PROXY STATEMENT

ANNUAL MEETING OF SHAREHOLDERS

March 10, 2023

This Proxy Statement is being furnished to shareholders of EMCORE Corporation (the “Company”) as of the close of business on January 12, 2023 (the “Record Date”), in connection with the solicitation on behalf of the Board of Directors of the Company (the “Board” or the “Board of Directors”) of proxies for use at the 2023 Annual Meeting of Shareholders (the “Annual Meeting”) to be held at 8:00 A.M. Pacific Time, on March 10, 2023, at the Company’s office located at the Hilton Pasadena, 168 S Los Robles Ave., Pasadena, CA 91101, or at any adjournments or postponements thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders. This Proxy Statement and the related proxy materials are first being furnished to shareholders beginning on or about January 24, 2023. Shareholders should review the information provided herein in conjunction with the Company’s 2022 Annual Report to Shareholders.

INTERNET AVAILABILITY OF PROXY MATERIALS

This Proxy Statement and the Company’s 2022 Annual Report for the fiscal year ended September 30, 2022 (“fiscal 2022”) are available on the Internet at www.proxydocs.com/EMKR. These materials will also be available under the “Investors” tab on our corporate website (www.emcore.com) beginning on or about January 24, 2023. The other information on our corporate website does not constitute part of this Proxy Statement.

The Company has elected to furnish its proxy materials over the Internet in accordance with applicable rules of the Securities and Exchange Commission (the “SEC”) rather than mailing paper copies of this Proxy Statement and the Company’s 2022 Annual Report to all shareholders. On or about January 24, 2023, the Company commenced the mailing to its shareholders of a Notice of Internet Availability of Proxy Materials (the “Notice of Internet Availability”) directing shareholders to the website referenced above where they can access this Proxy Statement and the Company’s 2022 Annual Report and view instructions on how to submit a proxy or voting instructions via the Internet or by telephone. If shareholders wish to receive a paper copy of the Company’s proxy materials, please follow the instructions included in the Notice of Internet Availability. Shareholders who have elected not to receive a Notice of Internet Availability or delivery of their proxy materials electronically by e-mail will receive a printed copy of the proxy materials by mail.

PURPOSES OF THE MEETING

At the Annual Meeting, the Company’s shareholders will consider and vote upon the following matters:

1

Unless contrary instructions are indicated on the proxy you submit, all shares represented by valid proxies received pursuant to this solicitation (and that have not been revoked in accordance with the procedures set forth below) will be voted in accordance with the recommendation of the Board of Directors as follows:

In the event a shareholder specifies a different choice by means of a properly submitted proxy, such shareholder’s shares will be voted in accordance with the specification so made. In addition, your shares will be voted as the proxyholders may determine in their discretion upon any other proposals as may properly come before the Annual Meeting.

OUTSTANDING VOTING SECURITIES AND VOTING RIGHTS

As of the close of business on the Record Date, the Company had 37,910,860 shares of no par value common stock (“Common Stock”) outstanding. Each shareholder of record on the Record Date is entitled to one vote on all matters presented at the Annual Meeting for each share of Common Stock held by such shareholder. The presence, either in person or by properly executed proxy, of the holders of the majority of the shares of Common Stock entitled to vote at the Annual Meeting is necessary to constitute a quorum at the Annual Meeting. Attendance at the Annual Meeting will be limited to shareholders as of the Record Date, their authorized representatives, and guests of the Company.

If your shares of Common Stock are registered directly in your name with American Stock Transfer & Trust Company, LLC (“AST”), as of the Record Date, you may vote:

If your shares are held by a bank, broker or other nominee, you are a beneficial owner of those shares rather than a shareholder of record. If you are a beneficial owner, your bank, broker or other nominee will forward you the Notice of Internet Availability or a complete set of the proxy materials, together with a voting instruction form. As a beneficial owner, you have the right to direct your bank, broker or other nominee how to vote your shares by following the voting instructions provided by your bank, broker or other nominee. Please refer to the proxy materials forwarded by your bank, broker or other nominee for instructions regarding the methods available to vote your shares (Internet, telephone or mail). Please note that if your shares of Common Stock are held by a bank, broker or other nominee and you wish to vote in person at the Annual Meeting, you must obtain a “legal proxy” from the bank, broker or other nominee that holds your shares giving you the right to vote in person at the Annual Meeting.

2

Except as noted below, if you are a holder of record, you may use the Internet or any telephone to transmit your voting instructions or, if you received a printed set of the proxy materials, you may vote by mail by completing, signing, dating and returning the proxy card enclosed with the proxy materials you received before the polls close at the Annual Meeting. If you are a shareholder of record, your proxy, whether submitted by telephone, via the Internet or by mail, may nevertheless be changed or revoked at any time prior to the voting thereof at the Annual Meeting at your discretion either by (i) sending to the Company’s Secretary a written notice of revocation, (ii) by voting the shares covered thereby in person at the Annual Meeting or (iii) by submitting another proxy dated subsequent to the date of the initial proxy. Please note that attendance at the Annual Meeting will not by itself constitute revocation of a proxy. If you are a beneficial owner, please refer to the voting instructions provided by the bank, broker or other nominee that holds your shares for information about the deadline for voting and instructions on how to change or revoke any previously submitted voting instructions.

The vote required for approval of each of the proposals before the shareholders at the Annual Meeting is as follows (and as summarized in the table below):

For Proposal I — Election of Directors, each nominee for director will be elected by a plurality of the votes cast in person or by proxy at the Annual Meeting. Each shareholder may vote the number of shares of Common Stock held as of the Record Date by that shareholder for the nominees or may withhold voting such shares from the nominees. The five nominees who receive the most votes that are properly cast at the Annual Meeting will be elected to the Board of Directors.

For each of Proposal II — Amendment to the 2019 Equity Incentive Plan, Proposal III — Advisory Vote on Executive Compensation and Proposal V — Ratification of the Appointment of Independent Registered Public Accounting Firm, an affirmative vote of a majority of the votes cast and entitled to vote on such proposal at the Annual Meeting is required to approve each such proposal. Each shareholder may vote for, vote against or abstain from voting on each of these proposals. For Proposal IV – Advisory Vote on Frequency of Votes on Executive Compensation, the number of years receiving a vote of a majority of the votes cast on the proposal at the Annual Meeting will be considered our shareholders’ recommendation for how often we should hold a shareholder advisory vote on executive compensation. In the event none of the three frequency choices receives a majority of the votes properly cast at the Annual Meeting, the Board of Directors will take into account the results of the vote on this proposal when determining how frequently to hold a shareholder advisory vote on executive compensation.

A broker non-vote occurs when a broker, who has not received voting instructions from the beneficial owner of the shares, does not vote on a non-routine proposal because the broker does not have discretionary authority to vote on such proposal, but the broker does exercise its discretionary authority to vote the beneficial holder’s shares on at least one “routine” matter at the Annual Meeting. Proposal V — Ratification of the Appointment of Independent Registered Public Accounting Firm is considered a “routine” matter under applicable stock exchange rules while the other proposals at the Annual Meeting are considered “non-routine.” If you hold your shares through a broker and do not provide voting instructions to the broker, then under applicable stock

3

exchange rules governing your broker, the broker may vote your shares in its discretion with respect to Proposal V above, but may not vote your shares with respect to any of the other proposals. If no voting instructions are received by the broker that holds your shares and your broker exercises its discretion to vote your shares on Proposal V, your shares will constitute a broker non-vote on each of Proposals I through IV.

In regards to Proposal I — Election of Directors, any shares not voted “FOR” a particular nominee (whether as a result of “withhold” votes or broker non-votes) will not be counted in such nominee’s favor and will have no effect on the outcome of the election. In regards to each of Proposal II — Amendment to the 2019 Equity Incentive Plan, Proposal III — Advisory Vote on Executive Compensation, and Proposal IV – Advisory Vote on Frequency of Votes on Executive Compensation, broker non-votes are not included in the tabulation of the voting results and, therefore, they do not have any effect on the voting results for these proposals. Broker non-votes do not exist for Proposal V — Ratification of the Appointment of Independent Registered Public Accounting Firm, as that proposal is considered a “routine” matter. Abstentions are not treated as votes cast at the Annual Meeting; and therefore, will have no effect on the outcome of the vote for any of Proposals II through V. Withhold votes, abstentions and broker non-votes will be counted for purposes of determining whether a quorum is present at the meeting.

Please note that the proposals regarding the ratification of the appointment of our independent registered public accounting firm and approval of executive compensation are advisory only and will not be binding on the Company or the Board. The results of the votes on those advisory proposals will be taken into consideration by the Company, the Board or the appropriate committee of the Board, as applicable, when making future decisions regarding these matters.

INFORMATION CONCERNING THE PROXY SOLICITATION

The cost of preparing and making available this Proxy Statement, the Notice of Annual Meeting of Shareholders, and the proxy is borne by the Company. In addition to the use of the Internet, employees of the Company may solicit proxies personally and by telephone. The Company’s employees will receive no compensation for soliciting proxies other than their regular salaries. Solicitation of proxies may be made by additional mailings, electronic mail, telephone or in person by directors, officers or regular employees of the Company. The Company may request banks, brokers and other custodians, nominees, and fiduciaries to forward copies of the proxy material to their principals and to request authority for the execution of proxies. The Company will reimburse such persons for their expenses in so doing. We have also retained Alliance Advisors LLC to assist in the solicitation of proxies and related services, for a fee estimated to be approximately $15,000 plus an amount to cover expenses. In addition, we have agreed to indemnify Alliance Advisors LLC against certain liabilities arising out of or in connection with their engagement.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” EACH DIRECTOR NOMINEE LISTED ABOVE UNDER PROPOSAL I FOR ELECTION TO THE BOARD OF DIRECTORS AT THE ANNUAL MEETING. Unless otherwise instructed, the proxyholders will vote all properly submitted proxies “FOR” each director nominee listed above under Proposal I.

GOVERNANCE OF THE COMPANY

Board of Directors

The Board of Directors oversees the Company’s business and affairs pursuant to the New Jersey Business Corporation Act and the Company’s Certificate of Incorporation and Amended and Restated Bylaws. The Board of Directors is the ultimate decision-making body of the Company, except on matters reserved for the shareholders.

Board Leadership Structure

The Board believes it is important to retain its flexibility to allocate the responsibilities of the offices of the Chairman of the Board and Chief Executive Officer of the Company in any way that is in the best interests of the Company and the shareholders at a given point in time. The Board believes that the decision as to who should serve as Chairman of the Board and Chief Executive Officer, and whether these offices should be combined or separate, should be assessed periodically by the Board, and that the Board should not be constrained by a rigid policy mandating that such positions be separate. The Company currently separates the roles of Chief Executive Officer and Chairman of the Board. Mr. Domenik, an independent director, currently serves as Chairman of the Board.

The Board recognizes that the roles of Chief Executive Officer and Chairman of the Board are distinct. While the Chief Executive Officer is responsible for setting the strategic direction for the Company and for the day-to-day leadership and performance of the Company, the Chairman of the Board provides guidance to the Chief Executive Officer and sets the agenda for, and presides over, meetings of the Board of Directors. The Board believes that participation of the Chief Executive Officer as a director, while keeping the roles of Chief Executive Officer and Chairman of the Board distinct, provides the proper balance between independence and management participation at this time. By having a separate Chairman of the Board, the Company maintains an independent

9

perspective on the Company’s business affairs, and at the same time, through the Chief Executive Officer’s participation as a director, the Board receives valuable experience regarding the Company’s business and maintains a strong link between management and the Board, which promotes clear communication, enhances strategic planning, and improves implementation of corporate strategies.

The independent directors who chair the Company’s Audit, Compensation, Nominating and Corporate Governance, and Strategy and Alternatives Committees also provide leadership to the Board in their assigned areas of responsibility. The Board believes that the independent governance of the Board is safeguarded through:

The Company will continue to review its Board structure to ensure that it is in the best position to deliver value to its shareholders, key stakeholders and the communities in which the Company operates.

2018 Amendments to Certificate of Incorporation and Bylaws

Following approval by the Company’s shareholders at the Company’s 2018 Annual Meeting of Shareholders, the Company amended its Certificate of Incorporation in March 2018, and made corresponding amendments to its Bylaws, to (i) declassify the Company’s Board of Directors and (ii) eliminate the supermajority voting requirements applicable to certain provisions of the Certificate of Incorporation. Declassification of the Company’s Board of Directors has been phased-in over a three-year period with all directors elected annually beginning with the 2021 Annual Meeting of Shareholders held on March 19, 2021. Each of the amendments are expected to provide increased director accountability and greater shareholder participation in the corporate governance of the Company.

Corporate Governance Guidelines

The Company’s Corporate Governance Guidelines, together with the Company’s Certificate of Incorporation, Amended and Restated Bylaws and the charters of the Board’s committees, provide the framework for the governance of the Company. The Corporate Governance Guidelines address, among other things, Board composition and operations, expectations of directors, succession planning, and communications to the Board. In September 2016, in connection with its annual review of the Company’s Corporate Governance Guidelines, the Board, following the recommendation of the Nominating and Corporate Governance Committee, approved several updates to memorialize its governance policies, including:

The full text of the Corporate Governance Guidelines is available by clicking on the Corporate Governance link included in the Investors tab of the Company’s website (www.emcore.com).

10

Code of Ethics

The Company has adopted a code of ethics entitled “EMCORE Corporation Code of Business Conduct and Ethics,” which is applicable to all employees, officers, and directors of the Company. In addition, the Company has adopted a Code of Ethics for Financial Professionals, which applies to the Chief Executive Officer, Chief Financial Officer, Vice Presidents of Finance, Controllers and Assistant Controllers of the Company. The full text of both the Code of Business Conduct and Ethics and the Code of Ethics for Financial Professionals is available by clicking on the Corporate Governance link in the Investors tab of the Company’s website (www.emcore.com). The Company intends to disclose any changes in or waivers from either of its codes of ethics for its directors and executive officers, to the extent disclosure is required by the applicable rules of the SEC and Nasdaq, by posting such information on its website at www.emcore.com or by filing a Current Report on Form 8-K.

Related Person Transaction Approval Policy

The Company’s Code of Business Conduct and Ethics sets forth the Company’s written policy for the review and approval of related person transactions. A related person is defined by applicable SEC rules as any executive officer, director or director nominee, any person who is known to be a beneficial owner of more than five percent (5%) of the voting securities of the Company, and any immediate family member of any of the foregoing persons.

A related person transaction is defined under applicable SEC rules as any financial or other transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) or any series of similar transactions, arrangements or relationships in which the Company (or a subsidiary) would be a participant and the amount involved would exceed $120,000, and in which any related person would have a direct or indirect material interest. A related person will not be deemed to have a direct or indirect material interest in a transaction if the interest arises only from the position of the person as a director of another corporation or organization that is a party to the transaction or the direct or indirect ownership by such person and all the related persons, in the aggregate, of less than ten percent (10%) of the equity interest in another person (other than a partnership) which is a party to the transaction. In addition, certain interests and transactions, such as director compensation that has been approved by the Board, transactions where the rates or charges are determined by competitive bid and compensatory arrangements solely related to employment with the Company (or a subsidiary) that have been approved by the Compensation Committee, are not subject to the policy.

