PROXY STATEMENT

For Annual Meeting of Shareholders

to be held on March 13, 2025

This proxy statement and the accompanying form of proxy are being furnished to you as a shareholder of DLH Holdings Corp., a New Jersey corporation (“DLH” or the “Company”), in connection with the Annual Meeting of Shareholders to be held on March 13, 2025 at 10:00 a.m. (Eastern time) and at any adjournment or postponement of the meeting. The Company has determined that the 2025 Annual Meeting will be a “hybrid meeting” so that shareholders can either attend physically or remotely via the Internet. We believe that this will facilitate shareholder attendance and participation while safeguarding the health and safety of our shareholders, directors and management team. Accordingly, we will be hosting the meeting in-person at the offices of Becker & Poliakoff, 45 Broadway, 17th Floor, New York, NY 10006 and via the Internet at https://www.cstproxy.com/dlhcorp/2025.

Shareholders will be able to vote and pose questions regardless of how they may choose to attend the meeting. Shareholders choosing to attend virtually via the Internet will be able to access the Annual Meeting and vote and submit questions by visiting https://www.cstproxy.com/dlhcorp/2025 and entering the control number assigned by Continental Stock Transfer & Trust Company. This proxy statement and the accompanying form of proxy is being made available on or about January 28, 2025 to shareholders entitled to vote at the 2025 Annual Meeting.

SOLICITATION, VOTING AND REVOCABILITY OF PROXIES

On January 22, 2025 (the “Record Date”), there were issued and outstanding 14,386,468 shares of common stock. Only holders of common stock of record at the close of business on the Record Date are entitled to receive notice of, and to vote at, the annual meeting and any adjournment thereof. Each share of common stock is entitled to one vote on each matter submitted to shareholders. Voting is on a non-cumulative basis. Shares of our common stock represented by an effective proxy in the accompanying form will, unless contrary instructions are specified in the proxy, be voted:

•FOR the election of the seven (7) directors nominated by the Board and named in this proxy statement;

•FOR the resolution approving, by non-binding vote, the compensation of the named executive officers, as disclosed in this proxy statement pursuant to the compensation disclosure rules of the SEC;

•FOR the recommendation, by non-binding vote, of every year as the frequency of future advisory votes on executive compensation;

•FOR the approval of the DLH Holdings Corp. 2025 Equity Incentive Plan;

•FOR the ratification of WithumSmith+Brown, PC as our independent registered public accounting firm for the fiscal year ending September 30, 2025; and

•FOR such other matters as may be properly brought before the meeting, and any adjournment or postponement thereof, and for which the persons named on the enclosed proxies determine, in their sole discretion, to vote in favor.

INTERNET AVAILABILITY OF PROXY MATERIALS

We are furnishing proxy materials to our shareholders primarily via the Internet, instead of mailing printed copies of those materials to each shareholder. On or about January 28, 2025, we mailed to our shareholders (other than those who previously requested electronic delivery) a Notice of Internet Availability containing instructions on how to access our proxy materials, including our proxy statement and our annual report. The Notice of Internet Availability also instructs our shareholders on how to access their proxy card to vote through the Internet or by smartphone or tablet. This

26063747v.1

process is designed to expedite shareholders’ receipt of proxy materials, lower the cost of the annual meeting, and help conserve natural resources. However, if a shareholder would prefer to receive printed proxy materials, the shareholder may follow the instructions included in the Notice of Internet Availability. If a shareholder has previously elected to receive our proxy materials electronically, that shareholder will continue to receive these materials via e-mail unless he or she elects otherwise.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Shareholders on March 13, 2025. The Proxy Statement and our 2024 Annual Report to Shareholders are available at:

https://www.cstproxy.com/dlhcorp/2025

MEETING FORMAT

We are committed to ensuring that our shareholders have the same rights and opportunities to participate in the 2025 annual meeting regardless of whether they choose to participate remotely via the Internet or in person. To that end, shareholders will have the ability to attend the 2025 annual meeting, vote their shares electronically, and ask questions at the meeting, as discussed further below.

Shareholders attending virtually will have an opportunity to submit written questions via the Internet at any time during the meeting by following the instructions that will be available on the meeting website.

How to Vote at the 2025 Annual Meeting

Voting at the 2025 Annual Meeting

If you are a stockholder of record and choose to vote in person, you can attend the annual meeting and cast your vote at the 2025 Annual Meeting. Shareholders may also cast their votes online at the meeting by following the instructions at https://www.cstproxy.com/dlhcorp/2025 and using the control number assigned by Continental Stock Transfer & Trust Company. Shareholders who hold their shares through a broker, bank or nominee and wish to vote at the meeting must present at the meeting a legal proxy from the broker, bank or nominee issued in the shareholder’s name and confirming their beneficial ownership of the shares to be voted. Whether or not a shareholder plans to attend the meeting, the shareholder should vote by proxy to ensure his or her vote is counted. A shareholder may still attend the meeting in person and vote if he or she has already voted by proxy.

