order to ensure that (1) the bills of materials used in the accounting estimates were complete and provided a sound basis for estimating future costs and (2) the evaluation of current actual trends impacting prior estimates of supply chain and labor costs are identified and incorporated into the accounting estimates on a timely basis;

 (ii)  in 2013, the scope of the foregoing material weakness was expanded to include a failure with respect to the accuracy of the estimation of the number of production units; and

(iii)  in 2013, the Company identified a material weakness related to its contract accounting estimates for its Airbus A350 XWB Section 15 recurring program, specifically, that controls over the completeness and accuracy of the bill of materials used in the contract accounting estimates for this program were not designed effectively to ensure that the bill of materials used in the accounting estimates were accurate and provided a sound basis for estimating future costs.

During the fiscal years ended December 31, 2013 and 2012 and subsequent interim period through May 12, 2014, neither the Company, nor anyone on its behalf, has consulted Ernst & Young LLP with respect to (1) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and neither a written report nor oral advice was provided to the Company that Ernst & Young LLP concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (2) any matter that was either the subject of a "disagreement" (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a "reportable event" (as defined in Item 304(a)(1)(v) of Regulation S-K).

The Company provided PricewaterhouseCoopers LLP with a copy of the foregoing disclosure and requested that PricewaterhouseCoopers LLP furnish the Company with a letter addressed to the SEC stating whether it agreed with the foregoing disclosure and if not, stating the respects in which it did not agree. A copy of PricewaterhouseCoopers LLP's letter, dated May 13, 2014, is filed as Exhibit 16.1 to the Company's Current Report on Form 8-K filed with the SEC on May 13, 2014.

Recommendation of the Board of Directors

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE RATIFICATION OF THE SELECTION OF ERNST & YOUNG LLP AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

Report of the Audit Committee

The Board has a separately-designated standing Audit Committee, established in accordance with Section 3(a)(58)(A) of the Exchange Act. The Audit Committee assists the Board in fulfilling its oversight responsibilities by reviewing the financial reports and other financial information provided by the Company to any governmental body or the public, the Company's systems of internal controls regarding finance, accounting, legal and regulatory compliance, and ethics that the Board and the Company's management have established, and the Company's auditing, accounting and financial reporting processes generally. The Audit Committee annually selects the Company's independent registered public accounting firm and evaluates the independence, qualifications, and performance of the Company's internal auditors and the independent registered public accounting firm. The Audit Committee establishes procedures for and oversees receipt, retention, and treatment of complaints received by the Company regarding accounting, internal control, or auditing matters and the confidential, anonymous submission by the Company's employees of concerns regarding questionable accounting or auditing matters.

The Audit Committee has reviewed and discussed with management and the independent registered public accounting firm the Company's audited financial statements as of and for the year ended December 31, 2014, as well as the representations of management regarding the Company's internal control over financial reporting. The Audit Committee discussed with the Company's internal auditors and independent registered public accounting firm the overall scope and

PROPOSAL 2

plans for their respective audits. The Audit Committee met with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, the evaluation of the Company's internal controls, management's representations regarding internal control over financial reporting, and the overall quality of the Company's financial reporting.

The Audit Committee has discussed with the independent registered public accounting firm all items required by the standards of the Public Company Accounting Oversight Board, including the Statement on Auditing Standards, No. 61, as amended by AICPA, Professional Standards, Vol. 1, AU section 380, as adopted by the Public Company Accounting Oversight Board in Rule 3200T, Communication with Audit Committees. The Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the audit committee concerning independence, and the Audit Committee has discussed with the independent registered public accounting firm its independence from the Company and its management.

The Audit Committee has relied on management representations that the financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America and on the opinion of the independent registered public accounting firm included in their report to the Company's audited financial statements.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements referred to above be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014, for filing with the SEC, and selected Ernst & Young LLP as the Company's independent registered public accounting firm for fiscal year 2015.