The Board of Directors has delegated to the Audit Committee the responsibility for reviewing, approving and, where applicable, ratifying material related person transactions involving the Company’s directors or executive officers or their respective immediate family members or affiliated entities. If a member of the Audit Committee has an interest in a related person transaction, then he or she will not participate in the review process.

In considering the appropriate action to be taken regarding a related person transaction, the Audit Committee or the Board (as the case may be) will consider the best interests of the Company, whether the transaction is fair to the Company and serves a compelling business reason, and any other factors that it deems relevant. As a condition to approving or ratifying any related person transaction, the Audit Committee may impose whatever conditions and standards it deems appropriate, including periodic monitoring of ongoing transactions.

The Company’s Code of Business Conduct and Ethics also includes the Company’s Conflicts of Interest Policy, among other policies. The Conflicts of Interest Policy provides, among other things, that conflicts of interest exist where the interests or benefits of one person or entity conflict with the interests or benefits of the Company. The Code of Business Conduct and Ethics also provides restrictions on outside directorships, business interests and employment, and receipt of gifts and entertainment and requires that all material violations of the Company’s Code of Business Conduct and Ethics or matters involving financial or legal misconduct be reported to the Company’s Audit Committee on at least a quarterly basis, or more frequently depending upon the level of severity of the violation.

11

Directors and executive officers are also required to disclose potential and existing related person transactions on a quarterly basis and in Directors and Officers Questionnaires completed annually.

There are no related person transactions or conflicts of interest that have occurred since October 1, 2021.

Director Independence

The Board of Directors reviews the independence, and any possible conflicts of interest, of directors and director nominees at least annually. The Board of Directors has affirmatively determined that Messrs. Domenik, Grooms and Jackson and Ms. Heiks are independent under the listing standards applicable to the Company pursuant to the Nasdaq rules, comprising a supermajority (80%) of the Board. Mr. Rittichier, as the Company’s Chief Executive Officer, is not independent under the Nasdaq rules.

In addition to the Nasdaq listing standard rules, the Company’s Amended and Restated Bylaws require that a majority of the Board be independent pursuant to certain additional criteria that, in many cases, are not included within the requirements of the Nasdaq rules. For example, a director is not considered independent for purposes of the Amended and Restated Bylaws if, in the past three years, the director or any of his or her family members: (i) has received any remuneration as an advisor, consultant or legal advisor to the Company or any of its subsidiaries, affiliates, executive officers or to any other director of the Company; (ii) has an agreement with the Company or any of its subsidiaries or affiliates for personal services or has engaged in any transaction or business relationship with the Company or its subsidiaries or affiliates; or (iii) is affiliated with or employed by any present or former auditor for the Company. The Board of Directors has determined that each of Messrs. Domenik, Grooms and Jackson and Ms. Heiks are also independent directors within the meaning of the Company’s Amended and Restated Bylaws. A copy of the Company’s Amended and Restated Bylaws is posted in the Corporate Governance section on the Investors tab of the Company’s website (www.emcore.com).

In making its independence determination, the Board considers the responses of each director and executive officer to an annual Directors and Officers Questionnaire, in which each director answers specific questions to facilitate an evaluation of the director’s independence and each director and executive officer discloses, among other things, information about the following: his or her employment or other occupation; service on the boards or committees of other companies (both public and private); service as a director, trustee or executive officer in any charitable organizations; service of a family member as an officer in any company (public or private) or charitable organizations; relationships by blood, marriage or adoption among directors or executive officers of the Company; related person transactions with the Company; legal proceedings involving the Company; indebtedness to the Company; or prior arrangements and understandings with respect to the selection of directors or executive officers of the Company. Following a review of these Questionnaires, the Company did not identify any transactions, relationships or arrangements engaged in by these directors or in which they participated (directly or indirectly) to be considered by the Board of Directors in making its independence determination.

The Board of Directors’ Role in Risk Oversight

Risk is inherent in business. The Board of Directors recognizes the importance of effective risk oversight in running a successful business and in fulfilling its fiduciary responsibilities to the Company and its shareholders. While the Chief Executive Officer and other members of our senior leadership team are responsible for the day-to-day management of risk, the Board of Directors takes an active role in risk management and is responsible for (i) overseeing the Company’s aggregate risk profile, and (ii) assisting management in addressing specific risks, such as strategic and competitive risks, financial risks, brand and reputation risks, legal risks, regulatory risks, and operational risks.

The Board believes that its current leadership structure has facilitated its oversight of risk by combining independent leadership, through the separation of the roles of Chief Executive Officer and Chairman of the Board, independent Board committees, and majority independent Board composition. The Chairman of the

12

Board, independent committee chairs and members, and other directors are also experienced professionals or executives who can and do raise issues for Board consideration and review and who are willing to challenge management when necessary. The Board believes there has been a well-functioning and effective balance between the Chairman of the Board, non-management Board members, and the Chief Executive Officer, which enhances risk oversight.

The Board of Directors exercises its oversight responsibility for risk both directly and through its standing committees. Throughout the year, the Board and each committee spend a portion of their time reviewing and discussing specific risk topics. The full Board is kept informed of each committee’s risk oversight and related activities, and committee meeting minutes are available for review by all directors. Strategic, operational and competitive risks also are presented and discussed at the Board’s quarterly meetings, and more often as necessary. On at least an annual basis, the Board reviews our long-term strategic plans. In addition, at least quarterly, or more often as necessary, the Board receives a briefing on material legal and regulatory matters.

The Audit Committee is responsible for reviewing our major financial risk exposures, financial reporting, internal controls, credit and liquidity risk, compliance risk, key operational risks, related party transactions, and other potential conflicts of interest. The Audit Committee meets periodically in separate executive session with the Chief Financial Officer and the independent auditor, as well as with committee members only, to facilitate a full and candid discussion of risk and other issues. The Audit Committee is also responsible for overseeing the Company’s cybersecurity policies and procedures. The Company maintains an information security training and compliance program and an information security risk insurance policy, and we are compliant with DFARS 252.204-7012 and DFARS 252.204-7020 and have a compliant NIST SP 800-171 self-assessment status. The Company has not experienced any information security breaches and has not incurred any net expenses from information security breaches in the last three years.

The Compensation Committee is responsible for overseeing human capital and compensation risks, including evaluating and assessing risks arising from our compensation policies and practices for all employees and ensuring executive compensation is aligned with performance. The Compensation Committee also is charged with monitoring our incentive and equity-based compensation plans, including employee retirement and benefit plans. In addition, the Compensation Committee is responsible for overseeing risks associated with succession planning for the Board.

The Nominating and Corporate Governance Committee oversees risks related to our overall corporate governance, including Board and committee composition, Board size and structure, and director independence.

The Strategy and Alternatives Committee oversees risks related to the Company’s strategic opportunities and alternatives which may be relevant to the Company’s business.

In addition to the responsibilities undertaken by the committees discussed above, the Board committees may have oversight of specific risk areas consistent with the committees’ charters and responsibilities.

Board Meetings and Attendance

The Board of Directors held sixteen (16) regularly scheduled and special meetings during fiscal 2022. During fiscal 2022, all directors of the Company attended at least seventy-five percent (75%) of the aggregate meetings of the Board and committees on which they served during their tenure on the Board.

Board Committees

Audit Committee

The Company has a separately-designated standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Mr. Jackson

13

(chairman), Mr. Domenik and Ms. Heiks currently serve as members of the Audit Committee. Each member of the Audit Committee is an independent director within the meaning of applicable Nasdaq and SEC rules. The Board of Directors has determined that Mr. Jackson is an audit committee financial expert within the meaning of SEC rules.

The Audit Committee is responsible for, among other things: (i) reviewing the financial information that will be provided to the Company’s shareholders and overseeing the accounting and financial reporting processes of the Company performed by management, the audits of the financial statements of the Company and the Company’s systems of internal controls; (ii) the appointment, compensation, retention and oversight of the work of the Company’s independent registered public accounting firm, including reviewing its independence, qualifications and performance; (iii) overseeing the internal audit function of the Company; and (iv) reviewing compliance by the Company with legal and regulatory requirements. The Audit Committee is also responsible for overseeing the Company’s cybersecurity policies and procedures.

A copy of the Charter of the Audit Committee is posted in the Corporate Governance section on the Investors tab of the Company’s website (www.emcore.com). The Audit Committee met eight (8) times during fiscal 2022.

Compensation Committee

The Compensation Committee evaluates the performance of the Chief Executive Officer and other executive officers and reviews and approves their compensation. Messrs. Jackson (chairman), Domenik and Grooms currently serve as members of the Compensation Committee. Each member of the Compensation Committee is an independent director within the meaning of applicable Nasdaq and SEC rules. The processes and procedures for the review and approval of executive compensation are described in the Compensation Discussion and Analysis section of this Proxy Statement. In addition, the Compensation Committee has responsibility for recommending to the Board the level and form of compensation and benefits for directors. It also administers the Company’s incentive compensation plans and is responsible for setting the compensation and benefits for the Company’s executives. Additionally, the Compensation Committee is responsible for executive officer development and retention and corporate succession plans for the Chief Executive Officer. A copy of the Charter of the Compensation Committee is posted in the Corporate Governance section on the Investors tab of the Company’s website (www.emcore.com). The Compensation Committee met five (5) times during fiscal 2022.

To the extent consistent with its obligations and responsibilities, the Compensation Committee may form subcommittees of one or more members of the Compensation Committee and delegate its authority to the subcommittees as it deems appropriate. The Compensation Committee has the authority to retain and terminate external advisors in connection with the discharge of its duties.

During fiscal 2022, the Compensation Committee engaged Compensia, Inc. (“Compensia”), an independent compensation consultant, to conduct a review of the Company’s peer group of companies (the “Peer Group”) and conduct a compensation survey of executive compensation and Board of Directors’ compensation utilizing the Peer Group. For more information regarding the services provided by Compensia, see the “Compensation Discussion and Analysis — Role of Compensation Consultant” section of this Proxy Statement. The Compensation Committee has assessed the independence of Compensia and concluded that its engagement of Compensia does not raise any conflict of interest with the Company or any of its directors or executive officers.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee identifies and recommends new members to the Company’s Board of Directors and has responsibility for certain corporate governance matters. Mr. Domenik (chairman) and Mr. Grooms currently serve as members of the Nominating and Corporate Governance Committee. A copy of the Charter of the Nominating and Corporate Governance Committee is posted in the Corporate Governance section on the Investors tab of the Company’s website (www.emcore.com). The Nominating and Corporate Governance Committee met four (4) times during fiscal 2022.

14

In performing its responsibilities relating to the identification and recommendation of new directors, the Nominating and Corporate Governance Committee has not established specific minimum age, education, experience or skill requirements for potential director nominees. When considering a potential director candidate, the Nominating and Corporate Governance Committee considers the candidate’s individual skills and knowledge, including experience in business, finance, or administration, familiarity with national and international business matters, and appreciation of the relationship of the Company’s business to changing needs in our society. The Nominating and Corporate Governance Committee also carefully considers any potential conflicts of interest. All nominees must possess demonstrated character, good judgment, integrity, relevant business, functional and industry experience, and a high degree of acumen. Although the Nominating and Corporate Governance Committee does not have a formal policy with respect to diversity in identifying nominees for director, the Nominating and Corporate Governance Committee recognizes the benefits associated with a diverse board and considers diversity as a factor when identifying and evaluating candidates for membership on our Board, including in connection with its efforts to seek additional female candidates and candidates from unrepresented communities that it believes have the requisite qualifications and experience to join the Board. The Nominating and Corporate Governance Committee utilizes a broad conception of diversity, including professional and educational background, prior experience on other boards of directors (both public and private), political and social perspectives as well as race, gender and national origin. Utilizing these factors, and the factors described above, the Nominating and Corporate Governance Committee makes recommendations, as it deems appropriate, regarding the composition and size of the Board. The priorities and emphasis of the Nominating and Corporate Governance Committee and of the Board may change from time to time to take into account changes in business and other trends and the portfolio of skills and experience of current and prospective Board members.

The Nominating and Corporate Governance Committee identifies potential candidates from a number of sources, including current members of the Board and, if the Nominating and Corporate Governance Committee so chooses, third party search firms. The Nominating and Corporate Governance Committee may also consider candidates proposed by management or by shareholders. After the Nominating and Corporate Governance Committee’s initial evaluation of a candidate, if that candidate is still of interest to the Nominating and Corporate Governance Committee, one or more designated members of the Board will interview the candidate. Additional interviews by other Board members and/or senior management may take place and other screening processes may be undertaken. The Nominating and Corporate Governance Committee will meet to finalize its recommended candidates, which will be submitted to the entire Board for consideration. All candidates who are recommended by the Nominating and Corporate Governance Committee and approved by the Board are then included as nominees in the first proxy statement following their appointment or nomination and each year thereafter.

The Nominating and Corporate Governance Committee will consider suggestions from shareholders regarding possible director candidates for election at future annual meetings of shareholders or in the event of a vacancy on the Board of Directors. The Nominating and Corporate Governance Committee evaluates director candidates recommended by shareholders in the same way that it evaluates candidates recommended by other sources as described above. Such suggestions must contain (1) all information for each nominee required to be disclosed in a proxy statement for the election of directors pursuant to applicable rules of the SEC, (2) the name and address of the shareholder making the recommendation, the number of shares of Common Stock beneficially owned by the shareholder as of the date the shareholder gives notice and the length of ownership, (3) the name, age and address of the director candidate and a description of the director candidate’s business experience for at least the previous five years, (4) the number of shares of Common Stock beneficially owned by the director candidate, and (5) the written consent of the director candidate to serve as a director if elected. The Nominating and Corporate Governance Committee may require additional information as it deems reasonably necessary to determine the eligibility of the director candidate to serve as a member of our Board of Directors. To be considered for possible nomination by the Board at the next annual meeting of shareholders, such suggestions must be submitted to the Company’s Secretary no later than September 30 prior to the next annual meeting of shareholders (i.e., September 30, 2023 for the Company’s 2024 Annual Meeting of Shareholders). Shareholders who wish to nominate a person for election as a director at a meeting of shareholders (as opposed to making a

15

recommendation to the Nominating and Corporate Governance Committee as described above) must deliver written notice to the Company’s Secretary in accordance with the procedures and timing set forth in the Company’s Amended and Restated Bylaws, as discussed in the section of this Proxy Statement entitled “General Matters — Shareholder Proposals” below.

The Nominating and Corporate Governance Committee is also responsible for certain corporate governance matters, including:

When appropriate, the Nominating and Corporate Governance Committee may form subcommittees of one or more of its members and delegate its authority to these subcommittees as it deems appropriate.