Voting by Proxy - Shareholders of Record

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered a “shareholder of record” and you may vote in person by attending the meeting, or by voting your shares by proxy over the internet or by smartphone or tablet by following the instructions provided in the Notice of Internet Availability, or, if you requested to receive printed proxy materials, you may vote by marking, dating and signing the proxy card delivered to you and returning it in the postage-paid envelope provided, or you may vote over the internet or by smartphone or tablet pursuant to the instructions provided in the proxy card. Instructions for voting via the internet, by smartphone or tablet and by mail are summarized below.

26063747v.1

By Internet-If you have internet access, you may submit your proxy by following the “Vote by Internet” instructions on the Notice of Internet Availability.

By Smartphone or Tablet-You may submit your proxy via smartphone or tablet by following the “Mobile Voting” instructions on the Notice of Internet Availability.

By Mail-You may request delivery of a physical proxy card and submit your proxy by signing your proxy card and mailing it in the postage-prepaid envelope provided to you.

In order to be timely processed, all proxies submitted by record holders through the Internet, smartphone or tablet, or by telephone must be received by 11:59 p.m. Eastern Time on March 12, 2025.

If you are a shareholder of record, your shares will be voted in the manner that you indicate in your proxy card or via the Internet or by smartphone or tablet. If you return a signed proxy card but do not indicate how you wish to vote your shares, your shares will be voted:

•FOR the election of the seven (7) directors nominated by our Board of Directors and named in this proxy statement (Proposal 1);

•FOR the approval, by non-binding vote, of the compensation of our named executive officers (Proposal 2);

•FOR the recommendation, by non-binding vote, of every year as the frequency with which shareholders will have an advisory vote on executive compensation (PROPOSAL 3);

•FOR the approval of the DLH Holdings Corp. 2025 Equity Incentive Plan (PROPOSAL 4); and

•FOR the ratification of WithumSmith+Brown, PC as our independent registered public accounting firm for fiscal 2025 (Proposal 5).

If any other business properly comes before the shareholders for a vote at the annual meeting, or at any adjournments or any postponements of the meeting, your shares will be voted according to the discretion of the holders of the proxy.

Voting by Proxy - Shares Held in Street Name

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in “street name.” Most beneficial owners whose stock is held in the name of a broker, bank or other nominee receive instructions for granting proxies from their brokers, banks or nominees, rather than our proxy card. Shareholders owning shares through certain brokers, banks and nominees are typically able to vote by telephone, mobile devices or over the internet. You can vote your shares held through a broker, bank or nominee by following the voting instructions sent to you by that institution. If Internet, telephone or mobile device voting is unavailable from your bank or brokerage firm, please complete and return the enclosed voting instruction card in the addressed, postage paid envelope provided. If you provide specific voting instructions, your shares will be voted as you instruct. If you sign but do not provide instructions, your shares will be voted as described below. If you hold your shares in “street name” through a broker or other nominee, then the broker who holds your shares has the authority under the applicable stock exchange rules to vote on certain items when they have not received instructions from you. However, if you hold your shares in street name you must cast your vote if you want it to count for proposals 1 through 4; no votes will be cast on your behalf on such proposals if you hold your shares in street name and you do not instruct your bank or broker how to vote. Your bank or broker will, however, continue to have discretion to vote any uninstructed shares on the ratification of the appointment of the Company’s independent registered public accounting firm (proposal 5 of this proxy statement).

26063747v.1

Quorum

Under our bylaws, the presence, either in person or by proxy, of the holders of a majority of the outstanding shares of the Company’s common stock is necessary to constitute a quorum permitting action to be taken at the Annual Meeting. Shares are counted as present at the meeting if you are present in person at the meeting, or if you have properly submitted a proxy. In addition, abstentions and broker non-votes are counted as present at the Annual Meeting for the purpose of determining the presence of a quorum.

Vote required

Proposal 1. The shareholders will vote to elect seven (7) directors to serve until the Company’s 2026 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified or until their earlier death, resignation or removal. The election of directors requires a plurality of the votes cast by the holders of the Company’s common stock present and voting at the Annual Meeting, with the seven (7) nominees receiving the highest vote totals to be elected. Shareholders may vote “FOR” OR “WITHHOLD AUTHORITY.” Because directors need only be elected by a plurality of the vote, in an uncontested election broker non-votes and withhold votes will not affect whether any particular nominee has received sufficient votes to be elected in such cases. If your shares are held by your broker in “street name,” and you do not furnish voting instructions to your broker, your brokerage firm may not vote your shares on Proposal 1. Brokerage firms and nominees will not have the authority to vote their customers’ unvoted shares on Proposal 1 if the customers have not furnished voting instructions within a specified period of time prior to the Annual Meeting.

Proposal 2. To approve Proposal 2, we must receive the affirmative vote of at least a majority of the votes cast at the Annual Meeting by our shareholders. For Proposal 2, a shareholder may indicate “FOR,” “AGAINST” OR “ABSTAIN” on the proxy card. For purposes of determining the number of votes cast with respect to Proposal 2, only those votes cast “FOR” OR “AGAINST” are included. Abstentions and broker non-votes are counted only for purposes of determining whether a quorum is present at the meeting and therefore will have no effect on the outcome of the vote for this proposal. This vote is advisory only and not binding on the Company. Although this is advisory, we, our Board of Directors, and the Management Resources and Compensation Committee of the Board value the opinions of our shareholders and expect to take the outcome of this vote into account when considering future compensation arrangements for our executive officers. Brokerage firms and nominees will not have the authority to vote their customers’ unvoted shares on Proposal 2 or to vote their customers’ shares if the customers have not furnished voting instructions within a specified period of time prior to the Annual Meeting.

