PROXY STATEMENT FOR ANNUAL MEETING

OF SHAREHOLDERS TO BE HELD MAY 17, 2018

QUESTIONS & ANSWERS

PROXY STATEMENT

What is a Proxy and a Proxy Statement?

The Company’s Board of Directors is soliciting proxies for the 2018 Annual Meeting of Shareholders. A proxy is your authorization for someone else to vote on your behalf in the way you want to vote and allows you to be represented at the Annual Meeting of Shareholders even if you are unable to attend. A Proxy Statement is the document the United States Securities and Exchange Commission requires and the Company provides to explain the matters you are being asked to vote on by proxy and to disclose certain relevant information.

On or about April 3, 2018, the Company mailed to shareholders of record as of March 19, 2018 (other than those who previously requested electronic delivery), a Notice of Internet Availability of Proxy Materials (the "Notice") containing instructions on how to access the Proxy Statement and Annual Report for the year ended December 31, 2017. If you received a Notice by mail, you will not receive a printed copy of the proxy materials in the mail. The Notice instructs you on how to electronically access and review all the proxy materials, and these materials are available at https://www.proxyvote.com or https://materials.proxyvote.com/371901. The Notice also includes instructions about how you may request to receive proxy materials in printed form on a one-time or on-going basis.

What will I be voting on?

• Election of seven directors (see pages 11 - 13).

• Ratification of the appointment of Ernst & Young LLP as the Company’s auditors for the fiscal year ending December 31, 2018 (see page 37).

• Approval, on an advisory basis, of the compensation of the Company's named executive officers (see page 38).

The Board of Directors recommends a vote: FOR each of the nominees to the Board of Directors; FOR ratification of the appointment of Ernst & Young LLP as the Company’s auditors for the fiscal year ending December 31, 2018; and FOR approval, on an advisory basis, of the compensation of the Company's named executive officers.

How do I vote?

You can vote either in person at the Annual Meeting or by Proxy without attending the Annual Meeting. We urge you to vote by Proxy even if you plan to attend the Annual Meeting so that we will know as soon as possible that enough votes will be present for us to hold and conduct business at the meeting. If you attend the meeting and wish to vote in person, you must withdraw your earlier-dated Proxy in accordance with this Proxy Statement and provide proof of ownership of Company shares as of the record date of March 19, 2018.

Please note that there are separate telephone and Internet arrangements, depending upon whether you are a holder of record (that is, if your shares are registered in your own name with the Company's transfer agent and you have possession of your stock certificate(s)) or whether you hold your shares in "street name" (that is, if your shares are held for you by a broker or other nominee).

Shareholders of record voting by Proxy may use one of the following three options:

• Vote by Internet (log on to https://www.proxyvote.com and follow the directions there);

• Vote by toll-free telephone (1-800-690-6903 - instructions are on the Proxy Card or Voting Instruction Form); or

• Fill out the enclosed Proxy Card or Voting Instruction Form, sign it, and mail it.

If you hold your shares in "street name," please refer to the information forwarded by your broker or other nominee to see which options are available to you.

A beneficial owner who wants to cast a vote directly, rather than have a broker or other nominee do so, can either: become a registered owner; or ask the broker or nominee to execute a proxy on your behalf. You can become a registered owner by having your broker or other nominee "certificate" your position, in which case you will receive an actual certificate for your stock, or your share ownership can be moved into a "direct registration system." Alternatively, you can check a box on the Voting Instruction Form indicating your plan to attend the meeting and to vote your shares directly, in which case your broker or other nominee should then send you your proxy. Please contact your broker or other nominee for more details.

The telephone and Internet voting facilities for shareholders of record will close at 11:59 p.m. EDT on May 16, 2018. The telephone and Internet voting procedures are designed to authenticate shareholders by the use of control numbers and to allow you to confirm that instructions have been properly recorded.

Can I change my vote?

Yes. At any time before your Proxy is voted at the meeting, you may change your vote by:

• Revoking it by written notice to the Corporate Secretary at the address on the cover of the Proxy Statement;

• Delivering a later-dated Proxy (including a telephone or Internet vote);

• Voting by telephone or Internet at a subsequent time; or

6

• Voting in person at the meeting.

If you hold your shares in "street name," please refer to the information forwarded by your broker or other nominee for procedures on revoking or changing your Proxy.

How many votes do I have?

You will have one vote for every share of common stock that you owned on March 19, 2018.

How many shares are entitled to vote?

There were 273,608,967 shares of the Company common stock outstanding as of March 19, 2018, and entitled to vote at the meeting. Each share is entitled to one vote.

How many votes must be present to hold the meeting?

Under the Company’s Bylaws, a majority of all of the voting shares of the capital stock issued and outstanding as of March 19, 2018, must be present in person or by Proxy to hold the Annual Meeting.

What if I do not vote for some or all the matters listed on my Proxy Card or Voting Instruction Form?

If you return a Proxy Card or Voting Instruction Form without indicating your vote for some or all of the matters, if permissible, your shares will be voted as follows for any matter you did not vote on:

• For the approval of the director nominees to the Board of Directors listed on the card.

• For ratification of Ernst & Young LLP as the Company’s auditors for the fiscal year ending December31, 2018.

• For the approval, on an advisory basis, of the compensation of the Company's named executive officers.

How many votes are needed for the approval of items upon which the shareholders are being asked to vote?

• Under Michigan law, the seven nominees for director will be elected by a plurality of the votes cast. Notwithstanding the foregoing, the Company's Bylaws provide that if a director is elected by less than a majority of the votes cast, then such director shall promptly tender his or her resignation by written notice to the Board of Directors.

• Ratification of Ernst & Young LLP as the Company's auditors for the fiscal year ending December 31, 2018, is by a majority of votes cast.

• The proposals to approve the compensation of the Company's named executive officers is advisory and the Board of Directors will take such votes into account when considering future actions.

7

What if I vote to "abstain?"

A vote to "abstain" on the election of the directors or on ratification of Ernst & Young LLP as the Company's auditors will have no effect on the outcome. A vote to abstain with respect to approval of named executive officer compensation will be taken into account by the Board of Directors in determining future action.

What if I do not return my Proxy Card or Voting Instruction Form and do not attend the Annual Meeting?

If you are a holder of record and you do not vote your shares, your shares will not be voted.

If you hold your shares in "street name," and you do not give your broker or other nominee specific voting instructions for your shares, your broker or other nominee may not be permitted to exercise voting discretion with respect to certain matters to be acted upon.

If you do not give your record holder specific voting instructions and your record holder does not vote on the matters to be voted upon, the votes will be "broker non-votes." "Broker non-votes" will have no effect on the vote for the election of directors or the other matters to be voted upon as set forth in this Proxy Statement.

Is my vote confidential?

Proxy instructions, ballots, and voting tabulations that identify individual shareholders are handled in a manner that protects your individual voting privacy. Your individual vote will not be disclosed either within the Company or to third parties, except:

• as necessary to meet applicable legal requirements;

• to allow for the tabulation of votes and certification of the vote; or

• to facilitate successful Proxy solicitation by our Board of Directors.

Occasionally, shareholders provide written comments on their Proxy Cards or Voting Instruction Forms which are then forwarded to the Company’s management.

How can I receive a copy of the Company’s Form 10-K?

You can obtain, free of charge, a copy of our Form 10-K for the year ended December 31, 2017, which we recently filed with the Securities and Exchange Commission, by writing to:

Each shareholder as of the record date, as an owner of the Company, is entitled to vote on matters to come before the Annual Meeting. The use of Proxies allows a shareholder of the Company to be represented at the Annual Meeting if the shareholder is unable to attend in person.

There are four ways to vote your shares:

1) By Internet at https://www.proxyvote.com We encourage you to vote this way.