Strategy and Alternatives Committee

The purpose of the Strategy and Alternatives Committee is to oversee the Company’s strategic plan, working with management to define and set strategic goals and expectations for the Company, to evaluate strategic opportunities and alternatives available to the Company, including potential mergers, acquisitions, divestitures and other key strategic transactions outside the ordinary course of the Company’s business, and to perform any other activities or responsibilities as may be delegated to the Strategy and Alternatives Committee from time to time by the Board. Mr. Domenik (chairman), Ms. Heiks and Mr. Jackson currently serve as members of the Strategy and Alternatives Committee. A copy of the Charter of the Strategy and Alternatives Committee is posted in the Corporate Governance section of the Investors tab of the Company’s website (www.emcore.com).

Board Attendance at Annual Meetings

The Company requires members of the Board of Directors to attend the Company’s Annual Meetings of Shareholders, absent extraordinary circumstances. All of the then-current members of the Board of Directors attended the 2022 Annual Meeting of Shareholders.

Annual Board Evaluations

Pursuant to our Corporate Governance Guidelines and the charter of the Nominating and Corporate Governance Committee, the Nominating and Corporate Governance Committee oversees an annual evaluation of the performance of the Board and each committee of the Board. The evaluation process is facilitated by outside legal counsel and is designed to assess the overall effectiveness of the Board and its committees and to identify opportunities for improving Board and Board committee operations and procedures. The annual evaluations are generally conducted in the first quarter of each calendar year and the results of the annual evaluation are reviewed and discussed by the Board.

Management Succession Planning

The Compensation Committee is responsible for reviewing the Company’s succession plan for the Chief Executive Officer and general management. In performing these functions, the Compensation Committee, with

16

the assistance of the Chief Executive Officer, periodically assesses senior managers and their succession potential.

Shareholder Communications with the Board

Shareholders may communicate with the Company’s Board of Directors through its Secretary by writing to the following address: Board of Directors, c/o The Secretary, EMCORE Corporation, 2015 W. Chestnut Street, Alhambra, CA, 91803. The Company’s Secretary will forward all correspondence to the Board of Directors, except for junk mail, mass mailings, product complaints or inquiries, job inquiries, surveys, business solicitations or advertisements, or patently offensive or otherwise inappropriate or redundant material. A Board member may request to see all shareholder communications at any time.

DIRECTOR COMPENSATION FOR FISCAL YEAR 2022

The Company compensates each non-employee director for service on the Board of Directors. The following table presents director compensation information for fiscal 2022 for the Company’s non-employee directors who served during any part of fiscal 2022.

17

With respect to the fees earned or paid in cash as reflected in the table above, fees were earned and paid on the following basis:

Director Compensation Policy

During fiscal 2022, the Company’s Director Compensation Policy (the “Director Compensation Policy”) entitled each director to the following compensation for their service as a member of the Board:

Under the Director Compensation Policy, the equity awards referenced above are granted, every three years, in the form of restricted stock units immediately following the Company’s annual meeting of shareholders to each director then in office, in a number of restricted stock units equal to $225,000 (or $352,500 in the case of the grant made to the Chairperson), divided by the per-share closing price of the Common Stock on the date of such annual meeting. The restricted stock units will vest as to one third of the shares underlying the award on each of the first three anniversaries of the grant date (or, if the Company’s corresponding annual meeting of shareholders occurs prior to such vesting date, on the day prior to that annual meeting), subject to the non-employee director’s continued service on the Board through such vesting date. In the event a non-employee director or Chairman joins the Board on a date other than the date of an annual meeting of the Company’s shareholders, the equity

18

compensation is prorated based on the number of calendar months that have elapsed since the most recent annual meeting in which 3-Year equity awards were granted. Unvested equity awards will also vest in full upon a director’s earlier termination of service due to death or disability or upon a change of control of the Company.

Cash retainers are paid quarterly in arrears. If a non-employee director serves in the corresponding position for only a portion of the year, the cash retainers will be pro-rated (with the proration based on the number of calendar days in the quarter that the director served as a non-employee director or held the particular position, as the case may be). Any time that the Company’s trading window is open under the Company’s Executive Insider Trading Policy, a non-employee director may elect that all or a portion of his or her cash retainer be converted into fully vested shares of the Common Stock in a number of shares determined by dividing (i) the amount of the cash retainer for the applicable quarter by (ii) the per-share closing price of the Common Stock on the last trading day of the applicable quarter, with the result rounded down to the nearest whole share. Any such shares issued pursuant to such an election shall be issued under, and subject to the terms of, the 2019 Equity Incentive Plan or any other equity compensation plan approved by the Company’s shareholders and in effect at the time of grant.

In accordance with the Director Compensation Policy, on March 19, 2021, each non-employee director serving on the Board as of such date (other than Mr. Domenik) was granted 33,632 restricted stock units (calculated by dividing (a) the $225,000 3-Year Equity Award to which each director is entitled under the Director Compensation Policy by (b) $6.69, which was the closing share price of the Common Stock on March 19, 2021, rounded down to the nearest whole share) for services rendered from the period of March 19, 2021 through March 19, 2024 (or, if the Company’s 2024 Annual Meeting of Shareholders occurs prior to such date, on the day prior to the 2024 Annual Meeting of Shareholders). Pursuant to the Director Compensation Policy, Mr. Domenik received 52,690 restricted stock units for his service as Chairman of the Board (calculated by (a) adding the $225,000 3-Year Equity Award to which each director is entitled under the Director Compensation Policy plus the $127,500 3-Year Equity Award to which the Chairman is entitled under the Director Compensation Policy, then (b) dividing by the $6.69 closing share price of the Common Stock on March 19, 2021. In all cases, these shares were granted under the 2019 Equity Incentive Plan. Pursuant to the Director Compensation Policy, all future director equity awards will be made under the 2019 Equity Incentive Plan or any other equity compensation plan approved by the Company’s shareholders and in effect at the time of grant. In accordance with the Director Compensation Policy, the next equity grants to current Board members are expected to occur in March 2024.

No director who is also an employee of the Company receives compensation for services rendered as a director.

Director Stock Ownership and Holding Requirements.

Our Board of Directors has a stock ownership policy for directors and executive officers. We believe that this policy aligns the interests of our directors with those of our shareholders by requiring directors to have direct ownership in shares of our Common Stock. The policy requires each of our non-employee directors to own shares of our Common Stock having a value equal to at least three times the annual cash retainer they receive (excluding retainers for committee members and chairpersons). Each director is required to be in compliance with the required minimum ownership levels within five years from the date such person is appointed as a director, and is required to retain at least fifty percent (50%) of the net after-tax shares received in respect of equity awards until he or she is in compliance.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis describes the material elements of the Company’s executive compensation program and analyzes the compensation decisions made for the executive officers included in the Summary Compensation Table (the “Named Executive Officers”) for the fiscal year ended September 30, 2022 (“fiscal 2022”).

2022 Named Executive Officers

Our Named Executive Officers for fiscal 2022 were:

Jeffrey Rittichier — Chief Executive Officer (our “CEO”)

Tom Minichiello — Chief Financial Officer (our “CFO”)

Albert Lu — our former SVP and GM, Aerospace and Defense    

Because we qualify as a “smaller reporting company”, we have only three Named Executive Officers for fiscal 2022.

Fiscal 2022 Financial Performance

Our significant transformation that began in the fiscal year ended September 30, 2019 (“fiscal 2019”) continued throughout fiscal 2022. Five years ago, the Company’s Cable TV (“CATV”) transmitters and components product lines represented over 90% of our total revenue and carried 90% of our assets and costs. Due to risks related to this revenue concentration, including uncertainties concerning changing technology adoption in the CATV market, we initiated efforts to diversify our revenue stream. These efforts accelerated during fiscal 2022. Several key actions that accelerated this transformation were the subject of significant activity throughout Fiscal 2022, including the acquisitions of (i) the Space & Navigation business of L3Harris Technologies, Inc. (“L3Harris”) on April 29, 2022 and (ii) the Inertial Navigation business of KVH Industries, Inc. (“KVH”) on August 9, 2022. As a result of these efforts to diversify our revenue stream, the contribution of our CATV transmitters and components product lines to our total revenue declined to approximately 8% during the quarter ended September 30, 2022, while at the contribution of our Aerospace and Defense business to our total revenue increased to 82% during the quarter ended September 30, 2022.

We believe the actions initiated by the Company to transform our business that continued in fiscal 2022 position the Company for long-term growth and are reflected in these significant changes in our revenue mix.

Executive Compensation Program Highlights

Highlights of our executive compensation program include:

20

Objectives of the Company’s Executive Compensation Program

The Company’s executive compensation program is designed to:

Listening to Our Shareholders

Each year, we provide our shareholders the opportunity to cast an advisory vote on our executive compensation program. This annual vote is known as the “say-on-pay” proposal. At the Company’s 2022 Annual Meeting of Shareholders held on March 11, 2022, approximately 94.0% of the votes cast on the say-on-pay proposal were voted in favor of the proposal. This say-on-pay result continued the strong support demonstrated by our say-on-pay votes for the five previous fiscal years, where over 90% of shareholders voted in favor of our say-on-pay proposal for four of such fiscal years and 86.7% of the shareholders voted in favor of our say-on-pay proposal for fiscal the fiscal yead ended September 30, 2021 (“fiscal 2021”). The Compensation Committee believes this high degree of support for our say-on-pay proposals in the past five years reflects shareholders’ approval of the significant changes we made to our executive compensation program during the fiscal year ended September 30, 2016 (“fiscal 2016”) and that have been maintained through fiscal 2022.

21

We have continued to meet with a significant portion of our institutional shareholders who each individually hold more than 0.5% of our outstanding shares. In general, our shareholders have continued to react positively to our executive compensation and corporate governance practices. Our executive compensation programs have strong governance components that further strengthen our pay-for-performance compensation philosophy, including the following:

				Compensation Practice				Our Policies and Actions
		✓		Independent Compensation Committee				Our Compensation Committee consists entirely of independent directors.
		✓		Independent Compensation Consultant				Our Compensation Committee utilizes an independent compensation consultant, which is retained directly by the Compensation Committee and provides no other services to the Company’s management.
		✓		Pay for Performance: Short-Term Incentive Plan				Continued with our performance-based annual incentive program design. 100% of each Named Executive Officer’s cash bonus payment for fiscal 2022 was tied to Company performance metrics for fiscal 2022, and no payments were made to any of our Named Executive Officers under our short-term incentive plan due to the Company’s financial performance during fiscal 2022.
		✓		Pay for Performance – Equity Awards				In fiscal 2022, 100% of the target number of shares subject to equity awards granted to our Named Executive Officers consisted of PSUs that will vest, if at all, based on our relative total shareholder return over a three-year performance period. No time-based restricted stock units were granted to the Named Executive Officers in fiscal 2022.
		✓		Minimum Vesting Period for Equity Awards				At the 2019 Annual Meeting of Shareholders, the Company’s shareholders, upon the recommendation of the Board, approved the Company’s 2019 Equity Incentive Plan, which requires substantially all awards granted under the 2019 Equity Incentive Plan to have a minimum vesting period of one year and, subject to the Compensation Committee’s discretion to accelerate awards, prohibits any portion of an award to vest earlier than the first anniversary of the grant date of the award.
		✓		Limited Discretion to Accelerate Vesting on Change in Control				As further described in “Proposal II: Amendment to the 2019 Equity Incentive Plan,” subject to shareholder approval, our Compensation Committee has amended the Company’s 2019 Equity Incentive Plan to

22

								provide greater specificity on how awards vest in connection with a change of control (as defined in the 2019 Equity Incentive Plan) and to limit the Compensation Committee’s discretion to accelerate awards upon the consummation of a change in control.
		✓		Clawback Policy				Maintain a clawback policy that applies to all of the Named Executive Officers.
		✓		Stock Ownership Policy				Maintain a stock ownership policy with a 3x salary ownership requirement for our Chief Executive Officer and a 1x salary ownership requirement for other Named Executive Officers. Executive officers are required to retain at least 50% of the net after-tax shares received in respect of equity awards until they are in compliance.
		✓		Restrictions on Hedging and Pledging Transactions				Maintain a policy prohibiting pledging or hedging of the Company’s securities or engaging in derivative transactions related to the Company’s common stock.

Role of the Compensation Committee

Pursuant to its charter, the Compensation Committee has the authority to determine the compensation of our Named Executive Officers. The Compensation Committee approves the structure of our executive compensation program, and is responsible for administering our equity compensation plans, including approving grants of awards under the plans. In performing its duties, the Compensation Committee is authorized to consider the recommendations of our Chief Executive Officer when determining the compensation of the other Named Executive Officers.

The elements of our executive compensation program and the compensation amounts payable thereunder to each Named Executive Officer were approved by the Compensation Committee. All Compensation Committee members are independent under applicable Nasdaq rules, and, except for recommendations made by Mr. Rittichier with respect to the compensation of the other Named Executive Officers (other than himself), no Named Executive Officers had any role in determining the compensation of the Named Executive Officers.

Compensation Risk

The Compensation Committee has reviewed the Company’s compensation policies and practices for all employees, including executive and non-executive officers, and determined that the Company’s compensation programs do not give rise to risks reasonably likely to have a material adverse effect on the Company. The Compensation Committee noted several design features of the Company’s cash and equity incentive programs for executive officers in particular that reduce the likelihood of excessive risk-taking and instead encourage behaviors that support sustainable value creation by rewarding employees for achieving long-term financial and strategic objectives through prudent business judgment and appropriate risk taking. Some of these elements include:

23

Role of Compensation Consultant

Pursuant to its charter, the Compensation Committee has the authority to engage its own advisors to assist in carrying out its responsibilities. Since fiscal 2016, the Compensation Committee has retained Compensia, a national compensation consulting firm, to advise it regarding the amount and types of compensation that we provide to our Named Executive Officers and how our compensation practices compare to the compensation practices of other companies. The members of the Compensation Committee considered input from Compensia as one factor in making decisions with respect to executive compensation matters, along with information and analysis they received from management and their own judgment and experience.

The Compensation Committee regularly reviews the services provided by Compensia and performs an assessment at least annually on the independence of Compensia to determine whether the compensation consultant is independent. The Compensation Committee determined that Compensia is independent in providing the Compensation Committee with executive compensation consulting services and that Compensia’s work for the Compensation Committee did not raise any conflicts of interest, consistent with SEC rules and Nasdaq listing standards. Compensia did not perform any services for the Company during fiscal 2022 other than providing advice with respect to executive officer and director compensation.

In October 2021, the Compensation Committee engaged Compensia to conduct a review of the Company’s peer group of companies, as well as a comprehensive compensation survey utilizing the new peer group for each of

24

our Named Executive Officers. Our methodology for selecting our new 2021 peer group of companies, based on the recommendation of Compensia, was to (1) start with our existing peer group, (2) screen out any companies that had been acquired, (3) perform a revenue screen of the existing peer group and other publicly traded Electronic Component, Communication Equipment and Aerospace & Defense companies with revenues over the last four quarters that were approximately 0.5x to 2.5x the Company’s revenues over the same four quarters, (4) perform a market capitalization screen of the existing peer group and other publicly traded Electronic Component, Communication Equipment and Aerospace & Defense companies with 30-day average market capitalizations as of the beginning of September 2021 that were approximately 0.25x to 4x the Company’s 30-day average market capitalization over the same period, and (5) review the peer group of companies used in the prior year by certain proxy advisory firms for potential inclusion as peer group companies if they satisfied the revenue and market capitalization screens described above.

