This Proxy Statement and the form of proxy are furnished to the shareholders of Astronics Corporation, a New York corporation (“Astronics” or the “Company”), in connection with the solicitation of proxies by the Board of Directors of the Company for use at the Annual Meeting of Shareholders (the “Annual Meeting”) to be held on Wednesday, May 8, 2024, at PECO, Inc., 11241 SE Highway 212, Clackamas, Oregon 97015 USA at 10:00 a.m. Pacific Time and at any adjournment thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders. In addition to solicitation by mail, to the extent necessary to ensure sufficient representation at the Annual Meeting, solicitations may be made by personal interview or telecommunication by officers and other regular employees of the Company. The cost of this proxy solicitation will be borne by the Company. It is contemplated that the Notice Regarding the Availability of Proxy Materials will be first sent to shareholders on or about March 26, 2024. The references to the Company’s website throughout this Proxy Statement are not, and should not, be deemed to be incorporated

by reference into this Proxy Statement or otherwise filed with the Securities and Exchange Commission. The Company’s principal executive offices are located at 130 Commerce Way, East Aurora, New York 14052.

If the proxy is properly executed and returned, and the shareholder specifies a choice on the proxy, the shares represented thereby will be voted (or withheld from voting) in accordance with the instructions contained therein.

If the proxy is executed and returned but no specification is made, the proxy will be voted (i) FOR the election of each of the nominees for director listed below, and (ii) FOR the proposal to ratify the appointment of the independent registered public accounting firm for the fiscal year ending December 31, 2024. The Board of Directors of the Company knows of no business that will be presented for consideration at the Annual Meeting other than the matters described in this Proxy Statement. If any other matters are properly presented at the Annual Meeting, the proxy holders will vote the proxies in accordance with their judgment.

In order for business to be conducted, a quorum must be present at the Annual Meeting. A quorum is a majority of the outstanding shares of Common Stock and Class B Stock combined entitled to vote at the Annual Meeting. Abstentions, broker non-votes and withheld votes will be counted in determining the existence of a quorum at the Annual Meeting. A broker non-vote occurs when a bank, broker or other nominee holding shares for a beneficial owner votes on some matters on the proxy card, but not on others, because the bank, broker or other nominee does not have instructions from the beneficial owner or discretionary authority (or declines to exercise discretionary authority) with respect to those other matters.

Directors will be elected by a plurality of the votes cast at the Annual Meeting, meaning the eight nominees receiving the most votes will be elected. Votes cast FOR the nominees will count as “yes votes,” WITHHOLD votes and broker non-votes are not considered votes cast for the foregoing purpose, and will have no effect on the outcome of the election of the Director nominees.

A majority of the votes cast is required to approve the selection of the Company’s auditors. Votes may be cast FOR, AGAINST or ABSTAIN on the approval of this proposal. Abstentions and broker non-votes are not counted in the number of votes cast and will have no effect on the results of the vote on this proposal.

Proxy cards that are executed and returned without any designated voting direction will be voted in the manner stated on the proxy card.

Brokers may not vote your shares on any non-routine matter in the absence of specific voting instructions from you. Please contact your broker directly if you have questions about how to provide such instructions. The execution of a proxy will not affect a shareholder’s right to attend the Annual Meeting and to vote in person. A shareholder who executes a proxy may revoke it at any time before it is exercised by giving written notice to the Secretary, by appearing at the Annual Meeting and so stating, or by submitting another duly executed proxy bearing a later date.

The Board of Directors has fixed the close of business on Tuesday, March 19, 2024 as the record date for determining the holders of Astronics Common Stock (“Common Stock”) and Astronics Class B Common Stock (“Class B Stock”) entitled to notice of and to vote at the Annual Meeting.

On March 19, 2024, Astronics Corporation had outstanding and entitled to vote at the Annual Meeting a total of 28,968,742 shares of Common Stock and 5,871,149 shares of Class B Common Stock.

Each outstanding share of Common Stock is entitled to one vote and each outstanding share of Class B Stock is entitled to 10 votes on all matters to be brought before the Annual Meeting. The Common Stock and Class B Stock vote as a single class on all matters presented at the Annual Meeting.

You can cast your vote:

Your presence at the Annual Meeting will not in itself revoke any proxy you may have given. If your shares are held in your own name (i.e., you are the shareholder of record), you may revoke your proxy at any time (to the extent it has not already been voted at the Annual Meeting), but a revocation will not be effective until it is received. Your proxy will be revoked (to the extent it has not already been voted at the Annual Meeting):

If your shares are held in street name through a broker, bank or other nominee for your benefit, you should contact that record holder to obtain instructions if you wish to revoke your vote before the Annual Meeting.

If you are a registered holder and your proxy is properly executed, returned and received before the Annual Meeting and is not revoked, it will be voted in accordance with your instructions. If you return your signed proxy but do not mark the boxes to show how you wish to vote on a proposal, the shares for which you have given your proxy will, in the absence of your instructions to the contrary, be voted as follows:

If your shares are held in street name through a broker, bank or other nominee for your benefit and your voting instruction form is properly executed, returned and received before the Annual Meeting and is not revoked, it will be voted in accordance with your instructions. If you have not furnished voting instructions within a specified period before the Annual Meeting, brokerage firms and other nominees may vote their customers’ unvoted shares on “routine” matters but not on non-routine matters. Routine matters include the ratification of the appointment of our independent registered public accounting firm, but do not include the other proposal on the ballot.

The voting instruction form also grants the proxy holders discretionary authority to vote on any other business that may properly come before the Annual Meeting as well as any procedural matters. As of the date of this proxy statement, the Company does not know of any other matters that will be presented at the Annual Meeting.

All shareholders of Astronics Corporation who owned shares of record on March 19, 2024 may attend the Annual Meeting. If you want to vote in person and you hold Common Stock or Class B Stock in street name (i.e., your shares are held in the name of a brokerage firm, bank or other nominee), you must obtain a proxy card issued in your name from your broker and

bring that proxy card to the Annual Meeting, together with valid identification. If you hold stock in street name and want to attend the Annual Meeting but not vote in person at the Annual Meeting, you must bring a legal proxy issued to you by your broker or nominee and valid identification.

Astronics is committed to minimizing the impact of its activities on the environment. The Company maintains a variety of formal policies and procedures related to protection of the environment, energy conservation and waste management, as well as general business practices that are part of its culture. These policies and procedures are specific to each subsidiary. In most instances, these policies and practices are embedded in Astronics’ Employee Handbook. Employees must certify - in many cases annually - that they have read and will comply with the Employee Handbook. In fact, Astronics’ PECO facility is a Zero Liquid Discharge facility.

In addition, when considering an acquisition or partnership, the Company embeds questions specific to environmental matters within its due diligence approach. These include claims, policies, certifications and procedures relative to environmental management. Astronics Corporation asks these in an effort to both promote positive environmental policies and practices as well as to minimize any risk when assessing the acquisition candidate.

While Astronics does not currently track environmental metrics on a company-wide basis, the Company recognizes the value and importance of reducing its impact on the global environment.

Astronics Connectivity Systems & Certification Corp. and Astronics Advanced Electronic Systems Corp. have processes that comply with the requirements of IS0-14001, the international standard for effective environmental management.