Proposal 3. With respect to Proposal 3, the approval of the frequency of the advisory vote on executive compensation requires the favorable vote of a majority of votes cast unless none of the three frequency choices receives a majority, in which case the choice that receives the plurality of votes cast will be considered approved. For Proposal 3, the proxy card provides spaces for a shareholder to vote for the option of every one year, two years or three years as the frequency with which shareholders will have an advisory vote on executive compensation, or to abstain. Abstentions and broker non-votes are counted only for purposes of determining whether a quorum is present at the meeting and therefore will have no effect on the outcome of the vote for this proposal. If none of the three frequency options receives the vote of the holders of a majority of the votes cast, we will consider the frequency option (one year, two years or three years) receiving the highest number of votes cast by shareholders to be the frequency that has been recommended by shareholders. This vote is advisory only and not binding on the Company. The Board of Directors may decide that it is in the best interest of our shareholders and the Company to hold future executive compensation advisory votes more or less frequently, but will in no case hold them less frequently than every three years.

Proposal 4. To approve Proposal 4, the approval of the DLH Holdings Corp. 2025 Equity Incentive Plan, we must receive the affirmative vote of at least a majority of the votes cast at the Annual Meeting by our shareholders. For Proposal 4, a shareholder may indicate “FOR,” “AGAINST” OR “ABSTAIN” on the proxy card. For purposes of

26063747v.1

determining the number of votes cast with respect to this proposal, only those votes cast “FOR” OR “AGAINST” are included. Abstentions and broker non-votes are counted only for purposes of determining whether a quorum is present at the meeting and therefore will have no effect on the outcome of the vote for this proposal. If your shares are held by your broker in “street name,” and you do not vote your shares, your brokerage firm cannot vote your unvoted shares on Proposal 4.

Proposal 5. To approve Proposal 5, the ratification of the appointment of WithumSmith+Brown, PC as our independent registered public accounting firm for fiscal 2025, we must receive the affirmative vote of at least a majority of the votes cast at the Annual Meeting by our shareholders. For Proposal 5, a shareholder may indicate “FOR,” “AGAINST,” OR “ABSTAIN” on the proxy card. For purposes of determining the number of votes cast with respect to this proposal, only those votes cast “FOR” OR “AGAINST” are included. Abstentions and broker non-votes are counted only for purposes of determining whether a quorum is present at the meeting and therefore will have no effect on the outcome of the vote for this proposal. Brokerage firms and nominees have the authority to vote their customers’ unvoted shares on Proposal 5 as well as to vote their customers’ shares on this proposal where the customers have not furnished voting instructions within a specified period of time prior to the Annual Meeting.

A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and has not received voting instructions from the beneficial owner. If you do not give instructions to your broker, bank, or other agent, it can vote your shares only with respect to discretionary items, but not with respect to non-discretionary items. Discretionary items are proposals considered routine under the rules of the New York Stock Exchange on which your broker, bank or other agent may vote shares held in street name in the absence of your voting instructions, and include the ratification of the selection of our independent registered public accounting firm (Proposal 5). On non-discretionary items for which you do not give instructions to your broker, bank or other agent, the shares will be treated as broker non-votes. Proposals 1 through 4 are considered non-discretionary proposals and you must give instructions to your broker, bank or other agent in order to vote your shares with respect to these proposals.

Any other matter submitted to the shareholders will require the affirmative vote of a majority of the shares represented and entitled to vote, in person or by proxy, at the Annual Meeting, unless a greater percentage is required either by law or by our amended certificate of incorporation or bylaws. In addition, the proxy confers discretionary authority to the persons named in the proxy authorizing those persons to vote, in their discretion, on any other matters properly presented at the Annual Meeting. The Board of Directors is not currently aware of any such other matters. If any other matter does properly come before the Annual Meeting, the Board of Directors intends that the persons named in the enclosed form of proxy will vote on such matter in accordance with their judgment.

Revocation of Proxies

Any proxy may be revoked at any time before it is voted at the Annual Meeting.

CORPORATE GOVERNANCE

Meetings of the Board of Directors; Independence and Committees

During the fiscal year ended September 30, 2024, the Board of Directors met on 9 occasions. No member of the Board or any committee failed to attend at least, or participated in fewer than, 75% of the meetings of the Board or of a committee on which such member serves. During all the regularly scheduled meetings in fiscal year 2024, the Board of Directors met in executive session where only the independent directors were present without any members of management.