Based on this methodology, we implemented the following changes to our peer group:

In October 2021, in connection with compensation decisions related to fiscal 2022, Compensia reviewed the compensation levels for each of the Named Executive Officers, utilizing the Company’s new October 2021 peer group with respect to each of Mr. Rittichier and Mr. Minichiello, and a broad group of technology companies from Compensia’s database with respect to Mr. Lu. The analysis covered base salary, target bonus as a percent of salary, target total cash compensation, total long-term incentive compensation value and target total direct compensation relative to each company in the October 2021 peer group (or the broad group of companies with respect to Mr. Lu).

To keep compensation competitive, the Compensation Committee made a determination in March 2022 to (1) increase Mr. Rittichier’s base salary from $475,000 to $500,000 and his target bonus opportunity from 90% of his base salary to 100% of his base salary, each effective as of March 2022, (2) maintain Mr. Minichiello’s base salary of $365,000 and increase his target bonus opportunity from 50% of his base salary to 75% of his base salary and (3) maintain Mr. Lu’s base salary of $310,000 and his target bonus opportunity of 60% of his base salary.

25

The purpose of the compensation review was to provide the Compensation Committee with information on the compensation practices and program designs at peer companies. This information is used by the Compensation Committee to inform its decision-making process with respect to the compensation amounts for the Named Executive Officers. However, the Compensation Committee does not rigidly adhere to a benchmarking strategy in setting compensation amounts for the Named Executive Officers. Instead, the peer group compensation information is used as one of the data points for the Compensation Committee to make subjective compensation decisions using its business judgment after considering a number of factors, including our objectives of attracting and motivating highly qualified executives, holding executives accountable and rewarding them for individual performance, and ensuring that compensation levels are externally competitive and internally equitable.

Base Salary

Base salaries for the Named Executive Officers are determined based upon job responsibilities, level of experience, individual performance, and the peer group compensation information described above. No Named Executive Officers are entitled to any automatic base salary increases, and all base salary increases are determined by the Compensation Committee in its discretion. The Compensation Committee reviews any proposed base salary increase for our Chief Executive Officer in executive session without Company management present.

As described above, in March 2022, the Compensation Committee reviewed each Named Executive Officer’s base salary and determined to increase Mr. Rittichier’s base salary from $475,000 to $500,000, maintain Mr. Minichiello’s base salary at $365,000 and maintain Mr. Lu’s base salary at $310,000.

Short-Term Cash Incentives

In General. Historically, the Company established a new cash incentive plan each fiscal year which provided the Company’s executive officers an opportunity to receive an annual cash payment in addition to their base salaries. In place of an annual plan, on June 9, 2022, the Company’s Compensation Committee approved the EMCORE Corporation Short-Term Incentive Plan (the “Short-Term Incentive Plan”). The Short-Term Incentive Plan provides participants with an opportunity to earn cash bonus payments upon the satisfaction of performance goals for a specified performance period, generally the Company’s fiscal year, and generally subject to continued employment through the payment date.

Pursuant to the terms of the Short-Term Incentive Plan, the Compensation Committee has the discretionary authority to (1) select eligible employees for participation in the Short-Term Incentive Plan; (2) establish performance periods, target bonus amounts and performance goals; (3) determine the amount of any bonuses payable under the Short-Term Incentive Plan; and (4) delegate certain duties to the Company’s Chief Executive Officer. Individuals eligible for awards under the Short-Term Incentive Plan are employees of the Company, as determined by the Compensation Committee, which include the Company’s executive officers.

Under the Short-Term Incentive Plan, bonus payments, if any, are based on an individual target bonus amount for the performance period set by the Compensation Committee and are directly related to the satisfaction of the applicable performance goal(s) set by the Compensation Committee for such performance period. Performance goals may include one or more of the enumerated benchmarks set forth in the Short-Term Incentive Plan or such other criteria as determined by the Compensation Committee. Such performance goals may relate to the performance of the Company as a whole, a business unit, division, department, individual or any combination of these and may be applied on an absolute basis and/or relative to one or more peer group companies or indices, or any combination thereof, as determined by the Compensation Committee. The Plan provides that the maximum bonus payable to any participant for any fiscal year is 150% of the applicable participant’s base salary for such period or such lower amount as determined by the Compensation Committee. Any bonus payments earned under the Short-Term Incentive Plan will be paid as soon as administratively practicable after the end of the applicable performance period.

26

The Short-Term Incentive Plan contains baseline good governance features – bonus payments are tied to performance metrics and are subject to a hardwired cap rather than a cap determined year (and the 2022 annual bonus cap was less than the overall cap under the plan). The Short-Term Incentive Plan shall remain in effect until such time as the Compensation Committee or the Board of Directors of the Company suspends, modifies or terminates the Short-Term Incentive Plan.

Fiscal 2022 Target Bonus Amounts and Performance Goals. With respect to each of the Named Executive Officers, the target bonus amount for each of the Company’s executive officers under the Short-Term Incentive Plan for fiscal 2022 was less than the target bonus opportunity previously approved by the Compensation Committee for such executive officer. The fiscal 2022 target bonus opportunities under the Short-Term Incentive Plan were as follows: 50% of Mr. Rittichier’s base salary, 37.5% of Mr. Minichiello’s base salary and 30% of Mr. Lu’s base salary. The fiscal 2022 performance goals for the Named Executive Officers related solely to the performance of the Company – 37.5% based on the Company’s achievement of a bookings target for its Broadband segment during the period of April 1, 2022 through September 30, 2022, 37.5% based on the Company’s achievement of a bookings target for its Aerospace & Defense segment during the period of April 1, 2022 through September 30, 2022, 12.5% based on the Company’s achievement of a Non-GAAP operating profit target for its Aerospace & Defense segment during fiscal 2022 and 12.5% based on the Company’s achievement of a Non-GAAP operating profit target for its Broadband segment during fiscal 2022. The amount of cash bonus payable to each Named Executive Officer under the Short-Term Incentive Plan with respect to the fiscal 2022 could range from 0% to 120% of the Named Executive Officer’s target bonus opportunity, as illustrated by the table below.

The Compensation Committee determined to cap bonus payouts for outperformance at 130% of the target bonus amount to limit our executives’ maximum bonus potential for fiscal 2022. In addition, the Compensation Committee established a threshold of 80% of each target metric for any cash bonus to be paid to our Named Executive Officers corresponding to such target.

The Compensation Committee established Broadband segment and Aerospace Defense segment non-GAAP operating profit for fiscal 2022 as the Company performance goal because it believes this financial metric was the best indicator of the Company’s performance for fiscal 2022, and established Broadband segment and Aerospace Defense segment bookings, in each case during the period of April 1, 2022 through September 30, 2022, because it believed these metrics properly incentivized the Company’s management to achieve objectives that would support the Company’s new structure and strategies (following its acquisition of the Space & Navigation business of L3Harris and the Inertial Navigation business of KVH) during fiscal 2022, fiscal 2023 and beyond. For purposes of awards payable under the Short-Term Incentive Plan with respect to fiscal 2022, “non-GAAP operating profit” means the applicable segment’s operating profit as determined under generally accepted accounting principles in the United States, with adjustments approved by the Compensation Committee that are consistent with the description included in the Corporation’s quarterly earnings news releases under the section “Use of Non-GAAP Financial Measures” and the associated reconciliation schedules included in both the Corporation’s quarterly earnings news releases and in the quarterly Board of Director meetings and Audit Committee calls. The adjusted items included in these reconciliations generally include stock-based compensation expense; acquisition-related items including expenses incurred by or on behalf of the Strategy and Alternatives Committee of the Board of Directors, including in connection with proposed acquisitions or divestitures; restructuring, severance/separation, and transition charges; litigation expenses associated with any material arbitration or litigation matters; gain or loss on the sale of assets; and other non-recurring operating net

27

gains or losses and any other items consistent with the description included in the Corporation’s quarterly earnings news releases under the section “Use of Non-GAAP Financial Measures.”

The Compensation Committee established a bookings target for its Aerospace & Defense segment during the period of April 1, 2022 through September 30, 2022 of $37.6 million, a bookings target for its Broadband segment during the period of April 1, 2022 through September 30, 2022 of $10.0 million, a Non-GAAP operating profit target for its Aerospace & Defense segment fiscal 2022 of $(18.105) million and a Non-GAAP operating profit target for Broadband segment for fiscal 2022 of $12.993 million. The Company’s actual bookings for its Aerospace & Defense segment during the period of April 1, 2022 through September 30, 2022 were $39.1 million, its actual bookings for its Broadband segment during the period of April 1, 2022 through September 30, 2022 were $4.7 million, and its actual Non-GAAP operating profit for its Aerospace & Defense segment during fiscal 2022 was $(22.69) million and its actual Non-GAAP operating profit for its Broadband segment during fiscal 2022 was $12.41 million. Non-GAAP bookings are reconciled in accordance with GAAP and included in the Company’s Annual Report on Form 10-K filed with the SEC on December 28, 2022. While the Company exceeded the target Aerospace & Defense bookings, in light of the Company’s overall financial performance in fiscal 2022 and the Company’s cash balance as of the end of fiscal 2022, the Compensation Committee determined in December 2022 that each Named Executive Officer would not receive any cash bonus under the Short-Term Incentive Plan for fiscal 2022.

Long-Term Stock-Based Incentives

In General. The Company believes that stock-based incentives are an effective means for aligning the interests of our executives with the interests of our shareholders and that the long-term compensation of the Company’s Named Executive Officers should be linked to the value provided to our shareholders. In addition, we use stock-based compensation as a retention tool. Because our stock-based awards generally vest over a multi-year period, they provide our executives with an ongoing incentive to continue their employment with the Company and to maximize shareholder value. Long-term stock-based incentives granted to our executives for the last several years have been structured in the form of restricted stock unit awards. Restricted stock unit awards are designed to link executives’ interests with those of the Company’s shareholders, because the value of the awards is based on the value of our Common Stock. In addition, they provide a long-term retention incentive throughout the vesting period because the restricted stock units generally have value regardless of stock price volatility.

In granting equity awards to our Named Executive Officers, the Compensation Committee used its judgment and discretion to determine the appropriate value of each award at the time it was granted (based on the value of our Common Stock when granted) and reviewed each executive’s individual performance and the performance of the Company in the prior fiscal year, as well as the peer group compensation information described above. For the Named Executive Officers, at least 50% of the target number of shares subject to the restricted stock unit awards have consisted of PSUs that will vest based on our relative total shareholder return over a three-year performance period, and with respect to equity awards granted to our Named Executive Officers in fiscal 2022, 100% of the shares subject to the awards consisted of PSUs that will vest based on our relative total shareholder return over a three-year performance period, in each case, generally subject to the executive’s continued employment through the vesting date.

Fiscal 2022 Awards for Named Executive Officers. In March 2022, the Compensation Committee determined to grant PSU awards (as described below) to each of Mr. Rittichier, Mr. Minichiello and Mr. Lu convertible into a target number of shares of the Company’s common stock equal to 405,405, 162,262 and 135,135 shares, respectively, and that vest based on a performance period ending in March 2025, in each case, generally subject to the executive’s continued employment through the vesting date. The Compensation Committee believes that granting 100% of Mr. Rittichier’s, Mr. Minichiello’s and Mr. Lu’s equity-based compensation for fiscal 2022 in the form of PSU awards further serves to align shareholder interests with the interests of the Named Executive Officers and serves as an effective balance between retention and performance, risk and leverage, and alignment with our peers. In determining the appropriate value of these awards, the Compensation Committee used its

28

judgment and discretion, and considered the size of historical equity award grants made to other senior executives, the recommendations of Compensia, and the peer group compensation information described above.

Fiscal 2022 Performance-Based Program Design. The PSUs will vest based on a combination of our relative total shareholder return over a three-year performance period, generally subject to the executive’s continued employment through the vesting date. We chose relative total shareholder return as the applicable performance measure because (1) we believe it will incentivize the Named Executive Officers to focus on and grow our returns for shareholders, and (2) it is an objective and easily understandable performance metric that is different than the non-GAAP operating profit-based and bookings-based performance measures used with respect to cash bonus payable for fiscal 2022 under the Short-Term Incentive Plan (and the net cash balance and earnings-based performance measures used under certain of our previous annual cash incentive programs).

Relative total shareholder return with respect to the grants of PSUs made in fiscal 2022 is measured against the companies in the Russell 2000 Index. We previously measured our performance against the Russell Microcap Index because we wanted to measure our performance against a broad index of similarly sized companies in which investors may choose to invest and measure our performance against. Since we were added to the Russell 2000 Index in June 2021, we chose to measure our performance against the Russell 2000 Index for purposes of the grants of PSUs made in fiscal 2022. Measuring our performance against the Russell 2000 Index allows us to measure our performance against a broad index of relatively similarly sized companies in which investors may choose to invest and measure performance against, instead of measuring our performance against the much smaller group of compensation peers described above, only some of which are included in the Russell 2000 Index.

The PSUs that were granted by the Company to our Named Executive Officers in March 2022 are eligible to vest based on the Company’s relative total shareholder return performance for the three-year period beginning March 12, 2022 and will cliff vest at the end of such three-year performance period. 100% of the target number of shares subject to the grants will vest if our total shareholder return performance equals that of the Russell 2000 Index for the performance period. If our total shareholder return exceeds that of the Russell 2000 Index for the applicable performance period, the target number of shares subject to the award that will vest is increased by 2% for each 1% of overperformance, subject to a maximum payout equal to 200% of the target number of shares. Similarly, if our total shareholder return is less than that of the Russell 2000 Index for the performance period, the target number of shares subject to the award that will vest is decreased by 2% for each 1% of underperformance, so that the award has a parallel upside leverage opportunity and downside penalty for underperformance. The payout matrix for the PSU awards can be illustrated as follows:

Payouts of April 2019 Performance Units. The performance period for the PSUs granted to each of Mr. Rittichier and Mr. Lu in April 2019 ended on April 3, 2022. We achieved a total shareholder return of (5.64)% for the

29

performance period compared to a total shareholder return of 36.27% for the Russell Microcap Index for the performance period, yielding a total shareholder return ratio relative to the Russell Microcap Index of 69.24%. As a result of underperforming the Index during the performance period, 38.48% of the target number of shares subject to Mr. Rittichier’s or Mr. Lu’s awards became vested and payable. We believe this 38.48% share payout is evidence of the performance contingent nature of our executive compensation program design at work — Mr. Rittichier and Mr. Lu each earned only a small percentage of their respective target award payout because our total shareholder return underperformed the Russell Microcap Index during the applicable performance period.