Most of the Company’s operations maintain formal programs that establish goals and measure progress towards those goals regarding reductions and disposal of hazardous substances, recycling and minimization of power consumption, among other efforts. In those operations that are not IS0-14001 compliant, Astronics meets or exceeds all applicable environmental laws and regulations by maintaining many initiatives and practices that reduce its impact on the

environment. Some examples of these initiatives and practices include policies to reduce paper, policies to reduce single occupancy commuting, replacement of older, less-efficient lighting with energy efficient motion-based LED lighting, active waste recycling, water consumption reduction programs, and providing electric car recharging stations and bicycle storage at its largest operation.

Each subsidiary is expected to conduct both government/regulatory mandated training as well as professional development training, depending upon that subsidiary’s areas of expertise. Specific certifications may be found at each subsidiary’s website: www.astronics.com/subsidiaries.

While Astronics Corporation does not have a separate vendor code of conduct, as part of its contracts, the Company Code of Conduct requires that its vendors adhere to the spirit of its Code of Ethics (see Social/Human Capital Management). In addition, language to this effect is often included in the Terms

and Conditions portion of the Company’s contracts with suppliers and customers. When required as part of an agreement, Astronics Corporation has signed a customer’s Code of Conduct.

Astronics strives to maintain the integrity of its supply chain to the best of its ability. Astronics Corporation files Form SD Conflict Minerals Disclosure to be compliant with the US Securities and Exchange Commission (“SEC”) regulations

and, in many instances, the Company also is required to comply with government standards in evaluating and choosing suppliers. Each subsidiary works with its suppliers to determine if legal and regulatory requirements are met.

Astronics complies with all applicable conflict minerals regulations, including the SEC’s Conflict Minerals Rule and the European Union’s Conflict Minerals Regulation.

Astronics’ Conflict Minerals Policy is to only use tin, tungsten, tantalum, or gold whose source can be traced to scrap/recycled materials or smelters and refiners that are conformant with the Responsible Minerals Initiative’s (RMI) Responsible Minerals Assurance Process (RMAP). Astronics encourages the use of responsibly mined minerals from the Democratic Republic of the Congo and adjoining countries.

To ensure compliance with this policy, Astronics has put in place procedures that conform with the Five-Step Framework

for Risk-Based Due Diligence as described in OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas.

Astronics’ standard purchase order terms and conditions require our suppliers to adapt a conflict minerals policy similar to Astronics and to provide Astronics each year with an updated Conflict Minerals Reporting Template (CMRT), the industry-standard reporting form published by the RMI.

A copy of Astronics’ current Form SD may be found on its website at www.astronics.com/about/conflict-minerals.

Astronics Corporation greatly values its employees and recognizes that, without them, the Company would not have achieved the success it has accomplished since inception. Astronics strives to provide a positive, supportive work culture with a clear global vision and a collaborative work style. The Company strongly believes that a focus on learning and supporting career development can lead to success. Astronics Corporation regularly earns “best employer” awards.

As it relates to customers, investors, suppliers and partners, the Company is dedicated to conducting business with integrity and responsibility for the greater good. Astronics Corporation promotes honest and ethical conduct, compliance with applicable government regulations and accountability by

all of its directors, officers and employees. When considering an acquisition or partnership, the Company embeds questions specific to human capital management within its due diligence approach. These questions are in the areas of culture, equal employment opportunity, compliance with governing bodies, ethics, as well as employee benefits. Astronics Corporation asks these in an effort to ensure that the acquisition candidate is a positive cultural fit and to minimize any risk when assessing the acquisition candidate.

Relative to collective bargaining agreements, the Company has hourly production employees at PECO who are subject to a collective bargaining agreement. Astronics Corporation considers its relations with all of its employees to be good.

Astronics Corporation’s Corporate Governance Guidelines outline expectations that the Board establish and promote policies that encourage a positive, supportive work culture.

The Board recognizes that culture is critical to the long-term success of Astronics and its strategy. Therefore, the policies referenced herein apply to the Board as well as to relationships among and between the Board and employees.

The lifeblood of any organization is its employee base. Astronics relies on its individual subsidiaries to regularly gather employee feedback, using the method each subsidiary believes is most appropriate. In some instances that feedback is obtained through “Town Hall” formats; in other instances

it is obtained through surveys. However the feedback is collected, the Company expects its managers to solicit and, where applicable, use employee feedback to improve its business practices and working environment.

Astronics believes that diversity and inclusion is critical for the attraction and retention of top talent. The Company employs policies and procedures to recruit women and minority talent as well as policies to ensure pay equality. Astronics Corporation has an Equal Employment Opportunity Policy whereby the Company commits to providing equal employment opportunity

for all qualified employees and applicants without regard to race, color, sex, sexual orientation, gender identity, religion, national origin, disability, veteran status, age, marital status, pregnancy, genetic information or other legally protected status. This policy is posted on the Astronics Corporation website at https://www.astronics.com/careers.

The Board of Directors has adopted a Code of Business Conduct and Ethics that is applicable to its Chief Executive Officer and Chief Financial Officer as well as all other directors, officers and employees of the Company. The Company will disclose any amendment to this Code of Business Conduct and Ethics or waiver from a provision of its Code of Business Conduct and Ethics that applies to the Company’s Chief Executive Officer, Chief Financial Officer or Principal Accounting Officer or Controller, including the name of such person to whom the waiver was granted, on its website.

Further, the Company has a policy on Combatting Human Trafficking to ensure that employees, agents and suppliers of the Company do not engage in human trafficking or human trafficking activities.

The Company’s explicit statement regarding not tolerating human trafficking can be found at https://investors.astronics.com/corporate­governance/governance-documents.

Each subsidiary is expected to conduct both government/regulatory mandated training as well as professional development training, depending upon that subsidiary’s areas of expertise. The Company requires all of its employees to certify that they have read and understood the Code of Ethics. Based upon the needs of, and regulations associated with, each of the Company’s businesses, Astronics Corporation requires training for both regulatory and corporate compliance purposes.

Astronics is committed to the safety of its customers and its employees. Each Astronics operation maintains environmental, health and safety policies that seek to promote the operation of its businesses in a manner that is protective of the health and safety of the public and its employees. Astronics Corporation’s operations offer several health and welfare programs to employees to promote fitness and wellness and

to encourage preventative healthcare. In addition, Astronics’ employees are offered a confidential employee assistance program that provides professional counseling to employees and their family members. Also, many of the Company’s operations offer greenspace for employees to use during their breaks.

It is Astronics’ intention to provide a safe, healthy working environment for its employees, to the extent possible. To achieve this, the Company has created the following policies,

all of which are available publicly, as indicated, some of which are internal to the organization:

Astronics offers a generous benefits program for its employees. The Company provides a drug-free work environment and

requires drug screening of all candidates accepting employment.

Astronics Corporation is proud to have received numerous awards, recognizing both product quality as well as the Company’s ability to provide an excellent work environment.

A few of these awards include: 6^th Best Large Company to Work For as part of Washington’s Best 100 Places to Work for 2023 by Seattle’s Business Magazine (included in 14 of last 17 years); 2023 Top Workplace Award-The Oregonian; 2023 Top Work Places Award-Orlando Sentinel; 2022 and 2023 Top Workplace Manufacturing (National); 2023 Top Workplace

Culture Excellence (National); 2021 America by Design: People’s Choice Award; 2020 Crain’s List: Chicago’s Largest Research and Development Labs; 2019 GOOD DESIGN Award; APEX 2019 Best Cabin Innovation Award; General Atomics Supplier Excellence Award (2016, 2017, 2018); Tech Briefs 2017 Product of the Year; Chicago’s 101 Best and Brightest Companies to Work For (2021 and 2022); Intel Supplier Continuous Quality Improvement; 2017 and 2018 Military & Aerospace Electronics Innovators Awards-Platinum; 2018 Global Technology Award; and 2014-2022 Top Workplace Award-Orange County Register.