2) By toll-free telephone (1-800-690-6903)

3) By completing and mailing your Proxy Card or Voting Instruction Form

4) By written ballot at the Annual Meeting

If the form of Proxy accompanying this Proxy Statement is properly executed using any of the methods described above, the shares represented by the Proxy will be voted at the Annual Meeting of Shareholders and at any adjournment of the meeting. Where shareholders specify a choice, the Proxy will be voted as specified. If no choice is specified, the shares represented by Proxy will be voted FOR the election of all nominees named in the Proxy; FOR ratification of Ernst & Young LLP as the Company’s auditors for the fiscal year ending December 31, 2018; and FOR approval, on an advisory basis, of the compensation of the Company's named executive officers. These proposals are described in this Proxy Statement. A Proxy may be revoked prior to its exercise by (1) delivering a written notice of revocation to the Corporate Secretary, (2) delivery of a later-dated Proxy, including a telephone or Internet vote, or (3) attending the meeting and voting in person, as discussed above.

VOTING SECURITIES AND RECORD DATE

March 19, 2018, has been fixed by the Board of Directors as the record date for determining shareholders entitled to vote at the Annual Meeting. On that date, 273,608,967 shares of the Company’s common stock, par value $.06 per share, were issued and outstanding. Shareholders are entitled to one vote for each share of the Company’s common stock registered in their names at the close of business on the record date. Abstentions and broker non-votes are counted for the purposes of determining the presence or absence of a quorum for the transaction of business. Abstentions and broker non-votes are not, however, counted in tabulations of votes cast on matters presented to shareholders, though the Board will consider abstentions in determining future actions.

ELECTION OF DIRECTORS

The Company’s Restated Articles of Incorporation specify that the Board of Directors shall consist of at least six, but not more than nine members, with the exact number to be determined by the Board. The Board has currently set the number of directors at seven. The Restated Articles of Incorporation state that directors shall be elected annually for terms expiring at the next annual meeting of shareholders.

All of the members of the Company’s Board of Directors qualify as "independent directors" as determined in accordance with the current listing standards of The NASDAQ Global Select Market ("NASDAQ"). Based on these current NASDAQ listing standards, the Company’s Board has identified and affirmatively determined the following directors have no material relationships with the Company other than as a director and are independent: Leslie Brown, Gary Goode, Jim Hollars, John Mulder, Richard Schaum, Fred Sotok, and James Wallace. In making its independence determinations, the Board considered: the former employment and a former consulting arrangement of Mr. Mulder; the former employment of Mr. Hollars; and the fact that Mr. Sotok's son had an interest in a small vendor of the Company. The Board determined that these circumstances do not interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Each of the current Board of Directors members have been determined to meet the required experience and qualifications set forth in the Company's Position Profile: Member of the Board of Directors, including, among them, high levels of personal and professional integrity, distinguished management careers, and the demonstrated ability to work effectively as Board members. Combined with the other desirable characteristics and experience of such individuals, these individuals have the experience, qualifications, attributes, and/or skills (which are described below) which led the Nominating and Corporate Governance Committee to recommend such individuals to the Board for nomination for election to the Board, and led the Board to conclude such individuals should be nominated for election to the Board.

The terms of all current Board of Directors members will expire upon the election of the directors to be elected at the 2018 Annual Meeting. The Board has (upon the recommendation of the Company's Nominating and Corporate Governance Committee), re-nominated Leslie Brown, Gary Goode, James Hollars, John Mulder, Richard Schaum, Fred Sotok, and James Wallace for election as directors at the Annual Meeting, each to serve a one-year term expiring in 2019. The Nominating Committee and Corporate Governance Committee continues to avail itself of a variety of resources in its efforts to identify qualified and diverse candidates. Candidates are sought not only in traditional corporate environments, but also other environments such as government, academia, private enterprise, nonprofit organizations, and a variety of professions. In order to promote diversity, the Nominating and Corporate Governance Committee is: willing to consider exceptions to the Board of Directors Attendance and Overboarding Policy for diverse candidates; considering search firms with a track record of identifying qualified, diverse director candidates; as appropriate, seeking to engage with organizations representing the interests of women and minorities; and periodically reviewing its processes and procedures to ensure there are no structural impediments to increasing Board diversity. The Board is building a pool of diverse candidates and believes Board diversity will increase sooner rather than later.

Unless otherwise specifically directed by a shareholder’s marking on the Proxy Card or Voting Instruction Form, or in directions given either via the Internet or telephone, the persons named as Proxy voters in the accompanying Proxy will vote for the nominees described above and below. If any of these nominees becomes unavailable, which is not now anticipated, the Board may designate a substitute nominee, under the recommendation of the Nominating and Corporate Governance Committee, in which case the accompanying Proxy will be voted for the substituted nominee. Proxies cannot be voted for a greater number of persons than the number of nominees named.

A plurality of votes cast by shareholders at the meeting is required to elect directors of the Company under Michigan law. Accordingly, the nominees who receive the largest number of affirmative votes will be elected, regardless of the number of votes received. Notwithstanding the foregoing, the Company, in response to a shareholder proposal and with the proponent's concurrence with the Company's implementation of the same, amended its Bylaws to provide that if a director is elected by less than a majority of the votes cast, then such director shall promptly tender his or her resignation by written notice to the Board of Directors. Each of the nominees has agreed to tender his or her resignation in writing to the Board if he or she is not elected by a majority of votes cast. Broker non-votes and votes withheld will not have a bearing on the outcome of the election (though the Nominating and Corporate Governance Committee and Board

11

will consider abstentions in making future nominations). Votes will be counted by Inspectors of Election appointed by the presiding officer at the Annual Meeting.

The Board of Directors recommends a vote FOR the election of all persons nominated by the Board.

The content of the following table relating to age and business experience is based upon information furnished to the Company by the nominees and directors, as of February 15, 2018.

CORPORATE GOVERNANCE

The Company operates within a comprehensive plan of corporate governance set forth in the Gentex Corporation Corporate Guidelines (*) as adopted for the purpose of defining responsibilities, setting high standards of professionalism and personal conduct, and assuring compliance with such responsibilities and standards. The Company regularly monitors developments in the area of corporate governance.

The Board of Directors has an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee, and, in accordance with the Company's Bylaws, may appoint other committees from time to time. Each standing committee has a written charter. All such charters, as well as any documents marked with an asterisk (*) in this Proxy Statement, are available under the heading "Corporate Governance" on the Company’s web site at http://ir.gentex.com. A hard copy of any of these documents will be provided to any shareholder who submits a request in writing to the Corporate Secretary, Gentex Corporation, 600 North Centennial Street, Zeeland, MI 49464.

Each member of the Board of Directors is expected to abide by the Gentex Corporation Board of Directors Attendance and Overboarding Policy (*), including the expectation to attend all meetings of the Board, all applicable committee meetings, and each annual meeting of shareholders. All then members of the Board attended the 2017 Annual Meeting of Shareholders. Each of the current members of the Board, including all nominees for the Board, is expected to attend the 2018 Annual Meeting of Shareholders. During 2017, the Board held five Board meetings. All directors attended at least 75 percent of the aggregate number of meetings of the Board and Board committees on which they served.

Responsiveness to Shareholders

• The fact that the Company has declassified its Board of Directors and implemented majority voting for directors (in the form of a director resignation Bylaw) in response to shareholder proposals, as well as allowing its shareholder rights plan (poison pill) to expire, demonstrates responsiveness to expressed shareholder concerns. In fact, implementation of majority voting for directors (in the form of a director resignation Bylaw) was done with the input and concurrence of the shareholder proponent as to form of adoption of the same.