Proposal 3:

Approve the Proposed Fourth Amended and Restated Bylaws of the Company to Delete Certain Obsolete Provisions and Make Minor Changes to Certain Provisions of the Company's Existing Bylaws

The Company's Third Amended and Restated Bylaws (the "Existing Bylaws") currently includes a number of obsolete provisions relating to:

•

the requirements of the Special Security Agreement (the "Special Security Agreement") among Onex Corporation, the Company and the DoD, which had been in place because the Company was under foreign ownership, control or influence ("FOCI") while possessing a DoD facility security clearance;

•

the Company's Government Security Committee, which was required under the Special Security Agreement; and

•

certain rights associated with Class B Common stock applicable as long as the number of shares of Class B Common stock outstanding represents at least 10% of the total number of shares of all common stock outstanding;

In June 2014, as a result of the conversion by Onex of shares of Class B Common stock into Class A Common stock and the sale of such converted shares, the number of shares of Class B Common stock outstanding was reduced below 10% of the total number of shares of all Common stock of the Company outstanding and Onex ceased to control a majority of the Company's voting common stock. As a result, the Company was no longer under majority FOCI, and applied to the DoD to terminate the Special Security Agreement. On October 3, 2014, the DoD formally notified the Company that the Special Security Agreement was officially terminated. On October 27, 2014, the Board disbanded the Government Security Committee, as the Company was no longer required to retain this committee following the termination of the Special Security Agreement.

As a result of these developments, a number of provisions in the Company's Existing Bylaws are no longer applicable or relevant. Deleting those provisions simplifies the Company's bylaws and enhances readability. The Company also proposes to make certain other minor changes to clarify certain provisions, enhance readability and eliminate redundancies.

The proposed changes to the Existing Bylaws consisting of the deletion of Sections 2.2(b), 2.2(c), 2.9(c), 2.9(d), 2.14, 3.2 and 3.3 and certain portions of Sections 2.4(b), 2.6, 2.10, 2.11, 3.1, 4.1, 4.8 and 6.4 are being made to remove provisions that are no longer required due to the termination of the Special Security Agreement and the disbanding of the Government Security Committee. The proposed changes to the Existing Bylaws consisting of the deletion of certain portions of Sections 1.4, 1.5 and 1.7 are being made to remove provisions relating to rights associated with Class B Common stock that are no longer applicable as a result of the number of shares of Class B Common stock outstanding representing less than 10% of the total number of shares of all common stock outstanding. The proposed changes to the Existing Bylaws consisting of the deletion of certain portions of Section 1.7 and 3.4 and the addition of certain clarifying language to Section 1.7 are being made to clarify certain provisions, enhance readability and eliminate redundancies. In addition, the proposed changes to the Existing Bylaws consisting of the deletion of certain portions of Section 4.5 are being made due to the fact that the Company views its Vice President, Corporate Controller as the Company's principal accounting officer. None of these proposed changes are intended to have any adverse effect on the rights of the Company's stockholders.

The Board has approved each of the proposed changes to the Existing Bylaws described above, subject to approval by the Company's stockholders. Under the Existing Bylaws, only the Company's stockholders may amend or repeal Sections 2.4, 2.9(c) and 2.11. Although the Board has the authority to effect the other proposed changes to the Existing Bylaws described above without stockholder approval, the Company is seeking the approval by the Company's stockholders of all of the proposed changes to the Existing Bylaws.

A copy of the proposed Fourth Amended and Restated Bylaws (the "Proposed Bylaws") is attached to this Proxy Statement as Appendix B. The proposed changes to the Existing Bylaws are reflected in the form of markings which

APPENDIX A

NON-GAAP FINANCIAL MEASURES

Adjusted EBIT, Adjusted Free Cash Flow and Adjusted Diluted Earnings (Loss) Per Share are supplemental measures of the Company's performance that are not required by, or presented in accordance with, generally accepted accounting principles in the United States ("GAAP"). None of Adjusted EBIT, Adjusted Free Cash Flow and Adjusted Diluted Earnings (Loss) Per Share is a measurement of the Company's performance under GAAP and should not be considered as an alternative to net income (loss), Diluted Earnings (Loss) Per Share or any other financial measures derived in accordance with GAAP or as an alternative to cash provided by operating activities as a measure of liquidity.

As presented in this Proxy Statement, Adjusted EBIT is defined as earnings before interest and taxes as adjusted to exclude certain non-operating and/or non-recurring items which the Company believes are not reflective of operating performance. Adjusted Free Cash Flow is defined as cash provided by operating activities, less capital expenditures, as adjusted to exclude certain non-operating and/or non-recurring items and capital expenditures which the Company believes are not reflective of operating performance. Adjusted Diluted Earnings (Loss) Per Share is defined as diluted earnings (loss) per share as adjusted to exclude the impact of certain non-operating and/or non-recurring items which the Company believes are not reflective of operating performance.