Payouts of December 2019 Performance Units. The performance period for the PSUs granted to each of Mr. Rittichier, Mr. Minichiello and Mr. Lu in December 2019 ended on December 20, 2022. We achieved a total shareholder return of (54.20)% for the performance period compared to a total shareholder return of 18.10% for the Russell Microcap Index for the performance period, yielding a total shareholder return ratio relative to the Russell Microcap Index of 38.78%. As a result of underperforming the Index during the performance period, none of the target number of shares subject to Mr. Rittichier’s or Mr. Lu’s awards became vested and payable. We believe this zero share payout is evidence of the performance contingent nature of our executive compensation program design at work — Mr. Rittichier and Mr. Lu each earned only a small percentage of their respective target award payout because our total shareholder return significantly underperformed the Russell Microcap Index during the applicable performance period.

CEO Realized Compensation

In evaluating Mr. Rittichier’s compensation, particularly his PSUs granted in March 2021 and March 2022, we believe it is important to understand not only the potential value of incentive awards at the time they are granted, but also the value actually realized by Mr. Rittichier which includes the value of the Common Stock received by Mr. Rittichier on vesting of the PSUs. The 2022 and 2021 Realized Compensation Table below supplements the Summary Compensation Table and shows the compensation actually realized in each of fiscal 2022 and fiscal 2021 by Mr. Rittichier. The primary difference between the 2022 and 2021 Realized Compensation Table below and the Summary Compensation Table is the method used to value stock awards. SEC rules require that the grant date fair value of all stock awards be reported in the Summary Compensation Table in the year in which they were awarded. As a result, a significant portion of the total compensation amounts reported in the Summary Compensation Table relate to stock awards that have not vested, a substantial portion of which are subject to performance-based vesting requirements based on performance over a three-year period ending in 2024 or 2025. Mr. Rittichier may not realize any value from these awards if his employment terminates before the awards vest or if the performance goals are not achieved. By contrast, the 2022 and 2021 Realized Compensation Table below includes only stock awards held by Mr. Rittichier that vested during fiscal 2022 or fiscal 2021, as applicable (all of which were granted at least one year prior to the applicable vesting date, and, with respect to PSUs that vested in fiscal 2022 and fiscal 2021, vested based on performance over a three year period beginning in April 2019 and ending in April 2022 and beginning in December 2017 and ending in December 2020, respectively) and shows the value of those awards as of the applicable vesting date. As shown in the table below, Mr. Rittichier’s total realized compensation calculated in this manner was $926,935 for fiscal 2022, which was $1,412,217 less than the 2022 total compensation reported in the Summary Compensation Table, and $1,286,275 for fiscal 2021, which was $1,431,643 less than the 2021 total compensation reported in the Summary Compensation Table.

Company Benefits

The Company’s benefits are an important tool in our ability to attract and retain outstanding employees throughout the Company. As a business matter, we weigh the benefits we need to offer to remain competitive and attract and retain talented employees against the cost of the benefits. Benefit levels are reviewed periodically to ensure they are cost-effective and competitive and support the overall needs of Company employees.

This section describes the benefits that the Company provides to key executives and notes those instances when benefits for the Named Executive Officers differ from the general plan. In some instances, we also describe the programs we offer across the Company as context to specific discussions about executive benefits.

Medical, Dental, and Vision Benefits

The Company offers a standard benefits package to all of its eligible employees, which includes medical, dental and vision coverage. The Named Executive Officers are also eligible to receive supplemental health benefit coverage that is not made available to non-executive employees, which provides the Named Executive Officers with additional Company-paid medical, dental and vision coverage that could be applied when their primary medical, dental or vision coverage has exceeded its coverage limit or does not provide coverage.

Company-Sponsored Retirement Plan

The EMCORE Corporation 401(k) Plan (the “401(k) Plan”) is a tax-qualified defined contribution plan that is designed to comply with the Employee Retirement Income Security Act of 1974, as well as federal and state legal requirements. The 401(k) Plan is designed to provide retirement benefits to eligible employees of the Company.

Eligible employees, including the Company’s Named Executive Officers, may elect to contribute to the 401(k) Plan through salary reduction up to the yearly maximum tax-deductible deferral allowed pursuant to IRS regulations. A participant may elect to defer between 1-90% of his or her compensation per pay period. Each participant is able to direct his or her investment into any of the available investment options. Participants’ contributions are vested at 100%.

31

The Company may provide a discretionary match of a participant’s contribution to the 401(k) Plan. During fiscal 2021 and fiscal 2022, this discretionary match was 100% of the first 3% of a participant’s contribution to the 401(k) Plan plus 50% of the next 2% of a participant’s contribution to the 401(k) Plan, subject to certain IRS limits, with such matching contributions vesting immediately.

Employee Stock Purchase Plan

Until September 9, 2021, the Company maintained a tax-qualified employee stock purchase plan (“ESPP”) that offered all eligible employees, including the Company’s Named Executive Officers, the opportunity to acquire an ownership interest in the Company by purchasing shares of Common Stock through the ESPP. On September 9, 2021, the Compensation Committee approved the termination of the ESPP, effective immediately.

Officer and Director Share Purchase Plan

In January 2011, the Compensation Committee of the Board of Directors approved an Officer and Director Share Purchase Plan (the “ODPP”), which allows executive officers and directors of the Company to purchase shares of Common Stock at fair market value in lieu of salary or, in the case of directors, director fees. Eligible individuals may voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions from director fees for the purpose of purchasing shares of Common Stock. Elections to participate in the ODPP may only be made during open trading windows under the Company’s insider trading policy and when the participant does not otherwise possess material non-public information concerning the Company.

Perquisites and Other Personal Benefits

We generally do not provide our executive officers, including Named Executive Officers, with perquisites or other personal benefits, except for supplemental health benefit coverage (as described above under “Medical, Dental, and Vision Benefits”), and, in the case of our CFO, reimbursement of certain modest commuting expenses, including airfare, ground transportation, lodging and meals, related to Mr. Minichiello’s travel to and from his home and the Company’s headquarters. These items are provided because we believe that they serve a necessary business purpose and represent an immaterial element of our executive compensation program. We do not provide tax reimbursements or any other tax payments with respect to perquisites, including excise tax “gross-ups,” to any of our executive officers.

Severance Benefits

Messrs. Rittichier and Minichiello. In an effort to further promote the retention of the Company’s Named Executive Officers, the Company previously entered into an executive employment agreement with Mr. Rittichier in connection with his appointment as our Chief Executive Officer effective January 3, 2015 and approved an executive employment agreement with Mr. Minichiello in connection with his appointment as our Chief Financial Officer effective August 26, 2019. These agreements set forth each executive’s severance benefits for a qualifying termination by us without good “cause” or by the executive for “good reason” (as those terms are defined in each executive’s employment agreement). We do not believe that the Named Executive Officers should be entitled to receive their cash severance benefits merely because a change in control transaction occurs, and a change in control does not, in and of itself, entitle any Named Executive Officer to receive cash severance benefits (i.e., these severance benefits are “double-trigger” benefits).

For more information regarding potential payments that may be made to Messrs. Rittichier and Minichiello upon a qualifying termination of employment or a change in control, see “Executive Compensation — Potential Payments upon Termination or Change-in-Control.”

Mr. Lu. Mr. Lu’s employment was terminated by the Company without cause effective November 25, 2022 (the “Lu Separation Date”). The Company and Mr. Lu entered into a separation and general release agreement,

32

effective as of January 10, 2023 (the “Lu Separation Agreement Effective Date”) (such agreement, the “Lu Separation Agreement”), pursuant to which the Company agreed to provide Mr. Lu with severance benefits that are consistent with the Compensation Committee’s guidelines for involuntary executive terminations in consideration for Mr. Lu’s execution and non-revocation of a release of claims in favor of the Company and his agreeing to comply with certain confidentiality, non-solicitation and other meaningful restrictive covenants. Under the Lu Separation Agreement, (1) all outstanding restricted stock units held by Mr. Lu as of the Lu Separation Date, which totaled of 33,646 restricted stock units, vested in full as of the Lu Separation Agreement Effective Date and (2) all outstanding performance stock units held by Mr. Lu as of the Lu Separation Date, which totaled 221,135 performance stock units at “target performance” level, vested at “target performance” level as of the Lu Separation Agreement Effective Date. Such vested restricted stock units were paid in an equivalent number of whole shares of Company common stock on January 12, 2023 and such vested performance stock units were paid in an equivalent number of whole shares of Company common stock on January 11, 2023. In entering into the Lu Separation Agreement, the Compensation Committee determined that the “value” of the accelerated restricted stock units and performance stock units, which is less than fifty percent (50%) of Mr. Lu’s total annual base compensation and target bonus, was reasonable and competitive market severance under the circumstances. The Compensation Committee made the determination to pay Mr. Lu severance in equity compensation in lieu of cash to preserve the Company’s cash resources.

Clawback Policy

We maintain a compensation recoupment policy whereby in the event of a restatement of our financial statements to correct a material error, the Compensation Committee is required to review our incentive compensation awards and may, if it determines appropriate after considering all relevant facts and circumstances, require the reimbursement of the incremental incentive compensation that an executive officer received as a result of the incorrect financial results. Annual bonus payments, long-term cash incentives, stock options, restricted stock, restricted stock units (including performance stock units) and other equity incentive awards that are granted, earned or vested based wholly or in part upon the attainment of a financial reporting measure are each subject to the terms of this clawback policy. We will revise our clawback policy to incorporate SEC clawback policy requirements once the Nasdaq listing rules are released and become effective.

Stock Ownership and Holding Requirements

We maintain a stock ownership policy. We believe that this policy aligns the interests of our executive officers with those of our shareholders by requiring executive officers to have direct ownership in shares of our Common Stock. The policy requires our Chief Executive Officer to own shares of our Common Stock having a value equal to at least three times his or her annual base salary and our other executive officers to own shares of our Common Stock having a value equal to at least one times his or her annual base salary. Shares subject to stock options and unvested stock unit awards are not considered owned by the executive for purposes of the policy. The executives covered by the policy are required to be in compliance with the ownership levels above within five years after the date such person is appointed as an executive officer, and are required to retain at least 50% of the net after-tax shares received in respect of equity awards until they are in compliance.

Anti-Hedging, Pledging and Derivatives Policy

The Company considers it improper and inappropriate for the Company’s directors, executive officers and other employees to engage in short-term or speculative transactions in the Company’s securities and other transactions in the Company’s securities that create the potential for heightened legal risk or the appearance of improper or inappropriate conduct even if they occur at a time when the individual is not aware of material nonpublic information. Accordingly, the Company prohibits these individuals from engaging in short-term trading of the Company’s securities, short sales, transactions in puts, calls, or other derivative securities related to the Company’s stock on an exchange or in any other organized market, entering into hedging or monetization transactions that are designed to hedge or offset any decrease in the market value of the Company’s securities, margining Company securities held in a margin account, or pledging Company securities as collateral for a loan.

33

Tax and Accounting Considerations

Section 162(m) of the Internal Revenue Code (“Section 162(m)”) generally disallows a tax deduction to public companies for compensation in excess of $1 million paid to a company’s chief executive officer and certain current and former executive officers. The Compensation Committee considers, among other relevant factors, the deductibility of compensation when it reviews our compensation plans and policies. However, there can be no assurance that any compensation will, in fact, be deductible, and the Compensation Committee may award non-deductible compensation when it determines it to be appropriate.

34

EXECUTIVE COMPENSATION

The table below sets forth certain information concerning the compensation paid to or earned by those persons who during fiscal 2022 served as the Company’s Chief Executive Officer, and our CFO and former SVP and GM, Aerospace and Defense, who were our two most highly compensated executive officers during fiscal 2022 other than our Chief Executive Officer. Because we qualify as a “smaller reporting company,” compensation information is provided for the fiscal years ended September 30, 2022 and 2021. Additional information regarding the compensation realized by our Chief Executive Officer in fiscal 2022 and fiscal 2021 can be found in the “CEO Realized Compensation” section of the “Compensation Discussion and Analysis” on page 25.

Summary Compensation Table

The following table sets forth as to each Named Executive Officer information about the grants of plan-based awards during fiscal 2022. Each of the equity-based awards was granted under the Company’s 2019 Equity Incentive Plan, and cash-based bonuses were awarded under the Short-Term Incentive Plan.

Options Exercised and Stock Vested in Fiscal 2022

Potential Payments upon Termination or Change-in-Control

Employment Agreements with Messrs. Rittichier and Minichiello

In an effort to further promote the retention of Messrs. Rittichier and Minichiello, the Compensation Committee previously approved an executive employment agreement with Mr. Rittichier in connection with his appointment as our Chief Executive Officer effective January 3, 2015 and approved an executive employment agreement with Mr. Minichiello in connection with his appointment as our Chief Financial Officer effective August 26, 2019. Each employment agreement provides that the respective officer’s employment is “at-will” and may be terminated by Mr. Rittichier or Mr. Minichiello, as applicable, or by the Company at any time with or without cause, subject only to the severance obligations set forth in the applicable employment agreement.

In accordance with the terms of Mr. Rittichier’s agreement, if (a) his employment is terminated without “cause” or (b) he terminates his employment for “good reason,” he will receive the following benefits: (i) continued payment of his base salary for a period of twelve months; (ii) payment of his target annual bonus for the year of termination; and (iii) payment of certain continued health coverage premiums for twelve months. Mr. Rittichier’s employment agreement also provides that he is entitled to acceleration and immediate vesting of 50% of his outstanding equity awards in the event of a “change in control” of the Company.    In addition, if Mr. Rittichier’s employment is terminated without cause or he terminates his employment for good reason within twelve months of a change in control of the Company, under the terms of his employment agreement, Mr. Rittichier is also entitled to acceleration and immediate vesting of 50% of his outstanding equity awards that remain subject to vesting (excepting those which were previously vested due to a change in control, as described above). The terms “cause,” “good reason” and “change in control” as referenced in relation to Mr. Rittichier’s employment agreement are each defined in Mr. Rittichier’s employment agreement.

In accordance with the terms of Mr. Minichiello’s agreement, if (a) his employment is terminated without “cause” or (b) he terminates his employment for “good reason,” he will receive the following benefits: (i) continued payment of his base salary for a period of twelve months; (ii) payment of his target annual bonus

38

for the year of termination; and (iii) payment of certain continued health coverage premiums for twelve months. In addition, if Mr. Minichiello’s employment is terminated without cause or he terminates his employment for good reason within twelve months of a “change in control” of the Company, under the terms of his employment agreement, Mr. Minichiello is also entitled to acceleration and immediate vesting of all of his outstanding equity awards (with any awards subject to performance-based vesting requirements vesting at a minimum of the target performance level). The terms “cause,” “good reason” and “change in control” as referenced in relation to Mr. Minichiello’s employment agreement are each defined in Mr. Minichiello’s employment agreement.

Receipt of the severance benefits described above for Messrs. Rittichier and Minichiello is subject to the executive entering into a general release agreement with the Company and compliance with certain confidentiality, nondisclosure and other restrictive covenants set forth in the applicable employment agreement.