The listing rules established by the Nasdaq Stock Market require that a majority of the members of a listed company’s board of directors qualify as “independent” as affirmatively determined by the board, meaning that each independent director has no direct or indirect material relationship with a company other than as a director and/or a shareholder. Our Board of Directors consults with legal counsel to ensure that our Board’s determination with respect to the definition of “independent” is consistent with current Nasdaq listing rules. The Nominating and Corporate Governance Committee annually reviews the independence of all directors and nominees for director, including relevant transactions or relationships between each director and nominee, or any of his or her family members or affiliates. The Nominating and Corporate Governance Committee reports its findings to the full Board. Based on the foregoing, including the information set forth below under the caption “Certain Relationships and Related Transactions”, the Board has affirmatively determined that each of our current directors, other than Zachary C. Parker, who serves as our President and Chief Executive Officer, are independent directors under the applicable guidelines noted above. As a result, each of Ms. Bjornaas, Dr. Granger, Dr. Murphy, Mr. Wasserman, Mr. Yerks, and Mr. Zelkowicz is deemed to be “independent” as that term is defined under the rules of the Nasdaq Stock Market.

The Board of Directors currently has four (4) committees: the Audit Committee, the Management Resources and Compensation Committee, the Nominating and Corporate Governance Committee, and the Cyber, Technology and Biomedical Research Committee. All of the members of our Audit, Nominating and Corporate Governance and Management Resources and Compensation Committees meet the standards for independence required under current Nasdaq Stock Market listing rules, SEC rules, and applicable securities laws and regulations. Further, the members of the Cyber, Technology and Biomedical Research Committee are also independent. Each of these committees has a written charter approved by the Board of Directors.

Corporate Governance

Board Leadership Structure

We have separated the positions of chairman of the board and chief executive officer consistent with the view of the Board that such a structure is the most appropriate for us based on the size of the Board as well as the experience of the applicable individuals, the current business environment of our Company or other relevant factors. Further, the Board believes that the separation of the positions of chief executive officer and chairman of the board strengthens its governance structure, fosters clear accountability and enhances alignment on corporate strategy. We will continue to review this structure from time to time in accordance with the needs of the Company.

26063747v.1

Board’s Role in Oversight of Risk

The Board of Directors does not have a separate risk oversight body but rather manages risk directly and through its committees. In particular, the Board of Directors meets regularly with and is updated by our executive officers on areas of material risk to the Company, including strategic planning and financial, regulatory, legal and operational updates. These reports are provided in connection with every regular Board meeting and are discussed, as necessary, at the meeting. The Board of Directors is also routinely informed of developments that affect our risk profile and those that are material to other aspects of our business. Further, significant transactions and decisions require approval by the Board of Directors, or the appropriate Board committee. The Board of Directors mitigates risks through discussing with management the appropriate level of risk for the Company and evaluating the risk information received from management. These risks include financial, technological, competitive, and operational risks.

Further, the Audit Committee receives updates from senior management and assesses risk in satisfaction of their risk management role in accordance with the Audit Committee charter. Our Audit Committee charter provides that the Audit Committee is responsible for monitoring material financial and operating risks of the Company, including monitoring of our internal control over financial reporting and disclosure controls and procedures. On a quarterly basis, management reports to the Audit Committee regarding our various risk areas. The Audit Committee meets regularly with management and our independent registered public accounting firm and addresses risks as the Audit Committee deems appropriate. In addition, each of the other committees of the Board of Directors considers risks within its area of responsibility, as follows. Our Management Resources and Compensation Committee considers risks associated with our compensation policies and practices, with respect to both executive compensation and compensation generally. The Management Resources and Compensation Committee’s responsibilities include annually reviewing and approving corporate goals and objectives relevant to our Chief Executive Officer’s and our other executive officers’ compensation, making recommendations with respect to the compensation of our executive officers, and reviewing our compensation policies and procedures in general. The Nominating and Corporate Governance Committee oversees risks associated with governance, corporate responsibility and other ESG risks, including, the independence of the Board and potential conflicts of interest. The Cyber, Technology and Biomedical Research Committee was established to assist the Board in overseeing the company’s risk posture as it relates to technology development and application activities and information security and related exposures. As a government contractor and a provider of information technology services, we are entrusted with highly sensitive information, and must implement safeguards to withstand unauthorized attempts to compromise this information through cyberattacks and other information security risks. Management provides our Board and this Committee with regular updates about our cybersecurity and related risk exposures, our policies and procedures to mitigate such exposures and the status of projects to strengthen our information security infrastructure and defend against and respond to threats. We also conduct periodic assessments to test our cybersecurity controls and continually evaluate our policies and procedures regarding our handling and control of personal data and the systems we have in place to help protect us from cybersecurity or personal data breaches.

Nominating Matters

Our Nominating and Corporate Governance Committee considers candidates for election to our Board of Directors, whether recommended by security holders or otherwise, in accordance with the following criteria. The Nominating and Corporate Governance Committee applies the following general criteria to all candidates:

•Nominees shall have a reputation for integrity, honesty and adherence to high ethical standards.

26063747v.1

•Nominees should have demonstrated business acumen, experience and the ability to exercise sound judgment in matters that relate to current and long-term objectives of the Company and should be willing and able to contribute positively to our decision making process.

•Nominees should have a commitment to understand the Company and its industries and to regularly attend and participate in meetings of the Board and its committees.