The Company presents Adjusted EBIT, Adjusted Free Cash Flow and Adjusted Diluted Earnings (Loss) Per Share because it considers them important supplemental measures of the Company's performance and believes they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. The Company also used Adjusted EBIT and Adjusted Free Cash Flow to determine, in part, the compensation paid to the Company's NEOs under the STI Program (see "Executive Compensation — Compensation Discussion & Analysis — Analysis of 2014 Compensation — Short-Term Incentive Awards" on page 30). Since Adjusted EBIT, Adjusted Free Cash Flow and Adjusted Diluted Earnings (Loss) Per Share are not measures determined in accordance with GAAP and thus are susceptible to varying interpretations and calculations, these measures may not be comparable to similarly titled measures used by other companies.

THIRDFOURTH AMENDED AND RESTATED
BYLAWS
OF SPIRIT AEROSYSTEMS HOLDINGS, INC.
(the "Corporation")
adopted on April 27, 201022, 2015

1      MEETING OF STOCKHOLDERS.

1.1    Annual Meeting of Stockholders.    An annual meeting of stockholders shall be held in each year on such date and at such time as may be set by the board of directors of the Corporation (the "Board") (or by an officer of the Corporation authorized to do so by the Board) for the purpose of electing directors and the transaction of such other business as may properly come before the meeting.

1.2    Special Meetings of Stockholders.    Special meetings of the stockholders for any purpose or purposes may be called at any time by the Board (or by an officer of the Corporation authorized to do so by the Board), the Chief Executive Officer or the Secretary. A special meeting of stockholders may also be called by the holders having a majority of the voting power of all of the Corporation's outstanding class A common stock, $0.01 par value per share (the "Class A Common Stock") and class B common stock, $0.01 par value per share (the "Class B Common Stock"), voting together as a single class. Such special meetings may not be called by any other person or persons.

At any time, upon written request of any person or persons entitled to call and who have duly called a special meeting, it shall be the duty of the Secretary to set the date of the meeting, if such date has not been set by the Board, on a day not more than 60 days after the receipt of the request, and to give due notice of such meeting to the stockholders of the Corporation. If the Secretary shall neglect or refuse to set the date of the meeting and give notice thereof, the person or persons calling the meeting may do so.

1.3    Place and Notice of Meetings of Stockholders.    All meetings of stockholders shall be held at the principal office of the Corporation unless the Board (or an officer of the Corporation authorized to do so by the Board) shall decide otherwise, in which case such meetings may be held at such location within or without the State of Delaware as the Board may from time to time direct. Written notice of the place, day and hour of all meetings of stockholders and, in the case of a special meeting, of the general nature of the business to be transacted at the meeting, shall be given to each stockholder of record entitled to vote at the particular meeting either personally or by sending a copy of the notice through the mail or by overnight courier to the address of the stockholder appearing on the books of the Corporation or supplied by him to the Corporation for the purpose of notice or by any other means, including electronic means, permitted by law. Except as otherwise provided by the Bylaws, the Certificate of Incorporation or by law, such notice shall be given not less than 10 nor more than 60 days before the date of the meeting by the Chief Executive Officer, President or Secretary. If mailed, such notice shall be deemed to be given when deposited in the United States mail, postage prepared, directed to the stockholder at such stockholder's address as it appears on the records of the Corporation. A waiver in writing of any written notice required to be given, signed by the person entitled to such notice, whether before or after the time stated, shall be deemed equivalent to the giving of such notice. Attendance of a person, either in person or by proxy, at any meeting shall constitute a waiver of notice of such meeting, except where a person attends a meeting for the express purpose of objecting to the transaction of any business because the meeting was not lawfully called or convened.

1.4    Nominations by Stockholders of Candidates for Election as Directors.    In addition to the nomination by the Board of candidates for election to the Board as hereinafter provided, candidates may be nominated by any stockholder of the Corporation entitled to notice of, and to vote at, any meeting called for the election of directors and who complies with the notice procedures set forth in this Section 1.4. Subject to the last sentence of this section, nominations, other than those made by or on behalf of the Board, shall be made in writing and shall be received by the Secretary of the Corporation not later than (a) with respect to an election of directors to be held at an annual meeting of stockholders, 120 days prior to the anniversary date of the immediately preceding annual meeting, provided that, if the date of the annual meeting is more than 30 days before or after the anniversary date of the immediately preceding annual meeting, the stockholder nomination shall be received within 15 days after the public announcement by the Corporation of the date of the annual meeting, and (b), with respect to an election of directors to be held at a special meeting of stockholders, the close of business on the 15th day following the date on which notice of such meeting is first given to