Customer feedback is critically important to advancing initiatives and improving service levels. To accomplish this, the Company actively seeks customer feedback on an ongoing basis, relying upon each subsidiary to engage as that business

sees fit. Customer feedback mechanisms employed by Astronics subsidiaries routinely include the use of customer “scorecards” as well as soliciting input through ongoing discussions.

Astronics’ employees participate in numerous community engagement activities. Astronics supports and encourages its employees to be active and participate in local charitable activities and believes that the employee should choose to support the organization which means the most to her/him/them. The Company supports its employees at the

subsidiary level, providing them with needed time off and, at times with matching donations, to engage with the charities of their choice. Those charities have included supporting local food banks and Marine Corps Toys for Tots.

Information security is critical to the Company’s operations around the world. We seek to employ industry-leading security practices, while leveraging software and product security engineering to protect our networks, systems and information from cyber threats. Our cybersecurity strategy prioritizes detection, analysis and response to known, anticipated or unexpected cyber threats, effective management of cyber risks, and resilience against cyber incidents. We continuously strive to exceed industry best practices and implement risk-based controls to protect our partners’ and the Company’s information and information systems. In order to protect both commercial and defense-related businesses and support our production operations, the Company has adopted security principles in accordance with the National Institute of Standards and Technology Cybersecurity Framework, contractual requirements and other global standards. The Company conducts regular periodic training of its employees as to the protection of sensitive information which includes

security awareness training intended to prevent the success of “phishing” attacks. We also leverage industry and government associations, third-party benchmarking, audits, and threat intelligence feeds, among other things, to ensure the effectiveness of our cybersecurity efforts and proactively allocate resources.

The Company’s Director of Information Technology provides a report to the Board of Directors on an annual basis, or more frequently as needed, with respect to information security activity, security assessments, controls and investments.

The Company has in place a Cyber Risk Liability Insurance policy written by the Traveler’s for a twelve-month term expiring July 1, 2024. The twelve-month premium was $74,088. The policy has a limit of $3 million in the aggregate and provides coverage related to data breaches and other cyber security measures.

Astronics Corporation is dedicated to conducting business with integrity and responsibility. The Company promotes honest and ethical conduct, compliance with applicable government regulations and accountability by all of its directors, officers and employees. The Company’s Board has adopted Corporate Governance Guidelines and a Code of Business Conduct and Ethics which, in conjunction with Board committee charters, form the framework for its governance and is applicable to its directors and all employees. The Board regularly reviews corporate governance developments and modifies its Corporate Governance Guidelines, committee charters and key policies as warranted. The Company will disclose on its website any amendment to its Code of Business Conduct and Ethics or waiver from a provision of this Code of Business Conduct and Ethics that applies to the Company’s Chief Executive Officer, Chief

Financial Officer or Principal Accounting Officer or Controller, including the name of such person to whom the waiver is granted. Astronics Corporation’s business is conducted by its employees, managers and officers, under the direction of the Chief Executive Officer (CEO) and the oversight of the Board, to enhance the long-term value of Astronics Corporation for its shareholders. The Board of Directors stands in a fiduciary relation to the Company and, in discharging these fiduciary duties, directors shall act in a manner that they reasonably believe to be in the best long-term interests of the Company, in particular, the interests of the shareholders. The Board recognizes that the interests of the Company and its shareholders are advanced when they take into account the concerns of and the effect of any action upon employees, suppliers, customers, the communities in which operations are established, and other pertinent factors.

Astronics has several policies and charters to guide the conduct and action of the Company’s employees and Board of Directors. Some of the Company’s policies contain sensitive

information and are not made public, such as our policies on Social Media and Cybersecurity. Website links for those that are available to the public follow as indicated:

Astronics Corporation’s By-Laws, as amended, provide that the Board of Directors shall be composed of not less than three nor more than nine persons, as determined by the Board of Directors. Currently, the Board includes eight members, elected at each annual meeting of shareholders and who serve for a term of one year or until their successors are duly elected and qualified.

Unless instructions to the contrary are received, it is intended that the shares represented by proxies will be voted for the election as Directors of Robert T. Brady, Jeffry D. Frisby,

Peter J. Gundermann, Warren C. Johnson, Robert S. Keane, Neil Y. Kim, Mark Moran and Linda G. O’Brien, each of whom has been previously elected by Astronics Corporation shareholders. If any of these nominees should become unavailable for election for any reason, it is intended that the shares represented by the proxies solicited herewith will be voted for such other person as the Board of Directors shall designate. The Board of Directors has no reason to believe that any of these nominees will be unable or unwilling to serve if elected to office.

Pursuant to the Nasdaq listing standards, a majority of the Directors are required to be independent, as that term is defined by applicable laws and regulations and in the Nasdaq listing standards. A Director will be considered independent only if the Board has affirmatively determined that the Director has no material relationship with Astronics, either directly or as a partner, shareholder or officer of an organization that has a relationship with Astronics that, based on the requirements of applicable laws and regulations and the Nasdaq listing standard, would impair his or her independent judgment. Under the terms of the Company’s Corporate Governance Guidelines, not more than three individuals who fail to be determined to be independent Directors shall serve on the Board at any one time, provided, however, that this limitation on the number of non-independent directors shall not require a Director to resign or retire from the Board prior to the expiration of a term to which he or she was duly elected by the shareholders so long as the Board then has a majority of independent Directors.

The Board annually reviews all commercial and charitable relationships of Directors to determine if there is a material relationship that would preclude the Board from making an affirmative determination that an individual Director is independent. To facilitate this review, each non-employee Director annually provides information regarding that Director’s business and other relationships with Astronics, its affiliates and senior management to enable the Board to evaluate the Director’s independence.

The Board of Directors has determined that each of its current directors, except for Mr. Gundermann, is independent within the meaning of the Nasdaq Stock Market, LLC director independence standards as currently in effect. In addition, each member of the Audit Committee, the Compensation Committee, the Nominating/Governance Committee and the Sustainability Committee is independent.

Directors shall possess the highest personal and professional ethics and integrity, and, in performance of their duties as directors, shall represent the long-term interests of the shareholders. The Board believes that its membership should reflect a diversity of experience, gender, race and ethnicity. Directors are selected on the basis of experience and personal capacities, including experience in industries similar to Astronics Corporation’s, managerial or other leadership experience; business acumen or particular expertise, business development experience, strategic capability, independence of judgment; familiarity with corporate governance, risk assessment and the responsibilities of directors; standing and reputation as a person of integrity; the potential contribution of each individual to the diversity of backgrounds, experience

and competencies which the Nominating/Governance Committee desires to have represented and ability to work constructively with the CEO and the Board.

Directors must devote sufficient time to carrying out their duties and responsibilities effectively and should be committed to serving on the Board for an extended period of time. Directors are expected to inform the Chairman if there is any significant change in their personal circumstances, including a change in their principal job responsibilities. Directors are expected to attend meetings of the Board and Committees of the Board on which they serve, except for good reason, and be prepared.