• The Company also implemented a Lead Independent Director Policy (*) to address concerns raised by shareholders when the Company had a non-independent Chair of the Board, again demonstrating its commitment to good corporate governance and ongoing engagement with shareholders.

• The Company has added a Sustainability section to its website, annually publishes a sustainability report and additional diversity considerations to its director nominating policies in response to suggestions from shareholders. Such diversity considerations, along with the actual practices of the Nominating and Corporate Governance Committee, have led to a broader and more diverse director candidate pool.

• The Company's on-going efforts concerning diversity have led to increasing diversity through all levels of the organization.

Board of Directors Leadership Structure

• Fred Bauer served as Chair of the Board of Directors and Chief Executive Officer (CEO) of the Company for 40 plus years prior to his retirement as of December 31, 2017.

• Though the Company is fortunate to continue to have access to Mr. Bauer's wealth of experience as Chairman Emeritus, Founder, and Advisor, in connection with his retirement, James Wallace was elected Chair of the Board.

• While Mr. Bauer served as Chair of the Board and CEO, the Board implemented a Lead Independent Director Policy (*) and the independent members of the Board had as an agenda item, in connection with each Board meeting, the opportunity to meet (and have met on other occasions as well).

• The Company acknowledges that independent board leadership is important, and the independent directors will continue to meet outside of the presence of management.

• Even with an independent Chair of the Board, the Company continues to believe it is important that the Board have flexibility to determine the most qualified person to serve as Board Chair rather than unduly impairing such flexibility with any policy requiring an independent Board Chair.

15

• The Board now has an independent Chair alleviating the need for a Lead Independent Director (though the Lead Independent Policy, as amended, remains in place to continue to provide the Board such flexibility).

Audit Committee

• The Company’s Audit Committee currently includes Messrs. Goode (Chair), Schaum, and Sotok.

• The Audit Committee met five times during the fiscal year ended December 31, 2017. Information regarding the functions performed by the Committee is set forth in the following "Report of the Audit Committee."

• The Audit Committee has adopted a policy titled "Complaint Submission and Handling Policy", to enable confidential and anonymous reports or complaints generally as well as those relating to auditing and accounting matters to the Audit Committee specifically. 

• The Audit Committee reviews and approves all related-party transactions in accordance with its Charter. This review and approval covers all manners of related-party transactions, which are viewed in light of applicable disclosure requirements, independence standards for directors, and applicable Company codes and policies.

Compensation Committee

• The Company’s Compensation Committee currently includes Messrs. Goode (Chair), Schaum, and Wallace.

• The Compensation Committee met eleven times during the fiscal year ended December 31, 2017. The Compensation Committee is responsible for administering all of the Company’s incentive plans and other compensation arrangements for executive officers of the Company.

In the last year, consistent with the Compensation Committee Charter, and with the consent of the Compensation Committee, the Company retained an independent compensation consultant, Mercer (US) Inc. ("Mercer") to advise on certain compensation matters. Mercer's engagement included an: assessment of the Company's existing compensation program; a competitive analysis of a peer-group of publicly-traded organizations, including base salaries, annual incentives, and long-term incentives, plan design alternatives; pay trends; performance metrics; stock ownership guidelines; and employment agreements. The assessment also included recommendations for reporting on the same, including certain

16

recommendations for potential changes to executive and director compensation. The Compensation Committee did consider the independence of Mercer in assessing the information and recommendations provided by Mercer. Mercer provided peer group and industry compensation data to both management and the Compensation Committee for executives and directors. Such data was used by the Compensation Committee as a frame of reference for adjusting the Company's compensation structure as more fully described herein, including establishing executive compensation targets for base pay, short-term non-equity incentives, as well as consideration of potential long-term equity incentives.

• The Board of Directors, based on the recommendation of the Compensation Committee, has also adopted an "Anti-Hedging and Anti-Pledging Policy" (*) and "Clawback Policy" (*).

• The Compensation Committee does not believe that the Company's compensation policies and practices are reasonably likely to have a material adverse effect on the Company.

Nominating and Corporate Governance Committee

• The Company’s Nominating and Corporate Governance Committee currently includes Messrs. Wallace (Chair) and Goode and Ms. Brown, although such committee regularly receives input from other directors.

• The Nominating and Corporate Governance Committee met formally one time during the fiscal year ended December 31, 2017 (but met informally and held other discussions at regularly scheduled Board of Directors meetings, and otherwise, including consideration of potential candidates for nomination to the Board).

The Nominating and Corporate Governance Committee then conducts interviews and reviews, as appropriate and necessary. The Nominating and Corporate Governance Committee then meets to consider and approve the most qualified candidates so it can make its recommendation to the full Board of Directors.

• The Nominating and Corporate Governance Committee has established the minimum qualifications for candidates, which are contained in a document called "Position Profile: Member of the Board of Directors" (*). Those required qualifications include: working and/or experience with an entrepreneurial company; high level of personal and professional integrity; successful and distinguished business management career (using the Company's core principles); understanding of the Company's markets; and ability to work effectively with current Board members.

The Audit Committee and the Compensation Committee, respectively, report to the Board periodically with respect to such topics. This oversight does not necessarily have any material effect on the Company's leadership structure. The Board also annually reviews the Company’s various insurance coverages.

19

Report of the Audit Committee

The primary purpose of the Audit Committee is to assist the Board of Directors in fulfilling its oversight responsibilities for management’s conduct of the Company’s accounting and financial reporting processes and the Company’s system of internal controls regarding finance, accounting, legal compliance and ethics. The Audit Committee’s function is more fully described in its Charter, which the Board has adopted and is available on the Company's website. The Audit Committee reviews this Charter on an annual basis. The Board annually reviews the NASDAQ listing standards’ definition of independence for audit committee members and has determined that each member of the Audit Committee meets that standard.

Management is responsible for the preparation, presentation, and integrity of the Company’s financial statements, and financial reporting principles, internal controls and procedures designed to ensure compliance with accounting standards, applicable laws and regulations. The Company’s independent auditors, Ernst & Young LLP, are responsible for performing an independent audit of the consolidated financial statements and expressing an opinion on the conformity of those financial statements with generally accepted accounting principles.

Pursuant to a meeting of the Audit Committee on February 14, 2018, the Audit Committee reports that it has: (i) reviewed and discussed the Company's audited financial statements with management; (ii) discussed with the independent auditors the matters required to be discussed by the statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T; and (iii) received the written disclosures and the letter from the independent accountants required by applicable requirements of the Public Company Accounting Oversight Board 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 review and discussions referred to in Items (i)-(iii) above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's annual report on Form 10-K for the year ended December 31, 2017, for filing with the Securities and Exchange Commission.

The Audit Committee has selected Ernst & Young LLP as the Company’s independent auditors for the year ending December 31, 2018, and has submitted the same to the shareholders for ratification at the Annual Meeting.

COMPENSATION DISCUSSION AND ANALYSIS

Introduction

Overview of Our Compensation System

The Company has a long history of delivery above industry-average financial results, and one of the Company’s goals is to ensure our executive pay has a significant role in attracting and retaining the executive level talent that has achieved these results. Additional primary objectives of our compensation include: aligning executive and employee interests with the interests of our shareholders (appropriately structured so as to not encourage inappropriate risk taking); creating and maintaining an entrepreneurial culture; motivating employees to continue technical developments and improve customer satisfaction; creating and maintaining a teamwork-driven environment; and maintaining performance-based model balancing short-term and long-term performance of individuals and the Company.

The core elements of the Company’s executive compensation plan are base salary, performance-based bonuses, and stock-based incentives. The Compensation Committee believes that these core elements in combination with the ability to “claw-back” performance-based compensation in appropriate circumstances are a solid foundation to continue to increase emphasis on performance-based incentive pay and equity awards and achieve the objectives of our compensation plan. We believe the perquisites and personal benefits we provide to our executive officers are conservative to market.