•Nominees should have the interest and ability to understand the sometimes conflicting interests of various constituencies of the Company, which include shareholders, employees, customers, governmental units, creditors and the general public, and to act in the interests of all shareholders.

•Nominees should not have, nor appear to have, a conflict of interest that would impair the nominees’ ability to represent the interests of all the Company’s shareholders and to fulfill the responsibilities of a director.

•Nominees shall not be discriminated against on the basis of race, religion, national origin, sex, disability or any other basis proscribed by applicable law.

The re-nomination of existing directors is not to be viewed as automatic, but is based on continuing qualification under the various criteria set forth above. In addition, the Nominating and Corporate Governance Committee considers the existing director’s performance on the Board and any committee thereof. The Nominating and Corporate Governance Committee also considers the backgrounds and qualifications of the directors considered as a group. Although the Company does not have a formal policy with regard to the consideration of diversity in identifying nominees, the Nominating and Corporate Governance Committee will consider whether the candidate assists in achieving a mix of members that represents a diversity of background and experience, including with respect to age, gender, international background, race and specialized experience. Accordingly, the Nominating and Corporate Governance Committee strives to ensure that the Board, when taken as a whole, provides a significant breadth of experience, knowledge and abilities that shall assist the Board in fulfilling its responsibilities. Nominees for the Board of Directors should be committed to enhancing long-term shareholder value and must possess a high level of personal and professional ethics, sound business judgment and integrity. The Nominating and Corporate Governance Committee may from time to time review the appropriate skills and characteristics required of Board members, including such factors as business experience, diversity, personal skills in finance, marketing, international business, financial reporting and other areas that are expected to contribute to an effective Board of Directors. In evaluating potential candidates for the Board of Directors, the Nominating and Corporate Governance Committee considers these factors in the light of the specific needs of the Board of Directors at that time. All of the nominees are current DLH directors standing for reelection.

Procedure to be Followed by Shareholders in Submitting Director Candidate Recommendations

Any shareholder who desires the Nominating and Corporate Governance Committee to consider one or more candidates for nomination as a director should, either by personal delivery or by United States mail, postage prepaid, deliver a written recommendation addressed to the Secretary of the Company at our principal executive offices not later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the anniversary date of the immediately preceding annual meeting; provided, however, that, in the event that the date of the annual meeting is advanced more than 30 days prior to or delayed (other than as a result of adjournment) by more than 30 days after the anniversary of the preceding year’s annual meeting, notice by the shareholder to be timely must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the date on which such notice of the date of such meeting was mailed a public announcement of the date of such meeting was first made by the Company.

Each written recommendation should set forth: (a) the name and address of the shareholder making the recommendation and of the person or persons recommended; (b) the consent of such person(s) to serve as a director(s) of the Company if nominated and elected; and (c) a description of how the person(s) satisfy the general criteria specified in our Amended and Restated By-laws for consideration as a candidate.

Additional Criteria for Notice of Shareholder Nominees

In accordance with our Amended and Restated By-Laws, any shareholder entitled to vote in the election of directors generally may nominate one or more persons for election as directors at a meeting only if written notice of such shareholder’s intent to make such nomination or nominations has been given, either by personal delivery or by United States mail, postage prepaid, to the Secretary of the Company in accordance with the terms described in the preceding paragraph. Each shareholder’s notice shall set forth for each nominee all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors pursuant to Regulation 14A under the Securities Exchange Act of 1934 and pursuant to the Company’s Amended and Restated By-laws, including such person’s written consent to being named as a nominee and to serving as a director if elected, as well as whether and the extent to which any hedging or other transaction or series of transactions has been entered into by or on behalf of the nominee with respect to any securities of the Company and a description of all arrangements or understandings between the shareholder and each nominee and any other person or persons (naming such person or persons) pursuant to which the nominations are to be made by the shareholder. Further, the notice shall include as to the shareholder giving notice all information required to be disclosed by the shareholder under Regulation 14A under the Exchange Act, including: (i) the name and address of the shareholder; (ii) the class or series and number of shares of the Company which are, directly or indirectly, owned by such shareholder, as well as any derivative positions held by such shareholder; (iii) any proxy, arrangement, or relationship pursuant to which such shareholder has a right, directly or indirectly, to vote any shares of any security of the Company; (iv) any hedging or similar transactions in securities of the Company directly or indirectly owned by such shareholder; (v) a description of any agreement, arrangement or understanding with respect to the proposal; and (vi) a statement whether either such shareholder intends, or is part of a group which intends, to deliver a proxy statement and form of proxy to holders of at least the percentage of the Company’s voting shares required under applicable law to carry the proposal.

Shareholder Communications with the Board

Any shareholder may communicate with the Board of Directors in writing through the Company’s Corporate Secretary provided that the communication identifies the shareholder and the number and type of securities held by that shareholder. The Secretary reviews such communications, and forwards them to the Board of Directors unless the Secretary, in consultation with the Chief Executive Officer, determines that the communication is inappropriate for the Board’s consideration (for example, if it relates to a personal grievance or is unrelated to Company business). The Secretary maintains a permanent written record of all such shareholder communications received by the Secretary. This process was unanimously approved by the Nominating and Corporate Governance Committee of the Board of Directors (which is comprised of independent directors).