Under the terms of each employment agreement, the initial base salary of each of Mr. Rittichier or Mr. Minichiello was established as described in more detail below. The base salary of each of Mr. Rittichier or Mr. Minichiello will continue to be determined annually by the Compensation Committee, which may, in its sole and absolute discretion, increase Mr. Rittichier’s or Mr. Minichiello’s base salary, but may not decrease it below Mr. Rittichier’s or Mr. Minichiello’s initial base salary without Mr. Rittichier’s or Mr. Minichiello’s consent, as applicable. In addition, each of Mr. Rittichier and Mr. Minichiello are entitled to participate in any of the Company’s annual bonus or pay-for-performance plans, with Mr. Rittichier entitled to a target annual cash bonus of 80% of his base salary (which was increased to 90% of his base salary in connection with the Compensation Committee’s December 2020 compensation review and increased to 100% of his base salary in connection with the Compensation Committee’s March 2022 compensation review) and Mr. Minichiello entitled to a target annual cash bonus of 50% of his base salary (which was increased to 75% of his base salary in connection with the Compensation Committee’s March 2022 compensation review). Each of Mr. Rittichier or Mr. Minichiello will be eligible for equity awards under the Company’s equity award plans covering senior executives, in each case, as may be in effect from time to time and as approved by the Compensation Committee in its sole and absolute discretion.

In the event a payment or benefit provided under the employment agreement would constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), then such payment or benefit will be limited as provided in the employment agreement. None of the employment agreements provide for any tax “gross up” or similar payment for any excise taxes that may be triggered by the payment of any parachute payments.

The following are estimated payments and benefits that would be provided to each of Mr. Rittichier and Mr. Minichiello in the event the Named Executive Officer’s employment is terminated as described above. In accordance with applicable SEC disclosure rules, the estimates assume a termination date of September 30, 2022, the last business day of fiscal 2022. The actual amounts of the payments and costs of the benefits, however, can only be determined at the time of an executive’s separation from the Company.

In addition, as of September 30, 2022, Messrs. Rittichier and Minichiello would realize the following gains from the acceleration of unvested equity awards under the circumstances described above, measured based on a stock price of $1.67, which was the per share closing price of the Common Stock on the Nasdaq Global Market on September 30, 2022, the last trading day of fiscal 2022, assumes a change of control occurred on September 30, 2022, and assumes the acceleration and payout of PSUs at target levels:

39

If Mr. Rittichier’s or Mr. Minichiello’s employment is terminated for cause or he terminates his employment without good reason, the Company will pay the Named Executive Officer’s base salary through the effective date of his termination and will not have any additional obligations to the Named Executive Officer. If the Named Executive Officer’s employment terminates as a result of his death, the Company will pay the Named Executive Officer’s base salary through the effective date of his termination and provide his spouse and children health insurance coverage as in effect on the date of termination for a period of twelve months thereafter (at a cost to the Company as of September 30, 2022 in the amount set forth in the table above under “Continued Health Coverage (Company Part Only)”).

PROPOSAL II:

AMENDMENT TO THE 2019 EQUITY INCENTIVE PLAN

General

At the Annual Meeting, shareholders will be asked to approve an amendment to the 2019 Equity Incentive Plan. The 2019 Equity Incentive Plan was amended and restated, subject to shareholder approval, by the Board of Directors on December 8, 2022.

The proposed amendment and restatement of the 2019 Equity Incentive Plan would (i) increase the number of shares available under the 2019 Equity Incentive Plan by 1,549,000 shares of Common Stock, to an aggregate of 9,262,160 shares, (ii) increase the number of shares authorized for grant as incentive stock options by the same 9,262,160 shares of Common Stock, and (iii) provide greater specificity on how awards vest in connection with a change of control (as defined in the 2019 Equity Incentive Plan).

The Company believes that incentives and stock-based awards focus employees on the objective of creating shareholder value and promoting the success of the Company, and that incentive compensation plans like the 2019 Equity Incentive Plan are an important attraction, retention and motivation tool for participants in the plan. The Board of Directors believes that the number of shares currently available under the 2019 Equity Incentive Plan does not give the Company sufficient authority and flexibility to adequately provide for future incentives. Under applicable listing rules, we may not increase the 2019 Equity Incentive Plan share limit without shareholder approval.

As of December 31, 2022, a total of 5,025,976 shares of Common Stock were subject to outstanding awards granted under the 2019 Equity Incentive Plan (assuming the achievement of maximum level of performance for performance-based awards), a total of 9,981 shares of Common Stock were then subject to outstanding awards granted under the Company’s 2012 Equity Incentive Plan, as amended and restated, and the Company’s 2010 Equity Incentive Plan, as amended (collectively, the “Prior Plans”) (which will be available for new grants under the 2019 Equity Incentive Plan if such awards are forfeited, terminated, cancelled, or expire prior to being vested or exercised, as applicable), an additional 1,097,932 shares of Common Stock were then available for new award grants under the 2019 Equity Incentive Plan (before giving effect to the increase in the aggregate share limit being requested in this Proposal II), a total of 341,000 shares of Common Stock were then subject to outstanding awards granted under the 2022 New Employee Inducement Plan and an additional 31,000 shares of Common Stock were then available for new award grants under the 2022 New Employee Inducement Plan. No new awards may be granted under the Prior Plans.

Based solely on the closing price of Common Stock, as reported on the Nasdaq Global Market on January 18, 2023, the maximum aggregate market value of the 1,549,000 new shares that could be issued under the amended 2019 Equity Incentive Plan is $1,812,330. If shareholders do not approve the amended version of the 2019 Equity Incentive Plan, the Company will continue to have the authority to grant awards under the existing terms of the 2019 Equity Incentive Plan from the shares currently available for issuance under the 2019 Equity Incentive Plan.

45

The following table shows the total number of shares of Common Stock that were subject to outstanding restricted stock and restricted stock unit awards granted under the 2019 Equity Incentive Plan, the Prior Plans and the 2022 New Employee Inducement Plan, that were subject to outstanding stock options granted under the Prior Plans, and that were then available for new award grants under the 2019 Equity Incentive Plan and the 2022 New Employee Inducement Plan, in each case as of December 31, 2021. For PSUs granted under our performance-based long-term equity award program, the number of shares presented is based on achieving the maximum level of performance, even though the actual share payout for these awards may be less than the maximum number below.

As of December 31, 2022, the Company’s 9,981 outstanding stock options granted under the Prior Plans had a weighted average exercise price of $4.52 and a weighted-average remaining life of 2.28 years, as reflected in the following table:

The following paragraphs include additional information to help shareholders assess the potential dilutive impact of the Company’s equity awards and the amended 2019 Equity Incentive Plan. The discussion that follows in this section does not include any shares that have been purchased under or that remain available for issuance or delivery under the Company’s Employee Stock Purchase Plan (“ESPP”) and the Company’s Officer and Director Share Purchase Plan (“ODPP”). The ESPP was intended as a qualified employee share purchase plan under Section 423 of the Code. The ESPP generally provided for broad-based participation by employees of the Company and certain of its subsidiaries and afforded employees who elected to participate an opportunity to purchase shares of Common Stock at a discount. The ESPP terminated on September 9, 2021. The number of approved shares to issue under the ESPP was 3,250,000, and 3,129,516 shares were issued from the ESPP through its termination on September 9, 2021 (determined using the actual number of shares issued). The ODPP solely permits officers, employees and directors to purchase fully vested shares of Common Stock at fair market value. The number of approved shares to purchase under the ODPP is 500,000, and 411,259 shares have been purchased under the plan through December 31, 2022.

“Overhang” refers to the number of shares of Common Stock that are subject to outstanding awards or remain available for new award grants. Please see the table in the “General” section above with respect to the total number of shares of Common Stock that were subject to outstanding restricted stock and restricted stock unit awards granted under the 2019 Equity Incentive Plan, the Prior Plans and the 2022 New Employee Inducement Plan, that were subject to outstanding stock options granted under the 2019 Equity Incentive Plan, the Prior Plans and the 2022 New Employee Inducement Plan and that were then available for new award grants under the 2019 Equity Incentive Plan and the 2022 New Employee Inducement Plan as of December 31, 2022.

Other than the ODPP, (i) the 2019 Equity Incentive Plan, the Prior Plans and the 2022 New Employee Inducement Plan are the Company’s only equity plans with outstanding awards, and (ii) the 2019 Equity Incentive Plan and the 2022 New Employee Inducement Plan are the Company’s only equity plans with shares that remain available for new award grants.

46

The weighted-average number of shares of Common Stock outstanding in each of the last three fiscal years was 29.1 million shares outstanding in fiscal 2020, 34.0 million shares outstanding in fiscal 2021 and 37.3 million shares outstanding in fiscal 2022. The number of shares of Common Stock outstanding as of September 30, 2022 and December 31, 2022 was approximately 37.591 million and 37.869 million shares, respectively.

“Burn rate” refers to the number of shares that are subject to awards that the Company grants over a particular period of time. The total number of shares of Common Stock subject to awards that the Company granted under the 2019 Equity Incentive Plan and its other equity compensation plans in each of the last three fiscal years, and to date (as of December 31, 2022) for fiscal year 2023, is set forth in the table below.

Through December 31, 2022, for fiscal 2023, zero stock options have been granted, 35,900 non performance-based restricted stock units have been granted and zero performance-based restricted shares or restricted stock units have been earned, for a total of 35,900 (which was 0.095% of the number of shares of Common Stock outstanding on December 31, 2022).

The total number of shares of Common Stock that were subject to awards granted under the 2019 Equity Incentive Plan, the Prior Plans or the 2022 New Employee Inducement Plan that terminated or expired, and thus became available for new award grants under the 2019 Equity Incentive Plan, the Prior Plans or the 2022 New Employee Inducement Plan, in each of the last three fiscal years (2020, 2021 and 2022), and to date (as of December 31, 2022) in fiscal 2023, are as follows: 339,767 in fiscal 2020, 316,292 in fiscal 2021, 406,231 in fiscal 2022 and 509,068 to date in fiscal 2023. Shares subject to the 2019 Equity Incentive Plan, the Prior Plans or the 2022 New Employee Inducement Plan awards that terminated or expired and became available for new award grants under the 2019 Equity Incentive Plan, the Prior Plans or the 2022 New Employee Inducement Plan have been included when information is presented in this amended 2019 Equity Incentive Plan proposal on the number of shares available for new award grants under the 2019 Equity Incentive Plan.

When considering the number of shares to add to the 2019 Equity Incentive Plan, the Compensation Committee reviewed, among other things, the potential dilution to the Company’s current shareholders as measured by burn rate and overhang, projected future share usage, and projected future forfeitures. The Compensation Committee anticipates that the 1,549,000 additional shares requested for the 2019 Equity Incentive Plan (together with the shares available for new award grants under the 2019 Equity Incentive Plan as of December 31, 2022, and assuming usual levels of shares becoming available for new awards as a result of forfeitures of outstanding awards) will provide the Company with flexibility to continue to grant equity awards under the 2019 Equity Incentive Plan through approximately March 2024. However, this is only an estimate, in the Company’s judgment, based on current circumstances. The total number of shares that are subject to the Company’s award grants in any one year or from year-to-year may change based on a number of variables, including, without limitation, the value of the Common Stock (since higher stock prices generally require that fewer shares be issued to produce awards of the same grant date fair value), changes in competitors’ compensation practices or changes in compensation practices in the market generally, changes in the number of employees, changes in the number of directors and officers, whether and the extent to which vesting conditions applicable to equity-based awards are satisfied, acquisition activity and the need to grant awards to new employees in connection with

47

acquisitions, the need to attract, retain and incentivize key talent, the type of awards the Company grants, and how the Company chooses to balance total compensation between cash and equity-based awards. The Compensation Committee is committed to effectively managing the number of shares reserved for issuance under the 2019 Equity Incentive Plan while minimizing shareholder dilution.

The closing market price for a share of the Common Stock as of December 31, 2022 was $0.96 per share.

Summary Description of the 2019 Equity Incentive Plan (as Proposed to be Amended)

The principal terms of the 2019 Equity Incentive Plan (as proposed to be amended) are summarized below. The following summary is qualified in its entirety by the full text of the 2019 Equity Incentive Plan (as proposed to be amended), which appears as Appendix A to this Proxy Statement.

Purpose. The purpose of the 2019 Equity Incentive Plan is to promote the success of the Company by providing an additional means for us to attract, motivate, retain and reward selected employees and other eligible persons through the grant of awards. Equity-based awards are also intended to further align the interests of award recipients and our shareholders.

Administration. Our Board of Directors or one or more committees appointed by our Board of Directors administers the 2019 Equity Incentive Plan. Currently, our Board of Directors has delegated general administrative authority for the 2019 Equity Incentive Plan to the Compensation Committee. The Board of Directors or a committee thereof (within its delegated authority) may delegate different levels of authority to different committees or persons with administrative and grant authority under the 2019 Equity Incentive Plan. (The appropriate acting body, be it the Board of Directors or a committee or other person within its delegated authority is referred to in this proposal as the “Administrator”).

The Administrator has broad authority under the 2019 Equity Incentive Plan, including, without limitation, the authority:

48

Minimum Vesting Requirement. All awards granted under the 2019 Equity Incentive Plan are subject to a minimum vesting requirement of one year, and no portion of any such award may vest earlier than the first anniversary of the grant date of the award. This minimum vesting requirement does not apply to 5% of the total number of shares available under the 2019 Equity Incentive Plan.

No Repricing. In no case (except due to an adjustment to reflect a stock split or other event referred to under “Adjustments” below, or any repricing that may be approved by shareholders) will the Administrator (1) amend an outstanding stock option or stock appreciation right to reduce the exercise price or base price of the award, (2) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for cash or other awards for the purpose of repricing the award, or (3) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for an option or stock appreciation right with an exercise or base price that is less than the exercise or base price of the original award.

Eligibility. Persons eligible to receive awards under the 2019 Equity Incentive Plan include officers or employees of the Company or any of its subsidiaries, directors of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. Currently, approximately 440 officers and employees of the Company and its subsidiaries (including all of the Company’s named executive officers), and each of the four members of the Board of Directors who are not employed by the Company or any of its subsidiaries (“Non-Employee Directors”), are considered eligible under the 2019 Equity Incentive Plan.

Aggregate Share Limit. The maximum number of shares of Common Stock that may be issued or transferred pursuant to awards under the 2019 Equity Incentive Plan equals the sum of the following (such total number of shares, the “Share Limit”):

Additional Share Limits. The following other limits are also contained in the 2019 Equity Incentive Plan. These limits are in addition to, and not in lieu of, the Share Limit for the plan described above.

49

Share-Limit Counting Rules. The Share Limit of the 2019 Equity Incentive Plan is subject to the following rules:

50

In addition, the 2019 Equity Incentive Plan generally provides that shares issued in connection with awards that are granted by or become obligations of the Company through the assumption of awards (or in substitution for awards) in connection with an acquisition of another company will not count against the shares available for issuance under the 2019 Equity Incentive Plan. The Company may not increase the applicable share limits of the 2019 Equity Incentive Plan by repurchasing shares of common stock on the market (by using cash received through the exercise of stock options or otherwise).