Such nomination shall contain the following information to the extent known to the notifying stockholder: (i) the name, age, business address and residence address of each proposed nominee and of the notifying stockholder; (ii) the principal occupation of each proposed nominee; (iii) a representation that the notifying stockholder is a holder of record of stock of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to nominate the person or persons specified in the notice; (iv) the class and total number of shares of capital stock and other securities of the Corporation that are owned beneficially and of record by the notifying stockholder and by the proposed nominee and, if such securities are not owned solely and directly by the notifying stockholder or the proposed nominee, the manner of beneficial ownership (beneficial ownership has the same meaning as provided in Regulation 13D under the Securities Exchange Act of 1934, as from time to time in effect (and any successor regulation) (the "Exchange Act")); (v) a description of all arrangements or understandings between the notifying stockholder or any of its affiliates or associates, and any others acting in concert with any of the foregoing, and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination or nominations are to be made by the notifying stockholder; (vi) such other information regarding such notifying stockholder and each nominee proposed by such stockholder as would be required to be included in a proxy statement filed with the Securities and Exchange Commission pursuant to Regulation 14A under the Exchange Act and the rules and regulations thereunder had the nominee been nominated, or intended to be nominated, by the Board; and (vii) the consent of each nominee to serve as a director of the Corporation if so elected. The Corporation may request any proposed nominee to furnish such other information as may reasonably be required by the Corporation to determine the qualifications of the proposed nominee to serve as a director of the Corporation. Within 15 days following the receipt by the Secretary of a stockholder notice of nomination pursuant hereto, the Corporate Governance and Nominating Committee shall instruct the Secretary of the Corporation to advise the notifying stockholder of any deficiencies in the notice as determined by the Board. The notifying stockholder shall cure such deficiencies within 15 days of receipt of such notice. No persons shall be eligible for election as a director of the Corporation unless nominated in accordance with the Bylaws. Nominations not made in accordance herewith may, in the discretion of the presiding officer at the meeting and with the advice of the Corporate Governance and Nominating Committee, be disregarded by the presiding officer and, upon his or her instructions, all votes cast for each such nominee may be disregarded. The determinations of the presiding officer at the meeting shall be conclusive and binding upon all stockholders of the Corporation for all purposes. So long as the Minimum Condition is satisfied, the provisions of this section shall not apply to the nomination by any holders of Class B Common Stock of any candidate for election as director; any such nominations shall be governed by clause (a) or (b) of Section 1.5 of these Bylaws. "Minimum Condition" means, at any time, the state of affairs where the total number of outstanding shares of Class B Common Stock is at least 10% of the total number of shares of the Class A Common Stock and Class B Common Stock outstanding.

1.5    Advance Notice of Other Matters to be Presented by Stockholders.    At any annual meeting or special meeting of stockholders, only such business as is properly brought before the meeting in accordance with this paragraph may be transacted. To be properly brought before any meeting, any proposed business must be either (a) specified in the notice of the meeting (or any supplement thereto) given by or at the direction of the Board or, so long as the Minimum Condition is satisfied, by holders of a majority of the voting power of all of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class, (b) otherwise properly brought before the meeting by or at the direction of the Board or, so long as the Minimum Condition is satisfied, by holders of a majority of the voting power of all of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class, or (c) if brought before the meeting by a stockholder other than holders of a majority of the voting power of all of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class, then (1) written notification of such proposed business (a "Stockholder Notification") must have been received by the Secretary of the Corporation from a stockholder of record on the record date for the determination of stockholders entitled to vote at such meeting not later than (i), with respect to business to be proposed at an annual meeting of stockholders, 120 days prior to the anniversary date of the immediately preceding annual meeting (provided, that if the date of the annual meeting is more than 30 days before or after the anniversary date of the immediately preceding annual meeting, the Stockholder Notification must have been received within 15 days after the public announcement by the Corporation of the date of the annual meeting) and (ii) with respect to business to be proposed at a special meeting of stockholders, the close of business on the 15th day following the date on which notice of such meeting is first given to stockholders or public disclosure of the meeting is made, whichever is earlier. Such Stockholder Notification shall set forth (A) a brief description of the business desired to be brought before the meeting, the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the bylaws of the Corporation, the language of the proposed amendment), the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf

the proposal is made; and (B) as to the stockholder giving notification, (i) the name and address of such stockholder and (ii) the class or series and total number of all shares of the Corporation that are owned beneficially and of record by such stockholder and, if such shares are not beneficially owned solely and directly by such stockholder, the beneficial owner(s) of such shares. Within 15 days following receipt by the Secretary of a Stockholder Notification pursuant hereto, the Corporation shall advise the stockholder of any deficiencies in the Stockholder Notification. The notifying stockholder may cure such deficiencies within 15 days after receipt of such advice, failing which the Stockholder Notification shall be deemed invalid.

1.6    Quorum for Stockholder Meetings.    At any meeting of the stockholders, the presence, in person or by proxy, of stockholders entitled to cast at least a majority of the votes which all stockholders are entitled to vote upon a matter shall constitute a quorum for the transaction of business upon such matter, and the stockholders present at a duly organized meeting can continue to do business until adjournment, notwithstanding the withdrawal of enough stockholders to leave less than a quorum. If a meeting cannot be organized because a quorum has not attended, those present may, except as otherwise provided by law, adjourn the meeting to such time and place as they may determine, but in the case of any meeting called for the election of directors, those who attend the second of such adjourned meetings, although less than a quorum, shall nevertheless constitute a quorum for the purpose of electing directors.

1.7    Voting.    Except as otherwise provided in the Corporation's Certificate of Incorporation (including in respect of the voting rights of shares of the Class B Common Stock), each stockholder of record shall have, at every stockholders' meeting, one vote for every share standing in his or her name on the books of the Corporation. "Certificate of Incorporation" means the Second Amended and Restated Certificate of Incorporation of the Corporation, as filed with the Secretary of State of the State of Delaware on November 16, 2006, of the Corporation, as it may from time to time be amended and in effect in accordance with law, and shall include any certificate of designations determining the designation, voting rights, preferences, limitations and special rights of any shares of the Corporation which have been adopted by the Board as permitted by the certificate of incorporation and the law, as then in effect.

1.8    Proxies.    Every stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy. A proxy may be submitted to the Secretary by a stockholder in writing, by telephone, electronically or any other means permitted by law.

1.9    Required Votes for Stockholder Action.    Except in respect of the election of directors (as to which a plurality of the votes of the shares entitled to vote on the election of a director and voted in favor thereof shall be required), all questions submitted to the stockholders and all actions by the stockholders shall be decided by the affirmative vote of the stockholders present, in person or by proxy, entitled to cast at least a majority of the votes which all stockholders present are entitled to vote on the matter, unless otherwise provided by the Certificate of Incorporation, the Bylaws or by law. For purposes of this section, in the event that a holder of shares of a class or series which are entitled to vote on a matter is present in person or by proxy at a meeting but is not permitted by reason of a legal disability or by a contractual restriction or otherwise to vote the shares such holder holds on such matter, the shares held by such holder and not so permitted to be voted shall nevertheless be considered entitled to vote and present for purposes of determining the number of votes required for stockholder action.

1.10    Ballots; Judges of Election.    Elections for directors need not be by ballot but the Board or the presiding officer at a meeting of stockholders may direct the use of ballots for voting at the meeting. In advance of any meeting of stockholders, the Board may appoint judges of election who need not be stockholders to act at such meeting or any adjournment thereof, and if such appointment is not made, the presiding officer of any such meeting may, and on request of any stockholder or his proxy shall, make such appointment at the meeting. The number of judges shall be one or three and, if appointed at a meeting on request of one or more stockholders or their proxies, the majority of the shares present and entitled to vote shall determine whether one or three judges are to be appointed. No person who is a candidate for office shall act as a judge. In case any person appointed as judge fails to appear or fails or refuses to act, the vacancy may be filled by appointment made by the Board in advance of the convening of the meeting or at the meeting by the person or officer presiding at the meeting. On request of the presiding officer of the meeting or of any stockholder or his proxy, the judges shall make a report in writing of any challenge or question or matter determined by them and execute a certificate of any fact found by them.

1.11    Action by Consent Without a Meeting.    To the fullest extent and in the manner permitted by law, any action required or permitted to be taken at a meeting of the stockholders or of a class or series of stockholders may be taken without a meeting of the stockholders or of such class or series of stockholders upon the consent in writing signed by such stockholders who would have been entitled to vote the minimum number of votes that would be necessary to authorize the action at a meeting at which all the stockholders entitled to vote thereon were present and voting. The consents shall be filed with the Secretary.

Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting at least 10 days prior to the meeting during ordinary business hours at the principal place of business of the Corporation. A list of stockholders entitled to vote at the meeting shall be produced and kept at the time and place of the meeting during the whole time thereof and may be examined by any stockholder who is present.

2.     BOARD OF DIRECTORS.

2.1    Authority of the Board of Directors.    Except as otherwise provided by law and subject to the provisions of the Certificate of Incorporation and the Bylaws, all powers vested by law in the Corporation may be exercised by or under the authority of, and the business and affairs of the Corporation shall be managed under the direction of, a Board that shall be constituted as provided by law, the Certificate of Incorporation and the Bylaws.

Except as otherwise provided by statute or these Bylaws, directors shall be elected at each annual meeting of stockholders by a plurality of votes cast and shall hold office until the next annual meeting of stockholders and until the election and qualification of their respective successors, subject to such director's earlier death or disability and subject to the provisions of Section 2.9 of these Bylaws. As used in these Bylaws, the term "entire Board" means the total number of directors which the Corporation would have if there were no vacancies on the Board.

(b)   Notwithstanding anything to the contrary herein, during the period that the Special Security Agreement (the "Security Agreement") by and between Onex Corporation ("Onex"), the Corporation and the Department of Defense ("DoD"), as amended from time to time, is in force, the Board shall be elected by the stockholders of the Corporation in accordance with the other provisions of these Bylaws and shall be composed of:

 (ii)  one or more representatives of Onex (the "Inside Directors"); and

(iii)  one or more cleared officers of the Corporation (the "Officer/Directors").

During the period that the Security Agreement is in force, the number of Inside Directors shall not exceed the combined total of Outside Directors and Officer/Directors. Except as specifically provided herein, each member of the Board, however characterized by this Section 2.2, shall have all of the rights, powers, and responsibilities conferred or imposed upon directors of the Corporation by applicable statutes and regulations, and by the Corporation's Certificate of Incorporation and these Bylaws. During the period that the Security Agreement is in force, the Chairman of the Board, as well as the Corporation's key management personnel,¹ must be resident citizens of the United States who have or who are eligible to possess DoD personnel security clearances at the level of the Corporation's facility security clearance. In addition, during the period that the Security Agreement is in force, the Chairman of the Board shall not be an Inside Director. All directors of the Corporation shall satisfy the pertinent requirements established in Section 2.2(c) of these Bylaws. During the period that the Security Agreement is in force, the Outside Directors may not be removed without prior notice to, and written notice stating no objection from, the Defense Security Service ("DSS"). During the period that the Security Agreement is in force, appointments of new or replacement Outside Directors must be approved by DSS.

¹

For purposes of these Bylaws, "key management personnel" shall have the meaning currently ascribed to it under paragraph 2-104 of the National Industrial Security Program Operating Manual ("NISPOM"): The senior management official and the Facility Security Officer must always be cleared to the level of the facility security clearance. Other officials, as determined by the DSS, must be granted a personnel security clearance or be excluded from access to classified information.

(b)   A majority of the Board, including at least one Inside Director and one Outside Director, shall be necessary to constitute a quorum.

(d)   Notwithstanding anything to the contrary herein, the Board shall not be authorized to take any of the actions specified in Section 2.4(d)(i) or 2.4(d)(ii) below unless it shall have received, with respect to each such action, the prior approval of holders of a majority of the voting power of the outstanding common stock of the Corporation:

2.5    Annual Organizational Meeting of the Board.    The Board shall hold an annual organizational meeting immediately following the annual meeting of the stockholders at the place thereof, without notice in addition to the notice of the annual meeting of stockholders, or at such other time as soon as practicable after such meeting as the Board shall determine and shall at the annual organizational meeting elect a Chief Executive Officer, a President, a Secretary and a treasurerTreasurer of the Corporation and such other officers of the Corporation as shall be provided by the Bylaws or determined by the Board to be appropriate, shall establish the standing committees of the Board provided by the Bylaws and may take such other action as the Board determines to be appropriate. Officers of the Corporation and standing and other committees of the Board may also be elected at any other time by the Board.