Attendance at Annual Meetings

All of the nominees for directors being voted upon at the annual meeting are directors standing for re-election. Except in the event of unexpected or unusual circumstances, all nominees and other directors are expected to be present at the annual meeting of shareholders. During the annual meeting of shareholders held on March 14, 2024, all of our then current directors were in attendance.

26063747v.1

Management Resources and Compensation Committee Interlocks

Dr. Frances M. Murphy, Dr. Elder Granger, Mr. Austin J. Yerks III and Mr. Stephen J. Zelkowicz served on the Management Resources and Compensation Committee as of the end of the fiscal year ended September 30, 2024. There are no interlocks between our directors and directors of other companies.

Code of Ethics and Business Conduct

We have adopted a written code of business conduct and ethics, which applies to our principal executive officer, principal financial or accounting officer or person serving similar functions and all of our other employees and members of our Board of Directors. Our Code of Ethics can be found posted on our Corporate Governance web page at www.dlhcorp.com and provides employees with a confidential method of reporting suspected violations. A printed copy is available, without charge, to any shareholder upon written request to the Secretary of the Company, at addressed to the Company’s headquarters at 3565 Piedmont Road, NE, Bldg. 3, Suite 700, Atlanta, GA 30305. Any amendment or waiver of our code of ethics required to be disclosed under the Exchange Act will be reflected on our corporate website.

Insider Trading Policy

The Company has an Insider Trading Policy, which governs the purchase, sale and other dispositions of its securities by directors, officers and employees and affiliates of the Company, as well as their immediate family members and other persons living in their households. The Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations and any listing standards applicable to the Company. The Insider Trading Policy prohibits covered persons from directly or indirectly purchasing or selling the Company’s securities while in possession of material non-public information concerning the Company, except in the limited circumstances described in the policy. Additionally, the Company’s personnel are prohibited from engaging in hedging transactions with respect to the Company’s securities of the Company. The Insider Trading Policy requires pre-approval of any transaction related to the Company’s securities by the Company’s executive officers and directors.

Compensation Recovery Policy

We have adopted a compensation recovery policy (the “Clawback Policy”) in accordance with the listing standards and rules of the Nasdaq Stock Market, that requires the Board to recoup excess compensation paid to our executive officers as a result of a financial statement restatement, regardless of any misconduct, fault or illegal activity on the part of the executive officer. The Clawback Policy applies in the case of an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws. The Clawback Policy applies to all incentive-based compensation, which is any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure, received by our executive officers.

Anti-Hedging and Anti-Pledging Policies

The Company’s Insider Trading Policy prohibits directors, officers and key employees from selling short or purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds), or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of DLH’s securities. It also prohibits those parties from pledging DLH securities.

26063747v.1

Equity Grant Practices

Although we have not adopted a formal policy pertaining to the timing of stock option grants to our named executive officers, it is our practice not to time the grant of equity awards, including stock options, in relation to the release of material non-public information. Similarly, the Company does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. Although the Company has not recently granted stock options to its named executive officers except upon a hiring decision, the Compensation Committee generally approves the grant of annual equity awards for the Company’s executive officers, including each of the named executive officers, in December of each year. In special circumstances, including the hiring or promotion of an individual or where the Compensation Committee determines it is in the best interest of the Company, the Compensation Committee may approve grants of equity awards at other times.

Board Stock Ownership Guidelines

The Board believes that its members should be incentivized to focus on the Company’s long-term shareholder value. As such, the Board has adopted a Board member stock ownership policy establishing, as a guideline, that non-employee members of the Board are expected to own shares of Company common stock valued at five (5) times such director’s annual cash retainer for Board service, which may include shares of restricted stock granted as part of our Board compensation program. Such ownership level is to be achieved over a period of five (5) years after becoming a member of the Board or five (5) years from the adoption of these guidelines. The guidelines provide that directors are expected to maintain this ownership level for as long as such person remains a non-employee director. As of the Record Date, each of our non-employee directors either met these stock ownership guidelines or is expected to meet the ownership guidelines within the specified time period.

Certain Relationships and Related Transactions

Except as disclosed herein, we have not entered into any material transactions or series of similar transactions with any director, executive officer or any security holder owning five percent or more of our common stock since the beginning of our last fiscal year. For information concerning employment agreements with, and compensation of, our executive officers and directors, see the disclosure in the section of this proxy statement captioned “Executive Compensation and Related Information.” Although we have not adopted a formal policy relating to the approval of proposed transactions that we may enter into with any of our executive officers, directors and principal shareholders, including their immediate family members and affiliates, our Audit Committee, all of the members of which are independent, reviews the terms of any and all such proposed material related party transactions. The results of this review are then communicated to the entire Board of Directors, which has the ultimate authority as to whether or not we enter into such transactions. We will not enter into any material related party transaction without the approval of our Audit Committee and our Board of Directors. In approving or rejecting the proposed related party transaction, our Audit Committee and our Board of Directors shall consider the relevant facts and circumstances available and deemed relevant to them, including, but not limited to the risks, costs and benefits to us, the terms of the transaction, the availability of other sources for comparable services or products, and, if applicable, the impact on a director’s independence. We shall approve only those agreements that, in light of known circumstances, are in, or are not inconsistent with, our best interests, as our Audit Committee and our Board of Directors determine in the good faith exercise of their discretion.