The objectives of the Company’s executive compensation plan are also achieved by not including pension arrangements and prohibiting option repricing, hedging or monetizing transactions by directors or employees to lock in the value of the Company, and purchasing Company stock on margin, borrowing against Company stock on margin, or pledging of Company stock.

Responsibilities

The Compensation Committee of our Board of Directors is appointed to assist our Board in discharging its responsibilities relating to the compensation of our executives. The Compensation Committee:

• is comprised of three directors, each of whom has been determined by our Board to be independent under applicable standards and none of whom receive any consulting, advisory, or other compensation fee (other than fees for service as Board or committee members)

• operates under and in accordance with the written Compensation Committee Charter

• has a chair that sets meeting agendas and the calendar for meetings

The President and Chief Executive Officer and other members of management may attend meetings of the Compensation Committee at the request of the Committee. The Compensation Committee does, however, meet in executive session as necessary and appropriate. The Compensation Committee has the authority to engage outside consultants and advisors to advise the Committee with respect to compensation of executives, in its discretion.

The Board of Directors has responsibility to annually assess our director compensation program. Members of management attend meetings of the Board at the Board's request, but the Board meets in executive session when required.

Role of Executives in Establishing Compensation

The Compensation Committee is responsible for recommending CEO (now President and CEO) and other executive officer compensation to the Board of Directors for approval in accordance with the Compensation Committee Charter. In the past, the CEO has provided input and made recommendations to the Compensation Committee with respect to compensation decisions for non-CEO executive officers. It is anticipated the President and CEO will continue to do so. The CEO, now President and CEO (along with management) are primarily responsible for making compensation decisions for our other employees within guidelines established by the Compensation Committee. The Compensation Committee does, however, review and approve all stock-based awards and other performance-based bonuses for the CEO, now President and CEO, and other officers. Since the Compensation Committee and the entire Board recognize that the CEO and other executive officers have the greatest opportunity to influence our performance, our Compensation Committee concentrates its efforts on establishing proper rewards and incentives for executive officers. This structure provides our CEO and executive officers the freedom to influence and motivate our employees to positively impact our Company performance within the guidelines established by the Compensation Committee.

22

Compensation Committee Activity

During fiscal year 2017, the Compensation Committee met eleven times and also met in January and February 2018 (and subsequently) to among other things: approve the Compensation Committee Report; review and approve other compensation disclosures included in the Proxy Statement; to review and approve performance-based bonuses; do annual reviews of all executive officers; and to adjust the Company's compensation structures as more fully described herein. Among the activities of the Compensation Committee is a review of each element of compensation payable to each named executive officer, as well as the total compensation payable to them, by use of an executive officer equity compensation tally sheet (including stock appreciation). These tally sheets help reflect compensation for a certain number of previous years so that compensation decisions of the Compensation Committee and the Board can be placed in the appropriate context.

In the last year, consistent with the Compensation Committee Charter, and with the consent of the Compensation Committee, the Company retained an independent compensation consultant, Mercer to advise on certain compensation matters. Mercer's engagement included: an assessment of the Company's existing compensation program; a competitive analysis of a peer-group of publicly-traded organizations, including base salaries, annual incentives, and long-term incentives; plan design alternatives; pay trends; performance metrics; stock ownership guidelines; and employment agreements; and reporting on the same, including certain recommendations for potential changes to executive and director compensation. The Compensation Committee Charter grants the Compensation Committee authority to retain or have retained such consultants. The Compensation Committee did consider the independence of Mercer in assessing the information and recommendations provided by Mercer.

Mercer provided peer group and industry compensation data to both management and the Compensation Committee for executives and directors. Such data was used by the Compensation Committee as a frame of reference for adjusting the Company's compensation structure as more fully described herein, including establishing executive compensation targets for base pay and annual cash bonuses, as well as consideration of long-term equity incentives.

The Company has not wavered from its compensation philosophy to achieve the objectives, which include ensuring its compensation program structure and features align the interests of executives and employees with those of our shareholders. The Compensation Committee did, however, recommend to the Board changes in the Company's compensation model going forward, which are consistent with the Company’s historical compensation philosophy and objectives.

Objectives of Compensation Program

Our compensation program is comprised of three fundamental elements: base salary, performance-based bonuses, and stock-based incentives. These elements are intended to reflect our cultural emphasis on all team members sharing in the financial opportunities and sacrifices at our Company, just as our shareholders do and are intended and structured to avoid encouraging excessive and unnecessary risk taking. The compensation program is designed in light of our desire to maintain an entrepreneurial culture and to incentivize desired performance and growth. The elements of compensation are utilized to accomplish several objectives, including: to attract, motivate, and retain management personnel; encourage continued technical development and improve customer satisfaction; stay competitive for talent; encourage and reward individual achievement as well as overall Company performance; and balance short-term performance and long-term performance by aligning the interests of our team with the interests of our shareholders.

In 2018, the Compensation Committee recognized that certain changes in the Company's compensation model were appropriate in order to continue to achieve the objectives set forth above. As previously disclosed, our compensation program is reviewed and compared to market on a periodic basis, and the most recent such review indicated changes were necessary. The Compensation Committee in its most recent evaluation compared the compensation of our executives to those of an executive compensation peer group (Peer Group).

23

The Peer Group consisted of the following companies:

Allison Transmission Holdings, Inc.	Briggs & Stratton Corporation
Cooper-Standard Holdings	Franklin Electric Co., Inc.
Gentherm Incorporated	Hillenbrand, Inc.
ITT Inc.	LCI Industries
Meritor, Inc.	Modine Manufacturing Company
Shiloh Industries, Inc.	Standard Motor Products, Inc.
Superior Industries International, Inc.	The Timken Company
Tower International Inc.

In reviewing the Peer Group, the Compensation Committee now understands that before any adjustments, our Company's base salaries were at 74% of the market median and below the market 25th percentile; total target cash compensation was 71% of the market median and below the 25th percentile; and long-term incentives fell below market median as well. Before the adjustments described herein, the Company's target total direct compensation was 61% of market median. The Compensation Committee and the Board recognize these levels need to be adjusted to accomplish the objectives of our compensation system as set forth above.

To address the foregoing, the Compensation Committee intends to adjust executive officer base salaries, to modify short-term incentive compensation targets, and to modify long-term incentive equity targets to approach market median, in each case over an appropriate period of time, all as more fully discussed herein.

2017 Compensation Elements in General

As noted above, the compensation program is comprised of three fundamental elements: (1) base salary; (2) bonus; and (3) stock-based incentives. Base compensation for executive officers is predicated primarily on competitive circumstances for managerial talent and positions reflecting comparable responsibility. Historically, base salaries for our employees have been below market, with incentive compensation intended to encourage and implement our entrepreneurial culture. A variety of factors are considered in determining appropriate levels of executive compensation as more fully described herein.

Bonus compensation is comprised of Profit-Sharing Bonus payments and bonuses, including performance-based bonuses for executive officers and certain other key employees. For 2017, all of our full-time employees, including the CEO and other executive officers, were eligible to share in our Profit-Sharing Bonuses. A percentage of pre-tax income after a minimum threshold of profitability has been achieved is paid to eligible employees quarterly. This structure is intended to incentivize employees to produce above industry average financial performance, thereby aligning employee and shareholder interests. During 2017, this Profit-Sharing Bonuses in the total amount of approximately $33.96 million were paid to approximately 5,875 employees. Historically, the Profit-Sharing Bonuses have paid employees between 0% and 25% of base salary, which supplements base salaries, consistent with our philosophy employees win when shareholders win.