Types of Awards. The 2019 Equity Incentive Plan authorizes stock options, stock appreciation rights, and other forms of awards granted or denominated in Common Stock or units of Common Stock, as well as cash bonus awards. The 2019 Equity Incentive Plan retains flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. Any award may be structured to be paid or settled in cash.

A stock option is the right to purchase shares of Common Stock at a future date at a specified price per share (the “exercise price”). The per share exercise price of an option may not be less than the fair market value of a share of Common Stock on the date of grant. The maximum term of an option is ten years from the date of grant. An option may either be an incentive stock option or a nonqualified stock option. Incentive stock option benefits are taxed differently from nonqualified stock options, as described under “U.S. Federal Income Tax Consequences of Awards Under the Amended 2019 Equity Incentive Plan” below. Incentive stock options are also subject to more restrictive terms and are limited in amount by the U.S. Internal Revenue Code and the 2019 Equity Incentive Plan. Incentive stock options may only be granted to employees of the Company or a subsidiary.

A stock appreciation right is the right to receive payment of an amount equal to the excess of the fair market value of share of Common Stock on the date of exercise of the stock appreciation right over the base price of the stock appreciation right. The base price will be established by the Administrator at the time of grant of the stock appreciation right and may not be less than the fair market value of a share of Common Stock on the date of grant. Stock appreciation rights may be granted in connection with other awards or independently. The maximum term of a stock appreciation right is ten years from the date of grant.

The other types of awards that may be granted under the 2019 Equity Incentive Plan include, without limitation, stock bonuses, restricted stock, performance stock, stock units or phantom stock (which are contractual rights to receive shares of stock, or cash based on the fair market value of a share of stock), dividend equivalents which represent the right to receive a payment based on the dividends paid on a share of stock over a stated period of time, or similar rights to purchase or acquire shares, and cash awards.

Subject to the minimum vesting requirement described above, any awards under the 2019 Equity Incentive Plan (including awards of stock options and stock appreciation rights) may be fully-vested at grant or may be subject to time- and/or performance-based vesting requirements.

Dividend Equivalents; Deferrals. The Administrator may provide for the deferred payment of awards and may determine the other terms applicable to deferrals. The Administrator may provide that awards under the 2019 Equity Incentive Plan (other than options or stock appreciation rights), and/or deferrals, earn dividends or dividend equivalents based on the amount of dividends paid on outstanding shares of Common Stock, provided that any dividends and/or dividend equivalents as to the portion of an award that is subject to unsatisfied vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied (or, in the case of a restricted stock or similar award where the dividend must be paid as a matter of law, the dividend payment will be subject to forfeiture or repayment, as the case may be, if the related vesting conditions are not satisfied).

51

Assumption and Termination of Awards. Upon the consummation of a change in control (as defined under the 2019 Equity Incentive Plan), the Administrator may make provision for a cash payment in settlement of, or for the termination, assumption, substitution or exchange of any or all outstanding awards or the cash, securities or property deliverable to the holder of any or all outstanding awards, based upon, to the extent relevant under the circumstances, the distribution or consideration payable to holders of the Common Stock upon or in respect of such event. However, if awards then-outstanding under the 2019 Equity Incentive Plan are to be terminated in such circumstances (without being assumed or substituted for), such awards would generally become fully vested (with any performance goals applicable to the award being deemed met at the “target” performance level), subject to any exceptions that the Administrator may provide for in an applicable award agreement, or any applicable change of control, employment or severance agreement. For the treatment of outstanding equity awards held by the Named Executive Officers in connection with a termination of employment and/or a change in control of the Company, please see the “Potential Payments Upon Change in Control and Termination” above in this Proxy Statement.

Transfer Restrictions. Subject to certain exceptions contained in Section 5.6 of the 2019 Equity Incentive Plan, awards under the 2019 Equity Incentive Plan generally are not transferable by the recipient other than by will or the laws of descent and distribution and are generally exercisable, during the recipient’s lifetime, only by the recipient. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient’s beneficiary or representative. The Administrator has discretion, however, to establish written conditions and procedures for the transfer of awards to other persons or entities, provided that such transfers comply with applicable federal and state securities laws and are not made for value (other than nominal consideration, settlement of marital property rights, or for interests in an entity in which more than 50% of the voting securities are held by the award recipient or by the recipient’s family members).

Adjustments. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2019 Equity Incentive Plan and any outstanding awards, as well as the exercise or purchase prices of awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the shareholders.

No Limit on Other Authority. The 2019 Equity Incentive Plan does not limit the authority of the Board of Directors or any committee to grant awards or authorize any other compensation, with or without reference to Common Stock, under any other plan or authority.

Administrative Discretion. The minimum vesting requirement described above shall not limit or restrict the Administrator’s discretion to accelerate the vesting of any awards granted under the amended 2019 Equity Incentive Plan in circumstances it determines to be appropriate (whether in connection with a transaction, termination of employment or for any other reason).

Termination of or Changes to the 2019 Equity Incentive Plan. The Board of Directors may amend or terminate the 2019 Equity Incentive Plan at any time and in any manner. Shareholder approval for an amendment will be required only to the extent then required by applicable law or deemed necessary or advisable by the Board of Directors. Unless terminated earlier by the Board of Directors and subject to any extension that may be approved by shareholders, the authority to grant new awards under the 2019 Equity Incentive Plan will terminate on December 9, 2028. Outstanding awards, as well as the Administrator’s authority with respect thereto, generally will continue following the expiration or termination of the plan. Generally speaking, outstanding awards may be amended by the Administrator (except for a repricing), but the consent of the award holder is required if the amendment (or any plan amendment) materially and adversely affects the holder.

U.S. Federal Income Tax Consequences of Awards under the Amended 2019 Equity Incentive Plan

The U.S. federal income tax consequences of the amended 2019 Equity Incentive Plan under current federal law, which is subject to change, are summarized in the following discussion of the general tax principles applicable to

52

the 2019 Equity Incentive Plan. This summary is not intended to be exhaustive and, among other considerations, does not describe the deferred compensation provisions of Section 409A of the U.S. Internal Revenue Code to the extent an award is subject to and does not satisfy those rules, nor does it describe state, local, or international tax consequences.

With respect to nonqualified stock options, the company is generally entitled to deduct and the participant recognizes taxable income in an amount equal to the difference between the option exercise price and the fair market value of the shares at the time of exercise. With respect to incentive stock options, the company is generally not entitled to a deduction nor does the participant recognize income at the time of exercise, although the participant may be subject to the U.S. federal alternative minimum tax.

The current federal income tax consequences of other awards authorized under the 2019 Equity Incentive Plan generally follow certain basic patterns: nontransferable restricted stock subject to a substantial risk of forfeiture results in income recognition equal to the excess of the fair market value over the price paid (if any) only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant); bonuses, stock appreciation rights, cash and stock-based performance awards, dividend equivalents, stock units, and other types of awards are generally subject to tax at the time of payment; and compensation otherwise effectively deferred is taxed when paid. In each of the foregoing cases, the company will generally have a corresponding deduction at the time the participant recognizes income.

If an award is accelerated under the 2019 Equity Incentive Plan in connection with a “change in control” (as this term is used under the U.S. Internal Revenue Code), the Company may not be permitted to deduct the portion of the compensation attributable to the acceleration (“parachute payments”) if it exceeds certain threshold limits under the U.S. Internal Revenue Code (and certain related excise taxes may be triggered). Furthermore, under Section 162(m) of the Code, the aggregate compensation in excess of $1,000,000 attributable to awards held by current or former Named Executive Officers may not be deductible by the Company.

Specific Benefits under the Amended 2019 Equity Incentive Plan

The Company has not approved any awards that are conditioned upon shareholder approval of the amended 2019 Equity Incentive Plan. Except as described below, the Company is not currently considering any other specific award grants under the amended 2019 Equity Incentive Plan.

As described under “Director Compensation Policy” above, under our current Director Compensation Policy, each Non-Employee Director receives, once every three years, an award of restricted stock units on the date of the Company’s annual meeting of shareholders, with the number of shares subject to each award to be determined by dividing $225,000 (or in the case of our Chairperson, $352,500) by the closing price of our common stock on the grant date. The restricted stock units vest as to one-third of the award on each of the first three anniversaries of the grant date (or, if the Company’s annual meeting of shareholders for the applicable year occurs prior to such vesting date, on the day prior to that annual meeting), subject to the Non-Employee Director’s continued service on the Board of Directors through such vesting date. Unvested restricted stock units will also vest upon a director’s earlier termination of service due to death or disability. Equity grants for the Non-Employee Directors will be awarded under the 2019 Equity Incentive Plan regardless of whether shareholders approve the amended 2019 Equity Incentive Plan.

The Company cannot project the grants that may be made to the Company’s officers and employees because such grants are made at the discretion of the Compensation Committee. If the amended 2019 Equity Incentive Plan had been in effect in fiscal year 2022, we expect that our award grants for fiscal year 2022 would not have been substantially different from those actually made in that year under the current version of the 2019 Equity Incentive Plan. For information regarding stock-based awards granted to the Named Executive Officers during fiscal year 2022, please see the “Executive Compensation” section of this Proxy Statement.

Equity Compensation Plan Information

The table on page 36 of this Proxy Statement under the heading “Equity Compensation Plan Information” sets forth, as of September 30, 2022, the number of securities outstanding under each of the Company’s compensation plans under which equity securities are authorized for issuance, the weighted average exercise price of outstanding options, and the number of securities available for grant under such plans.

Aggregate Past Grants under the 2019 Equity Incentive Plan

As of December 31, 2022, awards covering 6,769,959 shares of our common stock had been granted under the 2019 Equity Incentive Plan. This number of shares includes shares subject to awards under the 2019 Equity Incentive Plan that expired, were cancelled or terminated without having been exercised and paid and became available for new award grants under the 2019 Equity Incentive Plan. No stock options have been granted under the 2019 Equity Incentive Plan since inception of the 2019 Equity Incentive Plan.

Vote Required for Approval of Amendment to the 2019 Equity Incentive Plan

The Board of Directors believes that the adoption of the amended 2019 Equity Incentive Plan will promote the interests of the Company and its shareholders and will help the Company and its subsidiaries continue to be able to attract, retain and reward persons important to our success.

All members of the Board of Directors and all of the Company’s executive officers are eligible for awards under the amended 2019 Equity Incentive Plan and thus have a personal interest in the approval of the amended 2019 Equity Incentive Plan.

Approval of the amended 2019 Equity Incentive Plan requires the affirmative vote of a majority of the votes cast and entitled to vote on the proposal at the Annual Meeting.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE “FOR” APPROVAL OF AMENDMENT TO THE 2019 EQUITY INCENTIVE PLAN AS DESCRIBED ABOVE UNDER PROPOSAL II AND SET FORTH IN APPENDIX A HERETO. Unless otherwise instructed, the proxyholders will vote all properly submitted proxies “FOR” approval of amendment to the 2019 Equity Incentive Plan.

54

PROPOSAL III:

ADVISORY VOTE ON EXECUTIVE COMPENSATION

In accordance with the requirements of Section 14A of the Exchange Act (which was added by the Dodd-Frank Wall Street Reform and Consumer Protection Act) and the related compensation disclosure rules of the SEC, and consistent with our shareholders’ preference to provide annual advisory votes on the compensation of our Named Executive Officers, we are asking our shareholders to vote to approve, on a non-binding, advisory basis, the compensation of our Named Executive Officers as disclosed in this Proxy Statement.

As described in detail under the heading “Compensation Discussion and Analysis,” we seek to closely align the interests of our Named Executive Officers with the interests of our shareholders. Our compensation programs are designed to reward our Named Executive Officers for the achievement of short-term and long-term strategic and operational goals, while at the same time avoiding the encouragement of unnecessary or excessive risk-taking.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the overall compensation of our Named Executive Officers, as described in this Proxy Statement. The vote is advisory, which means that the vote is not binding on the Company, our Board of Directors or the Compensation Committee of the Board of Directors. Although the vote is non-binding, the Compensation Committee will consider the voting results when it evaluates whether any changes should be made to the Company’s compensation program.

Accordingly, we ask our shareholders to approve the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s shareholders approve, on an advisory basis, the compensation paid to the Company’s Named Executive Officers as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables, and the related narrative disclosure in this Proxy Statement.”

Our current policy is to provide our shareholders with an opportunity to approve the compensation of the Company’s Named Executive Officers each year at the annual meeting of shareholders. We expect that the next advisory vote on the compensation of our Named Executive Officers will occur at our 2024 Annual Meeting of Shareholders.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS UNDER PROPOSAL III, AS DISCLOSED IN THIS PROXY STATEMENT. Unless otherwise instructed, the proxyholders will vote all properly submitted proxies “FOR” approval of the compensation of the Company’s Named Executive Officers.

55

PROPOSAL IV:

ADVISORY VOTE ON FREQUENCY OF VOTES ON EXECUTIVE COMPENSATION

Section 14A of the Exchange Act (which was added by the Dodd-Frank Wall Street Reform and Consumer Protection Act) enables our shareholders to indicate their preference, at least once every six years, regarding how frequently we should solicit a non-binding advisory vote on the compensation of our Named Executive Officers. Accordingly, we are asking our shareholders to vote, on a non-binding advisory basis, to indicate how frequently we should seek future advisory votes on the compensation of our Named Executive Officers. By voting with respect to this Proposal IV, shareholders may indicate whether they would prefer that we conduct future advisory votes on executive compensation once every one, two, or three years. Shareholders also may, if they wish, abstain from casting a vote on this proposal.

Shareholders previously voted to conduct advisory votes on executive compensation annually. Accordingly, our Board of Directors has determined that continuing to provide for an annual advisory vote on executive compensation is advisable because it would allow our shareholders to provide timely, direct input on the Company’s executive compensation philosophy, policies and practices as disclosed in the proxy statement each year. The Board believes that an annual vote is therefore consistent with the Company’s efforts to engage in an ongoing dialogue with our shareholders on executive compensation and corporate governance matters.

The Company recognizes that shareholders may have different views as to the best approach for the Company, and therefore we look forward to hearing from our shareholders as to their preferences on the frequency of future advisory votes on executive compensation.

This vote is advisory and not binding on the Company or our Board of Directors. However, the Board of Directors and the Compensation Committee will take into account the outcome of the vote when considering the frequency of future advisory votes on executive compensation. The Board may decide that it is in the best interests of our shareholders and the Company to hold an advisory vote on executive compensation more or less frequently than the frequency receiving the most votes cast by our shareholders.

The proxy card provides shareholders with the opportunity to choose among four options (holding the vote every one, two or three years, or abstaining) and, therefore, shareholders will not be voting to approve or disapprove the recommendation of the Board of Directors.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE TO HOLD SHAREHOLDER ADVISORY VOTES ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS EVERY “1 YEAR” UNDER PROPOSAL IV, AS DISCLOSED IN THIS SUPPLEMENT. Unless otherwise instructed, the proxyholders will vote all properly submitted proxies to approve a frequency of “1 YEAR” for shareholder advisory votes to approve compensation of the Company’s Named Executive Officers.