The Board of Directors and its committees meet regularly throughout the year and also hold special meetings and act by written consent from time to time as appropriate. All directors are expected to attend each meeting of the Board of Directors and the committees on which she/he/they serves, and are also invited, but not required, to attend the Annual Meeting. During

the year ended December 31, 2023, the Board of Directors held five meetings. Each director attended at least 75% of the total number of meetings of the Board of Directors and the committees on which she/he/they serve held in 2023. All directors attended the 2023 Annual Meeting.

The Audit Committee consists of Messrs. Brady (Chair), Frisby and Kim, each of whom is independent within the meaning of the Nasdaq Stock Market, LLC director independence standards as currently in effect. The Board of Directors has determined that Messrs. Brady and Frisby qualify as an “audit committee financial expert” as defined under federal securities laws serving on its Audit Committee. Information regarding the functions performed by the Audit

Committee is set forth in the “Report of the Audit Committee” included in this Proxy Statement. The Audit Committee held eight meetings in 2023.

The Audit Committee is governed by a written charter approved by the Board of Directors that is posted on the “Corporate Governance” section of the Company’s website at https://investors.astronics.com/corporate-governance.

The Compensation Committee consists of Messrs. Kim (Chair), Keane and Moran, and Ms. O’Brien, each of whom is independent within the meaning of the Nasdaq Stock Market, LLC director independence standards as currently in effect. The Compensation Committee is responsible for reviewing and approving compensation levels for the Company’s executive officers and reviewing and making recommendations to the Board of Directors with respect to other matters relating to the compensation practices of the Company. In appropriate circumstances, the Compensation Committee considers the recommendations of the Company’s Chief Executive Officer with respect to reviewing and approving compensation levels for other executive officers.

The Compensation Committee does not use outside compensation consultants on a regular basis. The Compensation Committee may consult broad-based, third-party survey data to obtain a general understanding of current compensation practices of companies of similar size and industry in which the Company competes for employees.

The Compensation Committee held five meetings in 2023.

The Compensation Committee is governed by a written charter approved by the Board of Directors that is posted on the “Corporate Governance” section of the Company’s website at https://investors.astronics.com/corporate-governance.

The Nominating/Governance Committee consists of Messrs. Moran (Chair), Keane and Johnson and Ms. O’Brien, each of whom is independent within the meaning of the Nasdaq Stock Market, LLC director independence standards as currently in effect. The Nominating/Governance Committee is responsible for evaluating and selecting candidates for the Board of Directors and addressing and overseeing corporate governance matters on behalf of the Board of Directors.

In performing its duties to recommend nominees for the Board of Directors, the Nominating/Governance Committee seeks director candidates with the following qualifications, at minimum: high character and integrity; substantial life or work experience that is of particular relevance to the Company; sufficient time available to devote to his or her duties; and ability and willingness to represent the interests of all shareholders rather than any special interest group. The Nominating/Governance Committee may use third-party search firms to identify Board of Director candidates. It also relies upon recommendations from a wide variety of its contacts, including current executive officers, directors, community leaders and shareholders, as a source for potential candidates.

Shareholders wishing to submit or nominate candidates for election to the Board of Directors must supply information in writing regarding the candidate to the Nominating/Governance Committee at the Company’s executive offices in East Aurora, New York. This information should include the candidate’s name, biographical data and qualifications. Generally, the Nominating/Governance Committee will conduct a process of making a preliminary assessment of each proposed nominee based upon biographical data and qualifications. This information is evaluated against the criteria described above and the specific needs of the Company at the time. Additional information regarding proposed nominees may be requested. On the basis of the information gathered in this process, the Nominating/Governance Committee determines which nominees to recommend to the Board of Directors. The Nominating/Governance Committee uses the same process for evaluating all nominees, regardless of the source of the recommendation.

The Nominating/Governance Committee held four meetings in 2023. The Nominating/Governance Committee is governed by a written charter that is posted on the “Corporate Governance” section of the Company’s website at https://investors.astronics.com/corporate-governance.

In February 2022, the Board of Directors established a Sustainability Committee. The Sustainability Committee consists of Messrs. Frisby (Chair), Brady and Johnson. The Sustainability Committee held two meetings in 2023.

The Sustainability Committee assists the Board in its assessment and evaluation of the Company’s sustainability programs and initiatives pertaining to the Company’s business, operations and employees. The Sustainability Committee

monitors and evaluates the Company’s approach to sustainability and assists in the integration of sustainability planning into the Company’s business planning and strategy.

The Sustainability Committee is governed by a written charter that is posted on the “Corporate Governance” section of the Company’s website at https://investors.astronics.com/corporate-governance.

Independent directors meet regularly in executive sessions. Non-management directors are all those directors who are not Company employees and includes directors, if any, who are not independent as determined by the Board of Directors. The Company’s non-management directors consist of all of its current directors except Mr. Gundermann. An executive

session of the Company’s non-management directors is generally held in conjunction with each regularly scheduled Board of Directors meeting. Additional executive sessions may be called at the request of the Board of Directors, the Lead Independent Director or the non-management directors.

In addition to the Chairman, the Board has a Lead Independent Director. Mr. Brady has served in this role since February 2020. The principal role of the Lead Independent Director is to serve as liaison between the Chairman and CEO and the Directors. The specific responsibilities of the Lead Independent Director are, among others, to:

(i) collaborate with the Chairman and CEO to ensure the appropriate flow of information to the Board;

(ii) consult with the Chairman and CEO regarding Board agenda items;

(iii) coordinate and develop the agenda for and preside at executive sessions and sessions of the Board’s independent Directors, and as appropriate, communicate to the Chairman and CEO on the substance of the discussions;

(iv) in the absence of the Chairman, act as Chair of meetings of the Board;

(v) recommend, when necessary, special meetings of the Board; and

(vi) act as principal liaison between the Directors and the Chairman and CEO on sensitive issues.

The agenda for each Board meeting shall be established by the Chairman and the Lead Independent Director, and any Director may request items to be included on the agenda. Ample time is scheduled for each Board meeting to assure full discussion of important matters whether included on the agenda or not. Agendas always include financial and operating reports in addition to other reports, such as business unit and subject matter presentations, that could enhance a Director’s perspective and knowledge on various matters. Agenda and meeting materials are distributed in advance of Board and Committee meetings, and each Director has a duty to review the materials prior to the meeting.

The Board is committed to continuous improvement and employs a rigorous process to ensure that the composition of the Board is diverse, balanced and aligned with the evolving needs of the Company. The Board assesses the diversity of the directors’ experience, expertise, perspective, tenure and age, among other attributes, to ensure it has an appropriate mix of skills and experience to fulfill its oversight obligations.

The Board also considers the Company’s long-term strategy when evaluating which specific skills and experience are required

and weighs those skills when evaluating the current and potential directors. As part of the evaluation of the directors’ skills and experience, the Board reviews a director skillset chart which identifies expertise, experience and other characteristics that contribute to an effective and well­ functioning board. The skills and qualifications for each current Director may be found within their biographies on pages 13 to 16.

The Board and each of the committees performs annual self-evaluations. The Nominating/Governance Committee develops and conducts the Board evaluation and ensures that

each committee of the Board conducts its own self-evaluation. The Board of Directors then reviews this feedback and makes improvements, as necessary.