In addition, the Company has adopted an additional bonus based on the Profit-Sharing Bonuses already paid (in accordance with the Company's Performance-Based Bonus Plan). Under that plan, certain key employees, including the CEO and executive officers, are eligible to receive a thirteen percent (13%) increase in the Profit-Sharing Bonus percentage for each one percent (1%) by which net sales for the relevant year exceed net sales for the prior year (less payments of Profit-Sharing Bonuses already made for such year). The plan is designed to even further align shareholder return with executive officer compensation, in that incentive is provided to continue growing the Company.

In addition, performance-based bonuses were awarded under the Performance-Based Bonus Plan based on pre-established performance metrics of EBITDA, Diluted Earnings per Share, and Quality (each factor being weighted one-third for 2017). The Compensation Committee selected these measures to provide a balanced focus and because they tend to impact shareholder value. At the beginning of 2017, the Compensation Committee discussed, considered, reviewed, and set a threshold and a target for each of the foregoing performance metrics (based on IHS light vehicle production data, internal estimates of take rates and volumes, and expense budgets). There is no bonus payable under the plan until the pre-established threshold for a performance metric is exceeded and a maximum bonus of ten percent (10%) of base salary is payable for achievement of all targets. Pro-rata bonuses (based on the percentage of the target achieved in excess of the threshold) are payable based upon exceeding the thresholds but not meeting or exceeding the targets.

24

The Compensation Committee met in January and February 2018 to verify the achievement of the above-described additional profit-sharing bonuses and the performance metrics for the performance-based bonuses for 2017. Under the Performance-Based Bonus Plan, the Compensation Committee retains the right, based on performance, to increase bonuses up to twenty-five percent (25%) of such bonus and to pay employee participants bonuses for personal goal achievement of up to twenty-five percent (25%) of base salary as well. The Company has a Clawback Policy such that in the event of a restatement of the Company's financial statements, the bonuses payable under the Performance-Based Bonus Plan may be clawed back.

Stock-based compensation is intended to align the interests of shareholders and executives and other employees by making our executives and other employees shareholders in a meaningful amount. We attempt to foster and maintain an entrepreneurial culture that seems to work best when our employees are owners and, therefore, win when our shareholders win. History and the current climate have confirmed for us that stock-based compensation provides appropriate incentives to incent long-term performance and is also a good retention tool. Stock-based compensation includes stock options and restricted stock.

Stock options are granted under our existing Employee Stock Option Plan, as amended, and restricted stock is granted under our Second Restricted Stock Plan, as amended, each of which has been approved by our shareholders. Our stock-based incentives vest over time to encourage our employees to take a long-term perspective. Employees are now given a choice between stock options or restricted stock. To the extent an employee selects restricted stock, said employee receives one share of restricted stock for each 3.33 number of options to acquire shares that would otherwise have been granted.

Details of Compensation Program Design

The fundamental elements of our compensation program allow compensation to be impacted by our overall performance and by individual performance as well.

Impact of Performance on Compensation

Historically, the Compensation Committee has undertaken a CEO performance review which involves a multi-step process. During 2017, the entire Board of Directors evaluated CEO performance on a variety of factors including leadership, strategic planning, financial results, succession planning, human resources and diversity, communications with the Board, management, employees, and shareholders, external relations, and Board relations.

The Compensation Committee gathered the results of this evaluation. The Compensation Committee then considered these evaluations and discussed the same with the CEO. Based on the foregoing, the Compensation Committee then made CEO compensation recommendations to the entire Board of Directors. Pursuant to this process, the CEO's base salary was determined and approved by the Board. Going forward, all evaluations, as contemplated herein, will be undertaken at the same time for all executive officers, including the President and CEO. Through these evaluation processes, the Compensation Committee and the Board can exercise positive or negative discretion concerning compensation decisions. Evaluations of our employees otherwise take place on or about the employee's anniversary date of employment except executive officers, which occur in February of each year to coincide with the Compensation Committee verification of achievement of the performance metrics related to payment of annual incentive bonuses and equity award grants.

The Compensation Committee considers the foregoing factors in varying degrees. In its 2017 review of CEO performance which occurred in August 2017, the Compensation Committee and the Board highlighted positive reviews with respect to financial results and personnel development. Strategic and succession planning, along with product development, were also covered in the 2017 CEO performance review.

Specifics on Elements of Compensation for 2017

The "Summary Compensation Table for 2017" shows the base salary, bonuses (including performance-based bonuses and personal goal achievement bonuses), restricted stock awards, stock option awards and other compensation for each of our named executive officers. Total compensation for each applicable named executive officer is also reflected in that Table. The "Grants of Plan-Based Awards for 2017" Table sets forth stock-based compensation. The "Outstanding Equity Awards at Fiscal Year-End December 31, 2017," Table and the "Option Exercises and Stock Vested for 2017" Table further demonstrate efforts to align our executive officers' interests with those of our shareholders. We continue to believe these compensation elements and the mix of these elements are appropriate for the Company given its culture, performance, industry, and current opportunities and challenges.

25

The 2017 base salaries for our named executive officers are set forth in the "Summary Compensation Table for 2017." The Company approved guidelines for 2017 that salaried employees, including executive officers, are eligible for an increase in base salary of up to five percent (5%) per year for performance alone, and up to ten percent (10%) per year total if increased responsibilities are undertaken (or, potentially more in the case of a promotion). For 2017, our CEO received a two and a half percent (2.5%) increase in base pay, based on Company guidelines. Based on the information set forth above, including the base salaries of executive officers in companies to the Peer Group, the Compensation Committee set base salaries in 2017 and 2018 for executive officers as follows:

Executive Officer	2017 Base Salary	2018 Base Salary
Steve Downing, President & CEO	$425,250	$650,000
Kevin Nash, Vice President of Finance, CFO and Treasurer	$226,736	$340,000
Neil Boehm, Vice President of Engineering and CTO	$233,733	$333,000
Matt Chiodo, Vice President of Sales	$240,252	$336,000
Scott Ryan, Assistant General Counsel and Corporate Secretary	$240,772	$315,000
Joe Matthews, Vice President of Purchasing	$175,032	$205,000

It is the current intention of the Compensation Committee to approach the Peer Group median over time.

Profit-Sharing Bonuses and other performance-based bonuses, as described herein, and personal goal achievement bonuses for named executive officers are also set forth in the "Summary Compensation Table for 2017." The Company has approved a guideline such that employees, including executive officers, are eligible for personal goal achievement bonuses of up to 50 percent of base salary (or, potentially more, in the case of exemplary performance). The additional profit-sharing bonuses and performance-based bonuses earning in 2017 under the Performance-Based Bonus Plan are set forth in the Non-Equity Incentive Plan Compensation column of the "Summary Compensation Table for 2017." Personal goal achievement bonuses earned in 2017 are set forth in the Bonus Column of the "Summary Compensation Table for 2017."

For 2017, participants in the Performance-Based Bonus Plan became eligible for an increase in the Profit-Sharing Bonus percentage due to a seven percent (7%) year-over-year increase in sales, with such bonus calculated as set forth herein.

With respect to the performance metrics for the performance bonus under the Performance-Based Bonus Plan for 2017:

Performance Metric	Weighting Factor	Threshold	Target	Actual Result
EBITDA	1/3	$540,297,328	$636,350,187	$622,929,258
Diluted Earnings Per Share	1/3	$1.07	$1.26	1.41
Quality	1/3	*	*

*Quality thresholds and targets are a non-variable calculation based on parts per million plus over-all corporate cost of quality.