56

PROPOSAL V:

RATIFICATION OF THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

For fiscal 2022, KPMG LLP (“KPMG”) served as the Company’s independent registered public accounting firm and provided audit services that included examination of the Company’s annual consolidated financial statements. A summary of the fees for services provided by KPMG for fiscal 2022 is set forth below. The Audit Committee of the Board of Directors has appointed KPMG to serve as the Company’s independent registered public accounting firm for fiscal 2023 and the Board of Directors recommends that shareholders ratify such appointment at the Annual Meeting.

Action by the shareholders is not required by law to appoint or ratify the appointment of an independent registered public accounting firm, but ratification of KPMG’s appointment is being submitted by the Audit Committee of the Board of Directors in order to give the shareholders a voice in the designation of auditors. If the resolution ratifying the appointment of KPMG as the Company’s independent registered public accounting firm for fiscal 2023 is rejected by the shareholders, then the Audit Committee may reconsider its choice of independent registered public accounting firm. Even if the resolution is approved, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders. Proxies in the form solicited hereby that are properly submitted will be voted FOR the resolution unless otherwise instructed by the shareholder.

Representatives of KPMG are expected to attend the Annual Meeting. They will have an opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

FISCAL 2022 & 2021 AUDITOR FEES AND SERVICES

The following table presents fees for professional services provided to the Company by KPMG in fiscal 2022 and fiscal 2021:

Audit Committee Pre-Approval Policies and Procedures

The Audit Committee pre-approves all audit and permissible non-audit services provided by the independent auditors. These services may include audit services, audit-related services, tax services and other services. The Audit Committee has adopted a policy for the pre-approval of services provided by the independent auditors. Under the policy, pre-approval is generally provided for up to one year and any pre-approval is detailed as to the particular service or category of services and is subject to a specific budget. In addition, the Audit Committee may also pre-approve particular services on a case-by-case basis. For each proposed service, the independent auditors are required to provide detailed back-up documentation at the time of approval. All of the fees and services provided as noted in the table above were authorized and approved by the Audit Committee in compliance with the pre-approval policies and procedures described herein.

57

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF KPMG LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING SEPTEMBER 30, 2023 UNDER PROPOSAL V. Unless otherwise instructed, the proxyholders will vote all properly submitted proxies “FOR” ratification of the appointment of KPMG LLP as the Company’s independent registered public accounting firm for the fiscal year ending September 30, 2023.

REPORT OF THE AUDIT COMMITTEE

The following Report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act or the Exchange Act, except to the extent the Company specifically incorporates this Report of the Audit Committee by reference therein.

Management has primary responsibility for the accuracy and fairness of the Company’s consolidated financial statements as well as the processes employed to prepare the financial statements, and the system of internal control over financial reporting. KPMG LLP (“KPMG”), the Company’s independent registered public accounting firm for fiscal 2022, was responsible for performing an independent audit of the Company’s consolidated financial statements and internal control over financial reporting in accordance with the auditing standards of the Public Company Accounting Oversight Board (United States) and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The specific responsibilities of the Audit Committee are set forth in the EMCORE Corporation Audit Committee Charter, which has been adopted by the Board of Directors. The Audit Committee Charter is available in the Corporate Governance section on the Investors tab of the Company’s website (www.emcore.com).

During fiscal 2022, the Audit Committee consisted of Mr. Jackson (chairman), Mr. Domenik and Ms. Heiks. Each member of the Audit Committee is currently, and was during his or her tenure, an independent director within the meaning of applicable Nasdaq and SEC rules. The Board of Directors has determined that Mr. Jackson is an audit committee financial expert within the meaning of SEC rules. The Audit Committee met eight (8) times during fiscal 2022.

As part of its oversight role, the Audit Committee has reviewed and discussed the Company’s audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for fiscal 2022 with management of the Company and KPMG. The Audit Committee has also discussed with KPMG the matters required to be discussed by Auditing Standard 1301, Communications with Audit Committees, issued by the Public Company Accounting Oversight Board and the SEC. Furthermore, the Audit Committee has reviewed management’s assessment of the effectiveness of the Company’s internal control over financial reporting, and has reviewed the opinions of KPMG regarding the conformity of the Company’s audited financial statements with GAAP and the Company’s internal control over financial reporting.

The Audit Committee has received the written disclosures and the letter from KPMG required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with KPMG matters relating to its independence. The Audit Committee concluded that KPMG’s provision of non-audit services to the Company, as detailed above, is compatible with the accounting firm’s independence.

Based on the foregoing review and discussions, the Audit Committee recommended to the Board of Directors that the Company’s audited financial statements be included in the Company’s Annual Report on Form 10-K for fiscal 2022, which was filed with the SEC on December 28, 2022.

This report is submitted by the Audit Committee.

Appendix A

EMCORE CORPORATION

AMENDED AND RESTATED 2019 EQUITY INCENTIVE PLAN

The purpose of this EMCORE Corporation Amended and Restated 2019 Equity Incentive Plan (this “Plan”) of EMCORE Corporation, a New Jersey corporation (the “Corporation”), is to promote the success of the Corporation by providing an additional means through the grant of awards to attract, motivate, retain and reward selected employees and other eligible persons and to enhance the alignment of the interests of the selected participants with the interests of the Corporation’s stockholders.

The Administrator (as such term is defined in Section 3.1) may grant awards under this Plan only to those persons that the Administrator determines to be Eligible Persons. An “Eligible Person” is any person who is either: (a) an officer (whether or not a director) or employee of the Corporation or one of its Subsidiaries; (b) a director of the Corporation or one of its Subsidiaries; or (c) an individual consultant or advisor who renders or has rendered bona fide services (other than services in connection with the offering or sale of securities of the Corporation or one of its Subsidiaries in a capital-raising transaction or as a market maker or promoter of securities of the Corporation or one of its Subsidiaries) to the Corporation or one of its Subsidiaries and who is selected to participate in this Plan by the Administrator; provided, however, that a person who is otherwise an Eligible Person under clause (c) above may participate in this Plan only if such participation would not adversely affect either the Corporation’s eligibility to use Form S-8 to register under the Securities Act of 1933, as amended (the “Securities Act”), the offering and sale of shares issuable under this Plan by the Corporation or the Corporation’s compliance with any other applicable laws. An Eligible Person who has been granted an award (a “participant”) may, if otherwise eligible, be granted additional awards if the Administrator shall so determine. As used herein, “Subsidiary” means any corporation or other entity a majority of whose outstanding voting stock or voting power is beneficially owned directly or indirectly by the Corporation; and “Board” means the Board of Directors of the Corporation.

A-1

A-2

A-3

provided that in no event shall the Share Limit exceed 10,555,420 shares (which is the sum of the 9,262,160 shares set forth above, plus the aggregate number of shares subject to awards previously granted and outstanding under the Prior Plans as of the Stockholder Approval Date).

A-4

Refer to Section 8.10 for application of the share limits of this Plan, including the limits in Sections 4.2 and 4.3, with respect to assumed awards. Each of the numerical limits and references in Sections 4.2 and 4.3, and in this Section 4.4, is subject to adjustment as contemplated by Section 4.3, Section 7 and Section 8.10.

A-5

5.1.1    Stock Options. A stock option is the grant of a right to purchase a specified number of shares of Common Stock during a specified period as determined by the Administrator. An option may be intended as an incentive stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified stock option (an option not intended to be an ISO). The agreement evidencing the grant of an option will indicate if the option is intended as an ISO; otherwise it will be deemed to be a nonqualified stock option. The maximum term of each option (ISO or nonqualified) shall be ten (10) years. The per share exercise price for each option shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the option. When an option is exercised, the exercise price for the shares to be purchased shall be paid in full in cash or such other method permitted by the Administrator consistent with Section 5.4.

5.1.2    Additional Rules Applicable to ISOs. To the extent that the aggregate fair market value (determined at the time of grant of the applicable option) of stock with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account both Common Stock subject to ISOs under this Plan and stock subject to ISOs under all other plans of the Corporation or one of its Subsidiaries (or any parent or predecessor corporation to the extent required by and within the meaning of Section 422 of the Code and the regulations promulgated thereunder), such options shall be treated as nonqualified stock options. In reducing the number of options treated as ISOs to meet the $100,000 limit, the most recently granted options shall be reduced first. To the extent a reduction of simultaneously granted options is necessary to meet the $100,000 limit, the Administrator may, in the manner and to the extent permitted by law, designate which shares of Common Stock are to be treated as shares acquired pursuant to the exercise of an ISO. ISOs may only be granted to employees of the Corporation or one of its subsidiaries (for this purpose, the term “subsidiary” is used as defined in Section 424(f) of the Code, which generally requires an unbroken chain of ownership of at least 50% of the total combined voting power of all classes of stock of each subsidiary in the chain beginning with the Corporation and ending with the subsidiary in question). No ISO may be granted to any person who, at the time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined voting power of all classes of stock of the Corporation, unless the exercise price of such option is at least 110% of the fair market value of the stock subject to the option and such option by its terms is not exercisable after the expiration of five years from the date such option is granted. If an otherwise-intended ISO fails to meet the applicable requirements of Section 422 of the Code, the option shall be a nonqualified stock option.

5.1.3    Stock Appreciation Rights. A stock appreciation right or “SAR” is a right to receive a payment, in cash and/or Common Stock, equal to the excess of the fair market value of a specified number of shares of Common Stock on the date the SAR is exercised over the “base price” of the award, which base price shall be set forth in the applicable award agreement and shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the SAR. The maximum term of a SAR shall be ten (10) years.

5.1.4    Other Awards; Dividend Equivalent Rights. The other types of awards that may be granted under this Plan include: (a) stock bonuses, restricted stock, performance stock, stock units, restricted stock units, deferred shares, phantom stock or similar rights to purchase or acquire shares, whether at a fixed or variable price (or no price) or fixed or variable ratio related to the Common Stock, and, subject to the Minimum Vesting Requirement, any of which may (but need not) be fully vested at grant or vest upon the passage of time, the occurrence of one or more events, the satisfaction of performance criteria

A-6

or other conditions, or any combination thereof; or (b) cash awards. The types of cash awards that may be granted under this Plan include the opportunity to receive a payment for the achievement of one or more goals established by the Administrator, on such terms as the Administrator may provide, as well as discretionary cash awards. Dividend equivalent rights may be granted as a separate award or in connection with another award under this Plan; provided, however, that dividend equivalent rights may not be granted as to a stock option or SAR granted under this Plan. In addition, any dividends and/or dividend equivalents as to the portion of an award that is subject to unsatisfied vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied.

5.1.5    Performance Goals. The grant, vesting, exercisability or payment of an award may (but need not) depend on the degree of achievement of one or more performance goals relative to a pre-established targeted level or levels using business criteria as selected by the Administrator in its sole discretion.

In no event shall any shares newly-issued by the Corporation be issued for less than the minimum lawful consideration for such shares or for consideration other than consideration permitted by applicable state law. Shares of Common Stock used to satisfy the exercise price of an option shall be valued at their fair market value. The Corporation will not be obligated to deliver any shares unless and until it receives full payment of the exercise or purchase price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any time eliminate or limit a participant’s ability to pay any purchase or exercise price of any award or shares by any method other than cash payment to the Corporation.

A-7

5.6.1    Limitations on Exercise and Transfer. Unless otherwise expressly provided in (or pursuant to) this Section 5.6 or required by applicable law: (a) all awards are non-transferable and shall not be subject in any manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or charge; (b) awards shall be exercised only by the participant; and (c) amounts payable or shares issuable pursuant to any award shall be delivered only to (or for the account of) the participant.

5.6.2    Exceptions. The Administrator may permit awards to be exercised by and paid to, or otherwise transferred to, other persons or entities pursuant to such conditions and procedures, including limitations on subsequent transfers, as the Administrator may, in its sole discretion, establish in writing. Any permitted transfer shall be subject to compliance with applicable federal and state securities laws and shall not be for value (other than nominal consideration, settlement of marital property rights, or for interests in an entity in which more than 50% of the voting interests are held by the Eligible Person or by the Eligible Person’s family members).

5.6.3    Further Exceptions to Limits on Transfer. The exercise and transfer restrictions in Section 5.6.1 shall not apply to:

A-9

A-10

A-11

Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because any Person (the “Subject Person”) acquired Beneficial Ownership of fifty percent (50%) or more of the combined voting power of the then outstanding Voting Securities as a result of the acquisition of Voting Securities by the Corporation which, by reducing the number of Voting Securities then outstanding, increases the proportional number of shares Beneficially Owned by the Subject Persons, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Corporation, and (1) before such share acquisition by the Corporation the Subject Person becomes the Beneficial Owner of any new or additional Voting Securities in a related transaction or (2) after such share acquisition by the Corporation the Subject Person becomes the Beneficial Owner of any new or additional Voting Securities which in either case increases the percentage of the then outstanding Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall be deemed to occur. Solely for purposes of this Change in Control definition, (x) “Affiliate” shall mean, with respect to any Person, any other Person that, directly or indirectly, controls, is controlled by, or is under common control with, such Person; (y) any “Relative” (for this purpose, “Relative” means a spouse, child, parent, parent of spouse, sibling or grandchild) of an individual shall be deemed to be an Affiliate of such individual for this purpose; and (z) neither the Corporation nor any Person controlled by the Corporation shall be deemed to be an Affiliate of any holder of Common Stock.

A-12

8.5.1    (a) The Corporation or one of its Subsidiaries shall have the right to require the participant (or the participant’s personal representative or beneficiary, as the case may be) to pay or provide for payment of the amount of any taxes which the Corporation or one of its Subsidiaries may be required or permitted to withhold with respect to such award event or payment.

8.5.2    (b) The Corporation or one of its Subsidiaries shall have the right to deduct from any amount otherwise payable in cash (whether related to the award or otherwise) to the participant (or the participant’s personal representative or beneficiary, as the case may be) the amount of any taxes which

A-13

the Corporation or one of its Subsidiaries may be required or permitted to withhold with respect to such award event or payment.

8.5.3    (c) In any case where a tax is required to be withheld in connection with the delivery of shares of Common Stock under this Plan, the Administrator may in its sole discretion (subject to Section 8.1) require or grant (either at the time of the award or thereafter) to the participant the right to elect, pursuant to such rules and subject to such conditions as the Administrator may establish, that the Corporation reduce the number of shares to be delivered by (or otherwise reacquire) the appropriate number of shares, valued in a consistent manner at their fair market value or at the sales price in accordance with authorized procedures for cashless exercises, necessary to satisfy any applicable withholding obligation on exercise, vesting or payment.

8.6.1    Effective Date. This Plan was originally effective as of December 14, 2018, the date of its original approval by the Board (the “Effective Date”). This amended version of this Plan is effective as of December 8, 2022, the date this amended version of this Plan was approved by the Board (the “Amendment Date”).