Noah Wasserman, a non-executive employee of the Company, is the son of Frederick G. Wasserman, the current Chair of the Board. During the 2023 fiscal year, his base salary and other compensation was less than $120,000. Effective December 1, 2024, his base salary was increased to approximately $150,000 per annum in recognition of his performance and expanded responsibilities. Mr. Wasserman also participates in the Company’s other benefit programs on the same basis as other employees at the same level.

26063747v.1

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors and executive officers, and persons who own, directly or indirectly, more than 10% of a registered class of our equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities we issue. Officers, directors and greater than 10% shareholders are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file. Based solely on a review of the copies of such reports filed with the SEC and of written representations by certain officers and directors, we believe that all persons subject to the reporting requirements of Section 16(a) filed the required reports on a timely basis during the fiscal year ended September 30, 2024, except that one Form 4 filed on July 18, 2024 reporting a gift of 6,544 shares by one of our directors, Martin J. Delaney, was not timely filed due to administrative oversight.

Procedures for Determining Executive and Director Compensation

As described above, the Compensation Committee, among other things, assists our Board of Directors in the discharge of its responsibilities with respect to compensation of our executive officers and non-employee directors. In accordance with its charter, the Compensation Committee has the following duties and responsibilities:

•To determine the amount, form and terms of compensation of our Chief Executive Officer and other executive officers, and to take such action, and to direct us to take such action, as it deems necessary or advisable to compensate our Chief Executive Officer and other executive officers in a manner consistent with its determinations, and shall deliberate and vote on all such actions outside the presence of our Chief Executive Officer and other officers.

•To review, at least annually, the performance of our Chief Executive Officer and other executive officers, giving consideration to goals and objectives established for such performance, and, in light of such review, determining each officer’s compensation.

•In accordance with its charter, the Compensation Committee has authority to establish our general compensation policies and practices and to administer plans and arrangements established pursuant to such policies and practices.

•In addition, it has authority to administer our equity compensation programs, including without limitation to recommend the adoption of such plans, to recommend the reservation of shares of our common stock for issuance thereunder, to amend and interpret such plans and the awards and agreements issued pursuant thereto, and to make awards to eligible persons under the plans and determine the terms of such awards, including any such awards to our Chief Executive Officer and other officers.

•With respect to non-employee director compensation, the Compensation Committee reviews such compensation practices and policies and makes recommendations to our Board of Directors as to the amount, form and terms of non-employee director compensation.

In determining its compensation programs and making compensation decisions for our executives, the Compensation Committee, from time to time, reviews general information regarding the compensation practices of other companies, including some that may compete with us for the services of its executives and employees and that information is a factor used by the Compensation Committee in its decisions and in its general oversight of compensation practices. In addition, in developing its understanding of the Company’s position within the marketplace for management talent and to assist it in making decisions to enable us to attract and retain a strong management team, the Compensation Committee reviews national compensation survey data, peer financial performance and compensation information, the Company’s financial performance both against its internal financial targets and its designated peer group, and internal

26063747v.1

compensation comparability among senior executives. However, it does not use that information to generate specific compensation amounts or targets. Instead, in each compensation decision, the committee exercises its business judgment regarding the appropriateness of types and amounts of compensation in light of the value to the company of specific individuals.

During fiscal 2023, the Compensation Committee retained Korn Ferry International (“Korn Ferry”), an independent consulting firm, to assist it in its evaluation of compensation decisions for the 2024 fiscal year. Korn Ferry conducted analyses and provided information to the Compensation Committee to assist it in determining whether the Company’s executive compensation programs are reasonable and consistent with competitive practices. The Compensation Committee considered these analyses along with its independent assessment of general market data, as it determined the compensation arrangements for our named executive officers and non-employee directors for fiscal 2024. In addition, the Compensation Committee reviewed the independence of Korn Ferry in light of SEC rules and concluded that its work for the Compensation Committee was independent and did not raise any conflict of interest. The Compensation Committee is directly responsible for the appointment, compensation and oversight of the compensation consultant and the Company provided appropriate funding for payment of reasonable compensation to the consultant retained by the Compensation Committee. Additional information concerning the Compensation Committee’s procedures in determining executive compensation is set forth below under the caption “Executive Compensation – Determination of Executive Compensation”.