In January and February 2018, the Compensation Committee verified achievement of the year-over-year increase in sales and the performance metrics under the Performance-Based Bonus Plan for 2017. For 2017, each executive officer was awarded an Additional Profit-Sharing Bonus and a performance bonus as set forth in the "Summary Compensation Table for 2017," in Part III, Item 11 of the Company's Form 10-K for the year ended December 31, 2017, and as set forth below:

Joseph Matthews, Vice President, Purchasing	$	28,488	$	20,873	$	22,478

*Includes discretionary increases authorized by the Board of Directors in accordance with the terms of the Performance Plan.

In addition to the above Performance Plan payments, the Board of Directors approved bonuses for personal goal achievement disclosed in the aforementioned table on February 15, 2018.

Personal goal achievement bonuses also reflect our Compensation Committee's and Board of Directors' positive and negative discretion. See the Gentex Annual Incentive Performance-Based Bonus Plan for updates. It is the current intention of the Compensation Committee to approach Peer Group median for such annual incentives.

Our named executive officers are also eligible to receive grants of stock options under our Employee Stock Option Plan and grants of restricted stock under our Second Restricted Stock Plan. For 2017, the Company approved guidelines so that stock option awards up to an established percentage may be made under our Employee Stock Option Plan and restricted stock awards of up to an established percentage may be made under our Second Restricted Stock Plan. During 2017, executive officers were granted between 5,040 and 21,280 stock option shares and between 1,820 and 7,560 shares as restricted stock awards. These awards are predicated on both individual and company performance, while creating incentives to help achieve our long-term goals, align employee interests with those of our shareholders, and retain executive talent. With respect to such stock option awards, during 2017 executive officers, like all employees, could elect to take restricted stock in lieu of such stock options (one share of restricted stock for each 3.33 stock options as noted above). Such elections are noted in the "Grant of Plan-Based Awards for 2017" Table.

Our Employee Stock Option Plan, as amended and restated, makes stock options generally available to all of our salaried employees. All options are granted to employees around the end of the quarter in which their anniversary date of employment occurs at scheduled meetings of the Compensation Committee (except in the case of named executive officer and other officer stock option grants, which are done when approved by the entire Board of Directors as discussed herein). Stock options are only granted at their fair market value on the date of Compensation Committee meetings with all such grants being reviewed and approved by the Compensation Committee (except named executive officer stock option grants, which are only granted at their fair market value on the date approved by the entire Board). In the past, stock option awards to officers generally have had a seven-year term and become exercisable (as long as employment continues), for 20 percent of the shares on each anniversary of the grant date commencing on the first anniversary of the grant date, although a five-year term might be used in order to accommodate certain circumstances. Stock options for other employees generally carry a five- to seven-year term and similarly vest over time.

Restricted stock awards are granted at the discretion of the Compensation Committee at scheduled meetings of the Compensation Committee (except in the case of named executive officer and other officer restricted stock awards which are made when approved by the entire Board of Directors as noted herein). Historically, grants of restricted stock to eligible employees, including executive officers and other officers, are considered once every three years for each eligible employee. The Compensation Committee now grants restricted stock awards annually for named executive officers and other officers at the time of the reviews of such individuals. Usually these share grants are restricted for five years from the date of grant, and as such are viewed as a retention tool. Dividends are paid on restricted shares so granted if, and to the extent, we pay dividends on our common stock. The vesting schedules associated with stock option and restricted stock awards, in part, discourage excessive and unnecessary risk-taking (especially when considered in connection with the stock ownership guidelines for executive officers).

27

Based on the information set forth above, the Compensation Committee also made the following equity grants in 2018:

Executive Officer	Position	Stock Option Grant	Restricted Share Award
Steve Downing	President and CEO	101,000	68,000
Kevin Nash	Vice President of Finance, CFO and Treasurer	27,000	8,000
Neil Boehm	Vice President of Engineering and CTO	30,000	8,000
Matt Chiodo	Vice President of Sales	30,000	8,000
Scott Ryan	Assistant General Counsel and Secretary	25,000	8,000
Joseph Matthews	Vice President of Purchasing	6,500	3,000

These stock option grants and restricted stock awards were approved pursuant to the Company's shareholder approved Employee Stock Option Plan and shareholder approved Second Restricted Stock Plan, respectively. The stock option grants are ten-year options that become exercisable as long as employment of the Company continues for 25 percent of such shares on each anniversary of the grant date commencing with the first anniversary of the grant date. The exercise price is the closing price of the stock on the grant date. The restricted stock awards vest at the fourth anniversary of the grant, except for 37,000 shares of restricted stock granted in recognition of Steve Downing's promotion to President and CEO, which vest on the fifth anniversary of the grant. The Compensation Committee will in the near future determine the best approach to creating long-term performance metrics associated with equity compensation awards, which will be in addition to vesting requirements. It is the current intention of the Compensation Committee to approach Peer Group median in this regard as well.

On February 15, 2018, the Board of Directors amended and restated the Gentex Corporation Performance-Based Bonus Plan as the Amended and Restated Annual Incentive Performance-Based Bonus Plan (Amended Plan) to: further emphasize performance-based compensation, provide executive officers, officers, and other key employees of the Corporation with appropriate incentives concerning corporate and individual performance, and enhance the alignment between such key employees and shareholders. The Amended Plan is administered by the Compensation Committee of the Board, which has discretion to determine the executive officers, officers, and other employees eligible to participate in the Plan. Only employees of the Corporation are eligible to participate in the Amended Plan.

In lieu of participating in the Profit Sharing Bonuses paid to all employees, annual performance bonuses are available to participants based on the achievement of the following performance metrics:

(a) Revenue, which will have a 33.33% weighting;

(b) Operating Income, which will have a 33.33% weighting; and

(c) Earnings Per Diluted Share, which will have a 33.33% weighting.

For purposes of determining annual performance bonuses, the Compensation Committee will annually establish a threshold, target, and maximum for each applicable performance metric, along with incentive ratios applicable to each Participant with respect to such threshold, target, and maximum. The applicable incentive ratio is a percentage of base pay for each Participant, designated by the Compensation Committee, which is then multiplied by the weighting factor of a particular performance metric to determine the amount of a performance bonus payable to a Participant to the extent the threshold, target, or maximum for a performance metrics is met or exceeded. To the extent performance exceeds the established threshold or target, as applicable, for any performance metric, but does not meet the established target or maximum, as applicable, a pro-rata portion of the potential bonus payable will be paid as a performance bonus (based on the percentage of the target or maximum, as applicable, achieved in excess of the threshold or target, as applicable). Calculations of performance bonuses will be determined using linear interpolation for performance between threshold and target and between target and maximum. The annual performance bonus is cash-based and intended to motivate and reward employees based on Company metrics that drive shareholder value.

Notwithstanding the foregoing, based on any criteria it establishes in its discretion, the Committee reserves the right to increase (or decrease) a performance bonus for personal goal achievement in an amount so as not to in any event exceed 250% of base compensation. Any and all bonuses under the Plan are payable in accordance with policies and procedures established by the Compensation Committee.

28

For 2018, the Compensation Committee has established incentive ratios of twenty-five percent (25%) of base salary upon achievement of the threshold and up to one hundred percent (100%) of base salary for the President and CEO and seventy-five percent (75%) of base salary for the other named executive officers for achievement of performance in excess of the threshold up to the target, plus incentive ratios of zero percent (0%) of base salary to one hundred percent (100%) of base salary for the President and CEO and seventy-five percent (75%) of base salary for the other named executive officers for the achievement of performance in excess of target up to the maximum. At its February 2018 meeting, the Compensation Committee also established thresholds, targets, and maximums for the Revenue, Operating Income, and Earnings Per Diluted Share performance metrics. It is the intention of the Compensation Committee to approach Peer Group median in this regard as well.