Directors who also serve as CEOs or in equivalent positions should not serve on more than two boards of public companies in addition to the Astronics Board, and other Directors should not serve on more than four other boards of public companies in addition to the Astronics Board. Membership on additional public company boards beyond the limits specified above by a director for exceptional reasons requires approval by the Nominating/Governance Committee or its chairperson. Directors are expected to notify the Nominating/Governance

Committee in writing before accepting election or appointment to any public company board on which they did not serve when appointed to the Astronics Board.

The Board does not believe that arbitrary term limits on Directors’ service are appropriate nor does it believe that Directors should expect to be renominated annually. The Board self-evaluation process described above is an important determinant for Board tenure.

Although the Company does not have a formal policy regarding communications with the Board of Directors, shareholders may communicate with the Board of Directors by writing to: Board of Directors, Astronics Corporation, 130 Commerce Way, East Aurora, New York 14052. Shareholders who would like their submission directed to a particular

director may so specify and the communication will be forwarded, as appropriate. The Board believes that management should speak for the Company. Accordingly, each Director may refer all inquiries from shareholders, analysts, the press or customers to the CEO.

A shareholder entitled to vote in the election of Directors, may nominate a candidate for the Board of Directors only if written notice of the shareholder’s intent to do so has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Company and received by the Company (a) with respect to an election to be held at an Annual Meeting of shareholders, not later than sixty (60) nor more than ninety (90) days prior to the first anniversary of the preceding year’s Annual

Meeting (or, if the date of the Annual Meeting is changed by more than twenty (20) days from such anniversary date, within ten (10) days after the date the Company mails or otherwise give notice of the date of such Annual Meeting), and (b) with respect to an election to be held at a special meeting of shareholders called for that purpose, not later than the close of business on the tenth (10th) day following the date on which notice of the special meeting was first mailed to the shareholders of the Company.

Each shareholder’s notice of intent to make a nomination shall set forth: (i) the name(s) and address(es) of the shareholder who intends to make the nomination and of the person or persons to be nominated; (ii) a representation that the shareholder (a) is a holder of record of stock of the Company entitled to vote at such Annual Meeting, (b) will continue to hold such stock through the date on which the Annual Meeting is held, and (c) intends to appear in person or by proxy at the Annual Meeting to nominate the person or persons specified in the notice; (iii) a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nomination is to be made by the shareholder; (iv) such other information regarding each nominee proposed by such shareholder as would be

required to be included in a proxy statement filed pursuant to Regulation 14A promulgated under Section 14 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as now in effect or hereafter modified, had the nominee been nominated by the Board of Directors; and (v) consent of each nominee to serve as a director of the Company if so elected. The Company may require any proposed nominee to furnish such other information as may reasonably be required by the Company to determine the qualifications of such person to serve as a director. No person shall be eligible for election as a director unless nominated (i) by a shareholder in accordance with the foregoing procedure or (ii) by the Board of Directors or a committee designated by the Board of Directors.

The Board of Directors oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance shareholder value. A fundamental part of risk management is to understand the specific risks the Company faces and what mitigating steps are being taken, while balancing what is an appropriate level of risk for the Company. The involvement of the full Board of Directors in setting and overseeing 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. On a regular basis, senior leaders are invited to present to the Board of Directors on each business. These presentations include opportunities as well as risks and mitigating actions. On an ongoing basis, the Company relies on its business leaders to identify and mitigate risks wherever possible.

While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board also have oversight responsibility for specific areas of risk management. In particular, the Audit Committee focuses on financial risk, including internal controls over financial reporting, as well as compliance 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. The Sustainability Committee oversees the Company’s sustainability programs and assists in the integration of sustainability planning into the Company’s risk management process. The Company maintains a Cybersecurity policy as well as complaint procedures for accounting and auditing matters, the latter of which may be found on the Corporate Governance section of the Company’s website.

At present, the Board has determined that combining the roles of the Chief Executive Officer and Chairman is in the best interests of the Company. In addition to the Chairman, the Board has a Lead Independent Director who has substantial and significant responsibility on Board matters. The Board is free to reconsider the combination of Chief Executive Officer and Chairman roles in the future and may decide to do so if conditions change. It is the sense of the Board that a size of 7 to 9 members is about right for the Company in light of its size and complexity of its business. The Board proposes a slate of nominees to the

shareholders for election to the Board. Shareholders may also propose nominees for consideration by the Nominating/Governance Committee by submitting the names and supporting information according to the deadlines set forth in the Company’s proxy statement for its most recent Annual Meeting to: Secretary, Astronics Corporation, 130 Commerce Way, East Aurora, New York 14052. Between annual shareholder meetings, the Board may elect Directors to fill vacancies to serve until the next Annual Meeting.

Among its duties, the Board plans for the succession of the CEO. To assist the Board, the CEO provides an annual succession planning summary to the Board and advises the Board of his recommendations and evaluations of potential successors. The

Compensation Committee provides assessment and feedback by the Board of Directors to the CEO on the strategic leadership, development, and internal and external representation of the Company.

The Board believes that the primary and most constructive interaction with management is through the normal process of scheduled Board and Committee meetings, whether they be on regular business or special matters, at which any discussions can best be informed by the collective and varied knowledge and experience of Directors and management. The Board also recognizes, however, that matters of integrity and corporate conduct, were they to arise, may call for direct access to senior

management. As is judicious under these circumstances, independent Directors are free to contact executive officers and other senior managers of the Company without senior corporate management present. As noted above in the Board Oversight of Risk discussion, senior leaders are invited on a regular basis to present to the Board of Directors on each business. In this manner, the Board becomes familiar with leadership beyond the office of the CEO and CFO.

The Company has in place Directors’ and Officers’ Liability Insurance policies written by the Chubb Group, Zurich, Travelers, C.N.A., AIG and AXA XL, for a twelve-month term expiring July 1, 2024. The twelve-month premium was $737,505. The

policies have limits of $55 million in the aggregate and provide indemnification benefits and the payment of expenses in actions instituted against any director or officer of the Company for claimed liability arising out of their conduct in such capacities.

The Nominating/Governance Committee is responsible for developing the general criteria, subject to approval of the Board of Directors, for use in identifying, evaluating and selecting qualified candidates for election or re-election to the Board. The Nominating/Governance Committee periodically reviews the appropriate skills and characteristics required of the Board members in the context of the current composition of the Board. The Nominating/Governance Committee, in recommending candidates to the Board, seeks to create a Board that is strong in its collective knowledge and has a diversity of skills and experience with respect to accounting and finance, management and leadership, vision and strategy, business operations, business judgment, industry knowledge, corporate governance and global markets. When the Nominating/Governance Committee reviews a potential new candidate, it looks specifically at the candidate’s qualifications in light of the needs of the Board and the Company at that time, given the attributes of the existing Directors. In identifying candidates for director, the Board of

Directors takes into account:

The Board of Directors believes that ethnic and gender diversity are important considerations when evaluating Director candidates along with such factors as background, skills, experience and expertise. Ms. O’Brien is diverse with respect to gender and Mr. Kim is diverse with respect to race/ethnicity. The Company will continue to consider all of these factors when proposing future candidates for the Board.