2.6    Other Meetings of the Board.    All meetings of the Board, other than the annual organizational meeting, shall be held at the principal office of the Corporation unless the Board (or the person or persons entitled to call and calling the meeting) shall decide otherwise, in which case such meetings may be held at such location within or without the State of Delaware as the Board (or the person or persons entitled to call and calling the meeting) may from time to time direct. Regular meetings of the Board shall be held at such time (and place) in accordance with such schedule as the Board shall have determined in advance and no further notice of regular meetings of the Board shall be required.

Non-Management Directors shall otherwise determine. The Independent Directors shall meet without any other director from time to time as they determine is appropriate. Special meetings of the Board may be called by the Chairman of the Board (if any), a Vice Chairman of the Board, (if any) the President or by any two or more directors by giving written notice at least two business days in advance of the day and hour of the meeting to each director (unless it is determined by the president or the Chairman of the Board (if any) to be necessary to meet earlier, in which case no less than 24 hours written notice shall be given), either personally or by facsimile, or other means including electronic means permitted by law. Attendance at any meeting of the Board shall be a waiver of notice thereof, unless such lack of notice is protested at the outset of the meeting. If all the members of the Board are present at any meeting, no notice of the meeting shall be required. "Independent Director" means a director who meets the criteria of independence established by the standards for the listing of the Class A Common Stock of the Corporation on the New York Stock Exchange and the Exchange Act and the rules and regulations promulgated thereunder, in order for such director to be treated as independent under such listing standards; provided, however, that, for purposes of Section 6.4 hereof, a director shall not be considered to be independent unless he or she, in addition to satisfying the foregoing requirements, has, directly or indirectly, no personal or financial interest, material to such director, in the transaction or category of transaction he or she is to review and vote on.

2.7    Board or Committee Action Without a Meeting.    Any action required or permitted to be taken by the Board or by any committee of the Board may be taken without a meeting if all of the members of the Board or of the committee consent in writing to the adoption of a resolution authorizing the action. The resolution and the written consents by the members of the Board or the committee shall be filed with the minutes of the proceeding of the Board or of the committee.

2.8    Participation in Board or Committee Meetings by Conference Telephone.    Any or all members of the Board or of any committee of the Board may participate in a meeting of the Board or a committee thereof by means of a conference telephone or other communications equipment allowing all persons participating in the meeting to hear each other at the same time. Participation by such means shall constitute presence in person at the meeting.

2.9    Resignation and Removal of Directors.    

(a)   Any director may resign at any time by delivering his resignation in writing to the President or Secretary of the Corporation, to take effect at the time specified in the resignation. The acceptance of a resignation, unless required by its terms, shall not be necessary to make it effective.

(b)   A director may only be removed by holders of a majority of the voting power of all of the outstanding Class A Common Stock and Class B Common Stock, voting together as a single class, which may remove any member of the Board for any reason permitted by the provisions of applicable state law or the Corporation's Certificate of Incorporation or these Bylaws.

(c)   If a director is removed in accordance with Section 2.9(b) of these Bylaws during the period that the Security Agreement is in force,

  (i)  the removal of an Outside Director shall not become effective until that director, the Corporation, and DSS have been notified, DSS provides written notification stating no objection, and a successor who is qualified to become an Outside Director within the terms of the Security Agreement has been nominated by the Corporation and approved by DSS;

 (ii)  notification to DSS of the removal of an Outside Director shall be the responsibility of the Secretary through the Facility Security Officer of the Corporation, and except as noted in Section 2.9(c)(iii) of these Bylaws, must be given at least twenty (20) days prior to the proposed removal date; and

(iii)  notwithstanding the foregoing, however, if immediate removal of any Outside Director is deemed necessary to prevent actual or possible violation of any statute or regulation, or actual or possible damage to the Corporation, the Outside Director may be removed at once, although DSS shall be notified prior to or concurrently with such removal.

(d)   Except as provided by this Section 2.9(d), the obligation of an Outside Director to abide by and enforce the Security Agreement shall terminate when the director leaves office, but nothing herein shall relieve the departing Outside Director of any responsibility that the director may have, pursuant to the laws and regulations of the United States, not to disclose classified or controlled unclassified information obtained during the course of the director's service on the Board, and such responsibility shall not terminate by virtue of the Outside Director leaving office. The Corporation's Facility Security Officer shall advise the departing Outside Director of such responsibility when the Outside Director leaves office, but the failure of the Corporation to so advise the Outside Director shall not relieve the Outside Director of any such responsibility.