All other compensation for named executive officers set forth in the "Summary Compensation Table for 2017" includes "matching" contributions by the Company pursuant to our 401(k) plan, restricted stock dividends, the personal use of automobiles by certain executive officers, certain costs associated with the personal use of Company aircraft, and membership fees at a local country club, as detailed in the notes to the "Summary Compensation Table for 2017." We make available to our executives Company aircraft for personal use, provided it does not conflict with any business purpose for the aircraft. All executives are assessed the value of the incremental costs of personal use of Company aircraft. The cost to the Company related to personal use of Company aircraft is calculated using the SIFL (Standard Industry Fare Level) rates as outlined by the IRS in accordance with Treasury Regulation Section 1.61-21 (Taxation of fringe benefits). Certain costs associated with the personal use of Company aircraft are considered a taxable fringe benefit as reflected in the notes to the "Summary Compensation Table for 2017." For tax purposes, the additional income that is considered a taxable fringe benefit is subject to income inclusion as reflected in the notes to the "Summary Compensation Table for 2017."

Director Compensation

Our Board of Directors has responsibility for periodically assessing our director compensation program.

Each director who was not an employee of the Company received in 2017:

• $14,400 annual directors' retainer fee ($3,600 per quarter);

• $2,100 for each Board meeting attended;

• $1,500 for each Committee meeting attended; and

• An option to purchase 7,000 shares of our common stock.

The Lead Independent Director receives an additional retainer fee in the amount of $10,000 for 2017. The Chairs of our Compensation and Audit Committees also received an additional retainer fee in the amount of $5,000 for each committee in 2017. The non-employee directors annual option to purchase 7,000 shares of our common stock is at a price per share equal to the closing price of our stock on the NASDAQ on the date of each annual meeting of shareholders in accordance with our shareholder approved 2012 Amended and Restated Non-employee Director Stock Option Plan, as amended. See the "Director Compensation Table for 2017." Like executives, Board members may make personal use of Company aircraft if such use does not conflict with any business purpose for the aircraft. The cost to the Company related to such personal use by directors is calculated using SIFL (Standard Industry Fare Level) rates as discussed above. We believe this director compensation in conservative to market.

For 2018, the Board of Directors adjusted the annual compensation of directors who are not employees as follows:

Annual retainer - $80,000

Chair of the board retainer - $75,000

Audit Committee Chair retainer - $12,500

Compensation Committee Chair retainer - $10,000

Nominating and Corporate Governance Committee Chair retainer - $10,000

Audit Committee Member retainer - $7,500

Compensation Committee Member retainer - $5,000

Nominating and Corporate Governance Committee Member - $5,000

An option to purchase 7,000 shares of our common stock.

29

All of said amounts, other than the stock option grant, are payable quarterly. The Company also retained Mercer to provide market comparisons, review of peer groups, and trends in terms of director pay. The Board determined director compensation, like officer compensation, is significantly below peer group median. It is the Board’s intention to approach peer group median in this regard as well.

Stock Ownership

The Company has adopted Stock Ownership Guidelines (*) providing that executive officers should own three times their annual salaries in Company common stock and directors should own two times their annual director fees in Company common stock. As noted above, such guidelines help discourage excessive and unnecessary risk-taking in the context of the Company’s emphasis on stock-based compensation. In addition, the Company's Anti-Hedging and Anti-Pledging Policy prohibit directors and executive officers from leveraging their ownership of Company stock or pledging Company stock to secure personal loans.

Impact of Regulatory Requirements

In making compensation design and award decisions, we have considered the ability to deduct compensation in accordance with Internal Revenue Code Section 162(m). We have also considered the impact of Section 16 of the Securities and Exchange Act of 1934 and rules promulgated thereunder. Since we do not currently have a deferred compensation plan, consideration of the impact of Internal Revenue Code Section 409A in compensation design and award decisions has not been significant. We have also in the past undertaken certain actions disclosed in our SEC filings with respect to the impact of expensing stock-based awards (including stock options) under FASB ASC Topic 718. The executive compensation disclosure rules applicable to annual reports and proxy statements with respect to the disclosure of compensation-related risks for all employees, certain matters related to compensation consultants, reporting of equity awards in the Summary Compensation table, and the provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act related to compensation have had no material impact on our decisions regarding compensation. The shareholder advisory vote on named executive officer compensation occurring this year, as well as future shareholder advisory votes on named executive officer compensation will be considered by the Compensation Committee and Board of Directors in making future compensation decisions.

Pay Ratio

As a result of recently adopted rules under the Dodd-Frank Act, beginning with our 2018 Proxy Statement, the SEC now requires disclosure of the CEO to median employee pay ratio. In 2017, the CEO's annual total compensation was $922,988 as reflected in the "Summary Compensation Table for 2017." Our median employee's annual compensation for 2017 was $46,144. As a result, we estimate that the CEO's annual total compensation was approximately 20 times that of our median employee.

Conclusion

We have reached the conclusion that each individual element of compensation, as well as the total compensation, delivered to our named executive officers and to our directors during 2017 and the changes for 2018 are reasonable, appropriate, and in the best interests of our Company and our shareholders. That determination is based on a continuation of our compensation philosophy, objectives, and practices which we believe align both the short-term and long-term interests of our employees with those of our shareholders. It remains the case that each element of our compensation program is important to accomplishing the Company's goals of creating an entrepreneurial environment so that our employees are motivated to remain with us, individually perform to the best of their abilities, and focus on our long-term success.

(1)     The Grant Date is the date when the Compensation Committee's recommendation was approved by the entire Board of Directors.

(2) For 2018, the Compensation Committee has established incentive ratios of twenty-five percent (25%) of base salary upon achievement of the threshold an up to one hundred percent (100%) of base salary for the President and CEO and seventy-five percent (75%) of base salary for the other named executive officers for achievement of performance in excess of the threshold up to the target, plus incentive ratios of zero percent (0%) of base salary to one hundred percent (100%) of base salary for the President and CEO and seventy-five percent (75%) of base salary for the other named executive officers for the achievement of performance in excess of target up to the maximum. At its February 2018 meeting, the Compensation Committee also established thresholds, targets, and maximums for the Revenue, Operating Income, and Earnings Per Diluted Share performance metrics. Mr. Matthews is no longer an executive officer, but remains an employee of the Company.

(3)    The option grants for Mr. Matthews are seven-year options that become exercisable, as long as the employment with the Company continues, for 20 percent of the shares on each anniversary of the grant date commencing with the first anniversary of the grant date. Messrs. Downing, Nash, Ryan, Boehm, and Chiodo, elected to receive restricted shares in lieu of their approved stock option grants for 2017.

(4) The exercise price was the closing price of the stock as of the day when the Compensation Committee's recommendation was approved by the entire Board of Directors. The exercise price may be paid in cash, in shares of the Company's common stock, and/or by the surrender of the exercisable options valued at the difference between the exercise price and the market value of the underlying shares.

(5) Stock option grant date fair values are based on the Black-Scholes option valuation model in accordance with FASB ASC Topic 718. Restricted stock awards represent the aggregate value at the date of grant for shares of common stock awarded under the Company’s Second Restricted Stock Plan. See the Company’s Annual Report (Footnote 5) for the year ended December 31, 2017, for the assumptions made in the valuation of stock options.

(1)    These options become exercisable, as long as employment with the Company continues, for 20 percent of the shares on each anniversary of the grant date commencing with the first anniversary of the grant date. Mr. Matthews has 2,356 five-year options that become exercisable, as long as employment with the Company continues, for 25 percent of the options on each anniversary of the grant date commencing with the first anniversary of the grant date. These options were granted to Mr. Matthews before he became an executive officer of the Company. Mr. Ryan has 2,080 five-year options that became exercisable, as long as employment with the Company continues, for 25 percent of the options granted on each anniversary of the grant date commencing with the first anniversary of the grant date. These options were granted to Mr. Ryan before he became an executive officer of the Company.