In determining whether to renominate the current slate of Directors, the Board of Directors focused primarily on the information discussed in each of the directors’ individual biographies set forth elsewhere in this Proxy Statement. In particular, with regard to Ms. O’Brien and Messrs. Brady, Frisby, Johnson and Moran, the Board of Directors considered their significant experience, expertise and background with regard to the aerospace industry. With regard to Messrs. Kim

and Keane, the Board of Directors considered their technical knowledge, significant mergers and acquisition experience, and expertise with complex, multinational organizations. The Board of Directors also considered the more than thirty years of experience with the Company represented by Mr. Gundermann, the Company’s Chairman of the Board and Chief Executive Officer.

No interlocking relationship exists between any member of the Compensation Committee or any of the Company’s executive officers and any member of any other company’s board of directors or compensation committee (or equivalent).

No member of the Compensation Committee was, during 2023 or prior thereto, an officer or employee of the Company

or any of its subsidiaries, except that from 1988 to 1994, Mr. Keane was an executive at Flex-Key Corporation, a former subsidiary of Astronics Corporation.

The Board believes that, in order to align the interests of the Directors and shareholders, Directors should have a significant financial stake in the Company. The Corporate Governance Guidelines adopted by the Board in December 2019, as amended on February 26, 2021, provide that within four years of joining the Board or within four years of adoption of the Guidelines, whichever is later, each non-employee Director is expected to accumulate and maintain ownership of at least the number of shares equal to 400% of the annual cash retainer

for the applicable calendar year, divided by the average of the closing price of a share of Astronics Corporation Common Stock for the previous calendar year. Outstanding equity awards are not included in the calculation of stock ownership for purposes of the calculation under the Corporate Governance Guidelines. Each non-employee Director was in compliance with the director stock ownership requirements in the Corporate Governance Guidelines as of December 31, 2023.

The Company’s Amended and Restated 2017 Long Term Incentive Plan authorizes it to grant stock options, stock appreciation rights, restricted stock, restricted stock units (“RSUs”) and stock bonuses to non-employee directors of the Company. The Compensation Committee has authority to grant awards under the Amended and Restated 2017 Long Term Incentive Plan. The Nominating/Governance Committee makes recommendations to the Compensation Committee as to equity grants for directors and awards are granted by the Board. The Nominating/Governance Committee reviews and approves equity awards to directors based upon a review of competitive compensation data, its assessment of individual performance and retention considerations. Awards to non­employee directors of stock options, stock appreciation rights and restricted stock units may not vest sooner than six months from the date of grant, except in certain circumstances such as death, disability or retirement. Recipients of RSUs may not sell or otherwise dispose of the shares issued upon settlement of RSUs until six months following the date of issuance of such shares.

On February 23, 2023, Ms. O’Brien and each of Messrs. Boushie, Brady, Frisby, Johnson, Keane, Kim and Moran were awarded 7,438 RSUs. Each RSU represents the right to receive, at settlement, one share of Common Stock. The RSUs issued to Ms. O’Brien and each of Messrs. Brady, Frisby, Johnson, Keane, Kim and Moran vested in full six months from the grant date on August 23, 2023, on which date Ms. O’Brien and each of Messrs. Brady, Frisby, Johnson, Keane, Kim and Moran were issued 7,438 shares of Common Stock. The RSUs issued to Mr. Boushie vested on May 23, 2023 upon his exit from the Board, and, on May 25, 2023, Mr. Boushie was issued 7,438 shares of Common Stock. Shares issued in settlement of RSUs are subject to a minimum holding period of six months following the date of issuance.

As of March 12, 2024, the non-employee directors as a class hold 1.2% of the outstanding Common Stock and 14.1% of the outstanding Class B Stock of the Company. We believe this aligns the Board’s interests with shareholder interests. See “Security Ownership of Certain Beneficial Owners and Management” on page 49.

The Audit Committee, with the approval of the Board of Directors, has selected Ernst & Young LLP as the independent registered public accounting firm, to act as auditors of Astronics Corporation for 2024. All services provided on the Company’s behalf by Ernst & Young LLP during 2023 and 2022 were approved in advance by the Audit Committee.

While the Audit Committee is responsible for the appointment, compensation, retention, termination and oversight of our independent registered public accounting firm, the Board of Directors believes, as a matter of good governance, that it is advisable to give shareholders an opportunity to ratify this

selection. If this proposal is not approved by our shareholders at the Annual Meeting, the Audit Committee may reconsider its selection of Ernst & Young LLP. Even if the selection is ratified by our shareholders, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and our shareholders.

Representatives of Ernst & Young LLP are expected to attend the Annual Meeting and will have the opportunity to make a statement if they desire and will be available to respond to appropriate questions.

The Audit Committee has adopted a policy that requires advance approval of all audit, audit-related, tax services, and other services performed by the independent registered public accounting firm. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee

must approve the permitted service before the independent registered public accounting firm is engaged to perform it. The Audit Committee may delegate to an Audit Committee member the authority to approve permitted services provided that the delegated member reports any decisions to the Committee at its next scheduled meeting.

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors. Management has primary responsibility for the financial statements and the reporting process including the systems of internal controls. In fulfilling its oversight responsibilities, the Audit Committee reviewed the audited financial statements in the Annual Report with management and the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements.

The Audit Committee is comprised of the directors named below, each of whom is independent as defined under Section 10A(m)(3) of the Exchange Act, and under the Nasdaq Stock Market, LLC listing standards currently in effect. In addition, pursuant to the requirements of Section 407 of the Sarbanes-Oxley Act of 2002, the Board of Directors has determined that it has more than one “audit committee financial expert” as defined under federal securities laws serving on its Audit Committee.

The Audit Committee operates under a written charter which includes provisions requiring that the Audit Committee approve in advance all audit and non-audit services to be provided by independent public accountants.

The Audit Committee reviewed and discussed with management and Ernst & Young LLP, the Company’s independent registered public accounting firm, the Company’s audited consolidated financial statements for the year ended December 31, 2023. In addition, the Audit Committee discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission.

The Audit Committee has received the written disclosures and the letter from the independent accountant required by the applicable requirements of the PCAOB regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with the independent accountant the independent accountant’s independence.

Based on the Audit Committee’s review and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on

Form 10-K, for the year ended December 31, 2023, for filing with the Securities and Exchange Commission.

In accordance with and to the extent permitted by applicable law or regulation, the information contained in the Report of Audit Committee of Astronics Corporation shall not be incorporated by reference into any future filing under the

Securities Act of 1933, as amended, or the Exchange Act and shall not be deemed to be “soliciting material” or to be “filed” with the Securities and Exchange Commission under the Securities Act of 1933, as amended, or the Exchange Act.

The Company’s named executive officers are: Peter J. Gundermann, Chairman, President and Chief Executive Officer of the Company; David C. Burney, Executive Vice President­ Finance, Chief Financial Officer and Treasurer of the Company; James S. Kramer, Executive Vice President of the Company and President of Luminescent Systems, Inc. and Astronics DME LLC; Michael C. Kuehn, Executive Vice President of the Company and President of Astronics Connectivity Systems & Certification Corp. and Astronics AeroSat Corporation; James F. Mulato, Executive Vice President of the Company and President of Astronics Test Systems, Inc.; and Mark A. Peabody, Executive Vice President of the Company and President of the Aerospace Segment of the Company (collectively, the “Named Executive Officers”).