(2)    The exercise price was the closing price of the stock on the date the Compensation Committee met to approve the option grants, or when the Compensation Committee's recommendation was approved by the entire Board of Directors. The exercise price may be paid in cash, in shares of the Company's common stock, and/or by the surrender of the exercisable options valued at the difference between the exercise price and the market value of the underlying shares.

(3)    Assuming continued employment with the Company, restrictions on shares lapse upon the expiration of five years from the date of grant. Dividends are and will be paid on these shares if, and to the same extent, paid on the Company's common stock.

(1) Directors who are employees of the Company receive no compensation for services as a director. Directors who are not employees of the Company received a director's retainer in the amount of $14,400 per year ($3,600 per quarter) plus $2,100 for each meeting of the Board attended and $1,500 for each committee meeting attended during 2017. Directors who chaired the Compensation Committee and/or the Audit Committee each received an additional retainer fee in the amount of $5,000 per year during 2017. The Lead Independent Director received an additional annual retainer fee in the amount of $10,000 during 2017 as well. The foregoing compensation has been adjusted for 2018 as set forth herein.

(2) Immediately following each Annual Meeting of Shareholders non-employee directors are entitled to receive an option to purchase 7,000 shares of the Company's common stock at a price per share equal to the closing price of the Company's stock on NASDAQ on that date. Each option has a term of ten years and becomes exercisable in full six months after the date of grant. For each outstanding stock option award, the value shown is the aggregate grant date fair value computed in accordance with FASB ASC Topic 718 (as opposed to what is included in the Company's financial statements). See the Company’s Annual Report (Footnote 5) for the years ended December 31, 2017, 2016, and 2015 for the assumptions made in the valuation of stock options.

(3) The Company also makes Company aircraft available to directors for personal use if such use does not conflict with any business purpose for the aircraft. The cost of the flight is calculated using the SIFL (Standard Industry Fare Level) rates published by the IRS in accordance with Treasury Regulation Section 1.61-21 (Taxation of fringe benefits).

The following table summarizes securities issued and to be issued under the Company’s equity compensation plans as of December 31, 2017:

Compensation Committee Interlocks and

Insider Participation

The Compensation Committee, which includes Messrs. Goode (Chair), Schaum, and Wallace, is currently comprised solely of members of the Company’s Board of Directors who are independent under the applicable NASDAQ listing standards. The Compensation Committee is responsible for supervising the Company’s executive compensation arrangements, including the making of decisions with respect to the award of stock-based incentives for executive officers.

CERTAIN TRANSACTIONS

The Audit Committee of the Company reviews and approves all related party transactions in accordance with its Charter. The Code of Business Conduct and Ethics requires directors, officers, and employees to report these types of matters. In addition, the Company uses questionnaires for its directors and officers annually in part to discover any unreported related-party transactions. The approval of the Audit Committee is required for related-party transactions.

Since 1978, prior to the time the Company became a publicly held corporation, the Company has leased a building that previously housed its main office, manufacturing and warehouse facilities, and currently houses production operations for the Company’s fire protection products. The lessor for that building is G & C Associates, a general partnership, and nearly all of the partnership interests in G & C Associates are held by persons related to Fred Bauer. The lease is a "net" lease, obligating the Company to pay all expenses for maintenance, taxes, and insurance, in addition to rent. During 2017, the rent paid to this partnership was $52,153, and the rent for the current fiscal year until the time of acquiring is the same (as it has been for a number of years). The Board of Directors believes that the terms of this lease are at least as favorable to the Company as could have been obtained from unrelated parties. During the first quarter of 2018, the Company acquired this building for $950,000 as previously disclosed.

The Company is highly selective, and hires new employees based upon merit. Employees may also be eligible for certain other benefits which are similarly available on no less favorable terms to other employees of the Company at the same level and pay rate. Family members of any employee are not discouraged from seeking employment.

RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS – PRINCIPAL ACCOUNTING FEES AND SERVICES

The Audit Committee and Board of Directors have selected, and submits to shareholders for ratification, Ernst & Young LLP to serve as the Company’s independent auditors for the fiscal year ending December 31, 2018. The following fees were billed by Ernst & Young LLP, the Company’s independent auditors, for the services provided to the Company during the fiscal years ended December 31:

	2017		2016
Audit Fees	$	440,000	$	420,000
Audit-Related	165,000		42,000
Tax Fees	—		—
All Other	—		—
Total	$	605,000	$	462,000

Audit fees include the annual audit of the Company’s consolidated financial statements, the audit of internal control over financial reporting, and timely quarterly reviews. Audit-Related fees principally consist of consultations concerning accounting matters associated with the annual audit, incremental consent filings, and other out-of-scope work. Tax fees principally consist of fees for tax advice. All non-audit services, including those indicated above, are pre-approved by the Audit Committee pursuant to the Revised Audit Committee Procedures for Approval of Audit and Non-audit Services by Independent Auditors, which is attached as Appendix A to this Proxy Statement.

The Audit Committee periodically evaluates the Company's independent auditor. The quality of the staff of Ernst & Young LLP, historical and current performance, expertise in the Company's industries, reasonableness of fees, and independence are all factors that went into the Audit Committee's decision to select Ernst & Young LLP as the Company's independent auditors. The audit engagement partner for the Company rotates every five years and the Audit Committee is involved in the selection of a new audit engagement partner. Although ratification of the independent auditors by the Company’s shareholders is not legally required, our Audit Committee and Board of Directors believes that submission of this matter to the shareholders follows sound business practice and is in the best interest of shareholders in the current environment. If the shareholders do not approve the selection of Ernst & Young LLP, the selection of such firm as our independent auditors will be reconsidered by the Audit Committee. Accordingly, you may vote on the following resolution at the 2018 Annual Meeting of Shareholders:

RESOLVED, that Ernst & Young LLP be and hereby is ratified to serve as the independent auditors of the Company for the fiscal year ended December 31, 2018.

A representative of Ernst & Young LLP is expected to be present at the Annual Meeting to respond to appropriate questions and will have an opportunity to make a statement if they desire.

The Board of Directors unanimously recommends a vote FOR the ratification of Ernst & Young LLP to serve as the Company's independent auditors for fiscal year ended December 31, 2018.

37

ADVISORY VOTE ON EXECUTIVE COMPENSATION

As described in the detail under the Compensation Discussion and Analysis, the Company's compensation system is intended to create and maintain an entrepreneurial culture, motivate employees to continue technical developments and improve customer satisfaction, and create and maintain teamwork. The Company continues to emphasize performance-based compensation so that the interests of our named executive officers (and all salaried employees) are aligned with the interests of our shareholders, while remaining appropriately structured so as not to encourage inappropriate risk taking. Shareholders are encouraged to read the Compensation Discussion and Analysis, the Company compensation tables, and the related narrative disclosure.

In accordance with certain legislation, the Company is providing shareholders with an advisory (nonbinding) vote on compensation programs for named executive officers (sometimes referred to as "say-on-pay"). Accordingly, you may vote on the following resolution at the 2018 Annual Meeting of Shareholders:

RESOLVED, that the compensation of the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including Compensation Discussion and Analysis, compensation tables, and narrative disclosure is hereby APPROVED.

This vote is non-binding. The Board of Directors and the Compensation Committee, which is comprised of independent directors, expect to take into account the outcome this advisory vote when considering future executive compensation decisions, to the extent they can determine the cause or causes of any significant negative voting results.

The Board of Directors unanimously recommends that you vote FOR the approval, on an advisory basis, of the compensation of our named executive officers as disclosed pursuant to Item 402 of Resolution S-K, including Compensation Discussion and Analysis, compensation tables, and narrative disclosure.