The Company’s compensation philosophy and program objectives are directed by two primary guiding principles. First, the program is intended to provide levels of compensation sufficient to attract, motivate and retain talented executives. Second, the program is intended to create an alignment of interests between the Company’s executives and shareholders such that a portion of each executive’s compensation is directly linked to maximizing long-term growth of shareholder value.

The Company’s goals are to outperform its industry, in terms of growth, financial performance, and innovation. In support of these goals, the executive compensation program is designed to energize its executive officers to outperform its industry and to reward performance that is directly relevant to the Company’s short-term and long-term success. As such, the

Company provides both short-term and long-term incentives. The Compensation Committee has structured the executive compensation program with three primary underlying components: base salary, annual bonus and long-term incentives. The Company’s compensation objective is to (i) compensate its executive officers at a base level that is competitive with salaries near the average salaries paid by companies of similar size and nature, (ii) provide the opportunity for its executive officers to earn additional compensation in the form of annual bonuses, and (iii) design long-term incentive plans to focus executive efforts on the long-term goals of the Company and to maximize total return to the Company’s shareholders, while taking into account the Company’s performance and strategic goals.

The Compensation Committee utilizes its expertise and knowledge of the markets in which the Company competes for employees in determining compensation policy. In addition, the Compensation Committee may consult broad-based, third-party survey data to obtain a general understanding of current compensation practices of companies of similar size and industry.

The Company does not have a policy regarding the ability of employees or directors to purchase financial instruments (including prepaid forward variable contracts, equity swaps, collars, and exchange funds) or to otherwise hedge or pledge Company stock, and as such these types of hedging transactions are generally permitted.

The Compensation Committee approves the salaries paid to the Company’s executive officers and, as part of its responsibilities, reviews these salaries annually. Individual salary changes are based on a combination of factors such as the performance of the executive, salary level relative to the

competitive market, level of responsibility, growth of Company operations and experience of the executive. In appropriate circumstances, the Compensation Committee considers the recommendations of the Company’s Chief Executive Officer for the executive officers other than himself.

The Compensation Committee has the authority to award discretionary annual incentive bonuses to the Company’s executive officers. Annual incentive bonuses are intended to compensate officers for achieving financial, strategic and operational success. Bonuses are not tied to specific, objective targets such as achieving a particular profit level. The Compensation Committee considers a number of factors in determining bonuses. Factors considered include profitability, sales growth over the most recent two- or three-year period, the performance of the individual in the view of the Compensation Committee, comparisons to

external broad-based compensation of similar size and industry and available information with respect to the aerospace and defense industry. Bonuses are not capped. Bonuses are reviewed and approved by the Compensation Committee. In appropriate circumstances, the Compensation Committee considers the recommendations of the Company’s Chief Executive Officer for executive officers other than himself. In 2020 and 2021, annual bonuses were suspended as the Company recovered from the impact of the COVID-19 pandemic on the Company. In 2022, no annual bonuses were paid due to the financial performance of

the Company as the Company and the aerospace industry continued to recover from the impact of the COVID-19 pandemic. For 2023, bonus amounts were determined based on the average annual sales growth over the most recent three-year period. For 2023, the Board of Directors determined to pay out the bonus earned in shares of Common Stock, rather than cash, in the form

of stock bonuses to Named Executive Officers and key employees. The shares underlying the stock bonuses were issued to Named Executive Officers on March 1, 2024 in the amounts indicated in the section entitled “Grants of Plan-Based Awards” on page 40 below.

The Company believes that long-term performance is achieved through an ownership culture that incentivizes its executive officers through the use of stock-based awards. The Company’s 2017 Long Term Incentive Plan, as Amended and Restated in May 2021 (the “LTIP”) was established to provide certain of the Company’s employees, including its executive officers, with incentives to help align those employees’ interests with

the long-term interests of the Company’s shareholders. The Compensation Committee believes that the use of stock-based awards is an important element of achieving its compensation goals. The Company’s broad-based Employee Stock Purchase Plan, its prior stock option plans, and the LTIP have provided the principal methods for its executive officers to acquire equity or equity-linked interests in the Company.

In May 2017, the 2017 Long Term Incentive Plan was approved by shareholders, providing for the grant of 1,757,040 shares of stock-based awards. This amount included 757,040 shares previously available for issuance under the 2005 Director Stock Option Plan and the 2011 Stock Option Plan, plus an additional 1,000,000 shares. In May 2021, the Amended and Restated 2017 Long Term Incentive Plan was approved by shareholders, providing for an increase in the

number of shares of stock with respect to which awards may be issued under the LTIP from 1,757,040 to 3,144,774. The LTIP provides a flexible framework that permits the development and implementation of a variety of stock-based incentives which enables the Company to base awards on key performance metrics as well as to further align its long-term incentive compensation with peers and shareholder interests.

The LTIP authorizes the Company to grant options to purchase shares of Common Stock to its employees. Prior to approval of the LTIP, the Company issued options to executive officers and key employees under its 2011 Stock Option Plan. No new issuances will be made under the 2011 Stock Option Plan. The goal of stock options is to create long-term incentives for key employees to maximize future performance of the Company. The Compensation Committee is the administrator of the LTIP. Stock option grants generally are made annually or at the commencement of employment. Stock options awarded to employees that vest solely on the basis of time may not vest more quickly than ratably over three years from the date of grant, except in certain circumstances such as death, disability, retirement, termination of employment due to workforce reduction or job elimination, change in control or in connection with the establishment of terms and conditions of employment necessary for recruitment or as a result of a business combination or acquisition. Recipients may not dispose of any shares acquired pursuant to an exercise of stock options until a date which is at least two years from the date of grant of the stock option and at least one year after the date of exercise of the stock option. The Compensation Committee reviews and approves equity awards to executive officers based upon a review of competitive compensation data, its expectation of future individual

performance, a review of each executive’s existing long-term incentives and retention considerations. Periodic stock option grants are made at the discretion of the Compensation Committee to eligible employees and, in appropriate circumstances, the Compensation Committee considers the recommendations of the Company’s Chief Executive Officer for executives other than himself.

The Compensation Committee’s practice has generally been to award options at its December meeting, except that no options were awarded in 2020 as the Compensation Committee’s meeting was delayed until January 2021.

In December 2023, the Named Executive Officers were awarded stock options under the LTIP in the amounts indicated in the section entitled “Grants of Plan-Based Awards” on page 40 below. Stock options granted by the Company have an exercise price equal to the fair market value of the Common Stock on the day of grant and generally expire 10 years after the date of grant. The stock options awarded in December 2023 straight-line vest 33-1/3% per annum based on continued employment. Option award agreements provide for a holding period for shares acquired upon exercise of two years from the date of grant and at least one year after the date of exercise.

In 2023, the Company issued performance-based restricted stock units (“RSUs”) to Named Executive Officers and time-based restricted stock units to key employees. RSUs awarded to employees that vest solely on the basis of passage of time may not vest more quickly than ratably over three years from the date of grant, except in certain circumstances such as death, disability, retirement, termination of employment due to workforce reduction or job elimination, change in control or in connection with the establishment of terms and conditions of employment necessary for recruitment or as a result of a business combination or acquisition. Recipients of RSUs may not sell or otherwise dispose of the shares issued upon settlement of RSUs until six months following the date of issuance of such shares. The Compensation Committee’s practice has been to award RSUs at its February meeting when the audit for the prior fiscal year is typically substantially complete.

In February 2023, the Company issued performance-based RSUs to Messrs. Gundermann, Burney, Kramer, Peabody, Mulato and Kuehn in the amounts indicated in the section entitled “Grants of Plan-Based Awards” on page 40 below. The performance criteria for issuance of such awards is based on the Company’s average annual Adjusted EBITDA for the period of January 1, 2023 through December 31, 2025. Adjusted EBITDA is defined as the Company’s earnings before interest, taxes, depreciation, and amortization, adjusted

by the Compensation Committee in its sole discretion for any extraordinary, unusual or nonrecurring events, including, but not limited to insurance proceeds, legal settlements, impairments or unique investments in research and development projects.

For purposes of determining the vesting of the performance­ based RSUs issued in 2023, the target number of RSUs will be earned if the Company’s mathematical average annual Adjusted EBITDA for the performance period of January 1, 2023 to December 31, 2025 is less than 15%, but at least equal to 10%, of the Company’s mathematical average annual revenue for the performance period. If the average annual Adjusted EBITDA is less than 10% of the average annual revenue for the performance period, 75% of the target number of RSUs will be earned. If the average annual Adjusted EBITDA is greater than or equal to 15% of the average annual revenue for the performance period, 115% of the target number of RSUs will be earned.

For the RSUs awarded to Messrs. Gundermann, Burney, Kramer, Peabody, Mulato and Kuehn in February 2021, the average annual Adjusted EBITDA was less than 10% of the average annual revenue for the performance period of January 1, 2021 to December 31, 2023. As such, 75% of the target number of RSUs was earned.

For 2023, the Board of Directors determined to pay out the annual bonus earned in shares of Common Stock, rather than cash, in the form of stock bonuses to Named Executive Officers and key employees. The shares underlying the stock

bonuses were issued to Named Executive Officers on March 1, 2024 in the amounts indicated in the section entitled “Grants of Plan-Based Awards” on page 40 below.

While the Company does not presently have stock ownership guidelines for executive officers, the Named Executive Officers as a class hold as of March 12, 2024, 3.5% of the outstanding Common Stock and 26.2% of the outstanding Class B Stock of the Company. The Company believes this aligns

management’s interests with shareholder interests. See “Security Ownership of Certain Beneficial Owners and Management” on page 49 below. As described on page 24, the Company does require ownership by each member of the Board of Directors.

The Company has entered into an Employment Termination Benefits Agreement with each of Messrs. Gundermann, Burney, Kramer and Peabody, as described on page 45 below. In addition, as described in the “Pension Benefits” section beginning on page 43 below, Mr. Gundermann is a participant

in the SERP, while Messrs. Burney, Kramer and Peabody are each participants in the SERP II. The Company has not entered into an Employment Termination Benefits Agreement with Mr. Kuehn or Mr. Mulato. Neither Messrs. Kuehn nor Mulato are participants in the SERP or SERP II.

Effective December 1, 2023, the Board of Directors adopted a Policy for the Recovery of Erroneously Awarded Compensation, commonly known as a “clawback” policy. This policy was adopted to comply with Section 10D of the Exchange Act and the Nasdaq listing standards adopted in 2023 as mandated by the Dodd-Frank Act. Under the policy, which applies to the Company’s current and certain former Section 16 officers, the Company must recover erroneously awarded incentive-based compensation on a pre-tax basis, subject to very limited exceptions. Recovery is triggered by accounting restatements that correct errors that are material to

previously issued financial statements (“Big R” restatements), as well as restatements that correct errors that are not material to previously issued financial statements but would result in a material misstatement if (a) the errors were left uncorrected in the current report or (b) the error correction was recognized in the current period (“little r” restatements). The policy does not provide for enforcement discretion by the Compensation Committee or the Board and requires recovery regardless of whether a covered person engaged in any misconduct or is at fault.

The Company provides its shareholders with the opportunity to cast an advisory vote every three years on its executive compensation program (referred to as a “say-on-pay proposal”). At the Company’s Annual Meeting of Shareholders held on May 23, 2023, approximately 91% of the votes cast on the say-on-pay proposal at that Annual Meeting were voted in favor of the proposal. The Compensation Committee

believes that this result affirms shareholders’ support of the Company’s approach to executive compensation, and therefore maintained this approach for 2024. The Compensation Committee will continue to consider the outcome of the Company’s say-on-pay votes when making future compensation decisions for named executive officers.

The Compensation Committee of the Board of Directors (the “Committee”) determines the compensation of the Chief Executive Officer and other executive officers of the Company. The Committee is composed entirely of directors who are neither executive officers nor employees of the Company. In addition to determining the salary and bonus compensation for the Company’s executive officers, the Committee determines the grants under the Company’s Amended and Restated 2017 Long Term Incentive Plan and oversees the administration of other compensation plans and programs.

The Committee has reviewed the Compensation Discussion and Analysis contained in this proxy statement and has discussed it with management. In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Directors that the Compensation Discussion and Analysis be included in this proxy statement for filing with the Securities and Exchange Commission.

In reviewing executive compensation, it is important to distinguish the reported compensation provided to Named Executive Officers from the compensation that was actually awarded to Named Executive Officers. The Company has provided the following additional compensation table in order to remove the volatility related to the effects of changes in actuarial assumptions on the value of the Named Executive Officers’ pension benefits as required to be disclosed in the

Summary Compensation Table. This table is not a substitute for the Summary Compensation Table, which appears on page 33.

The table below shows the total compensation required to be reported in the Summary Compensation Table, but excluding any change in pension value.

The following table sets forth the cash compensation as well as certain other compensation earned by the Company’s Named Executive Officers during the years ended December 31, 2023, 2022 and 2021. Such amounts do not reflect actual cash received by the Named Executive Officers in 2023, 2022 or 2021.

Amounts reflected under the “Change in Pension Value and Non-Qualified Deferred Compensation Earnings” are primarily the result of a decrease from the prior year in the discount rate applied to calculate the present value of such benefits. No payments were made and no changes were made under the SERP or SERP II.

In accordance with the final rule issued under Section 953(b) of the Dodd-Frank Act, companies, including Astronics Corporation, are required to disclose the ratio of the total annual compensation of their CEO to that of their median employee. The SEC rules require disclosure of (i) the median of the annual total compensation of all employees of Astronics Corporation, except the CEO, (ii) the annual total compensation of the CEO, and (iii) the ratio of the amount of the CEO to the amount of the median employee’s annual total compensation of all employees of Astronics Corporation. Because the SEC rules do not mandate a particular approach to determining the median employee, Astronics Corporation has employed the following approach:

Astronics Corporation elected to identify its median employee as of December 31, 2023. The median employee was identified by calculating the total cash compensation granted in 2023 to all employees, excluding the CEO, employed as of

December 31, 2023. The fixed compensation of employees hired during the year or acquired through acquisition was annualized. The ratio disclosed below was calculated using the annual total compensation of Mr. Gundermann and of the median employee for 2023.

As calculated using the methodology required for the Summary Compensation Table, the total annual compensation of Mr. Gundermann was $2,650,211 and the total annual compensation of the median employee was $63,982. This yields a ratio of 41.42 to 1. If the ratio were calculated based upon “awarded” pay rather than “reported” as described on page 32, the total annual compensation of Mr. Gundermann would have been $2,041,064 and the total annual compensation of the median employee would remain as $63,982.