Director Compensation

The Compensation Committee periodically evaluates the compensation and form of compensation for non-employee directors. As a part of this process, the Compensation Committee reviews general market data for director compensation as well as director compensation data from the Company’s peer group, the same group used for our executive compensation review, including cash compensation, equity compensation and stock ownership requirements. The Compensation Committee also considered input from the third-party compensation consultant it retained regarding market practices for director compensation. Generally, the Compensation Committee intends to set director compensation levels at or near the market median relative to directors at companies of comparable size, industry, and scope of operations in order to ensure directors are paid competitively for their time commitment and responsibilities. As a result, non-employee director compensation generally approximates the market median and is periodically adjusted to maintain alignment with market practices. The Compensation Committee intends to continue to conduct director compensation reviews annually. Based on the Compensation Committee’s evaluation of the compensation arrangements for our non-employee directors, including the input received from its independent compensation consultant, the Compensation Committee made no changes to the compensation arrangements for our non-employee directors for fiscal 2024. Accordingly, for the fiscal year ended September 30, 2024, our non-executive directors were compensated as follows:

•the annual fee for service on the board of directors for non-employee directors was $60,000;

•the annual fee payable to the Chairman of the Board for service in such capacity was $21,000;

•the annual fee payable to the Chair of the audit committee for service in such capacity was $18,000;

•the annual fee payable to the Chair of the compensation committee for service in such capacity was $15,000;

•the annual fee payable to the Chair of the nominating and corporate governance committee was $12,000;

•the annual fee payable to the Chair of the cyber, technology and biomedical research committee was $15,000;

26063747v.1

•an annual fee payable to members (other than the chair) of our audit committee for service on such committee of $7,500;

•an annual fee payable to members (other than the chair) of our management resources and compensation committee, nominating and corporate governance committee, and cyber, technology and biomedical research committee for service on such committees of $5,000;

•each non-executive director, other than our Chairman, was granted, under our 2016 Omnibus Equity Incentive Plan (the “2016 Plan”), restricted stock units (“RSUs”) with an aggregate value of $100,000, and our Chairman was granted a RSU with an aggregate value of $118,000. The number of RSUs to be granted are determined by reference to the fair market value of the Company’s common stock (as determined under the 2016 Plan) on the grant date. The RSUs were granted as of October 1, 2023 and entitle the holder to receive an equivalent number of shares of our common stock upon vesting. These RSUs cliff-vested on September 30, 2024. Thereafter, RSUs will be granted annually on October 1 and will vest in full on September 30 of the year following the grant date, subject to acceleration as described below. Generally, upon termination of a director’s Board membership, all unvested RSUs are forfeited. However, the vesting of any unvested RSUs will accelerate upon a director’s death or disability or upon the occurrence of a change in control (as defined in the 2016 Plan); and

•reasonable and customary expenses incurred in attending Board and committee meetings are reimbursable.

“Stock Awards” reflect the portion of restricted stock grants awarded to non-employee directors under the Company’s 2016 Omnibus Equity Incentive Plan that was recognized by the Company as a compensation expense in fiscal year 2024 in accordance with FASB Accounting Standards Codification Topic 718: Compensation-Stock Compensation. The grant date fair value per share is the closing price for the Company’s stock on the grant date. A discussion of the methods used to calculate these values may be found in the Notes to Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended September 30, 2024. On October 1, 2023, we granted 8,569 RSUs to each of our non-executive directors and 10,111 RSUs to the chairman of our

26063747v.1

board. The closing price of our common stock on September 29, 2023, the most recent trading day prior to the grant date was $11.67. As of September 30, 2024, the outstanding number of restricted stock awards and shares issued under RSU grants beneficially owned by our non-employee directors was: Ms. Bjornaas - 8,569; Mr. Delaney - 203,703; Dr. Granger – 117,727; Dr. Murphy – 107,960; Mr. Wasserman - 196,153; Mr. Yerks – 152,960; and Mr. Zelkowicz - 32,935. Excludes RSUs granted to our non-executive directors on October 1, 2024. On such date we granted a total of 78,556 RSUs to our non-executive directors as follows: Ms. Bjornaas - 10,941; Mr. Delaney - 10,941; Dr. Granger - 10,941; Dr. Murphy – 10,941; Mr. Wasserman - 12,910; Mr. Yerks – 10,941; and Mr. Zelkowicz - 10,941. Such RSUs were granted under the 2016 Plan, will cliff-vest on September 30, 2025, and are otherwise on terms substantially similar to the RSUs granted October 1, 2023.

Board Diversity

In August 2021, the SEC approved a Nasdaq Stock Market proposal to adopt new listing rules relating to board diversity and disclosure. The Nasdaq diversity rule required all Nasdaq listed companies to disclose consistent, transparent diversity statistics regarding their boards of directors. However, in December 2024, the U.S. Court of Appeals for the Fifth Circuit vacated the order approved by the SEC adopting the Nasdaq diversity rule. Accordingly, we are no longer required by such rule to have, or explain why we do not have, at least two diverse directors, including one who self-identifies as female and one who self-identifies as either an under-represented minority or LGBTQ+. However for the 2025 Annual Meeting, we have decided to continue to include the Board Diversity Matrix and related disclosures in the form that was prescribed by Nasdaq. In this regard, the following chart summarizes certain self-identified personal characteristics of our directors as of the date indicated.


Board Diversity Matrix (as of January 28, 2025)

Report of the Audit Committee of the Board of Directors

The Audit Committee is comprised solely of independent directors, as defined in the Marketplace Rules of The Nasdaq Stock Market, and operates under a written charter. Management has the primary responsibility for the financial statements and the reporting process, including internal control systems. Our independent registered public accounting firm, WithumSmith+Brown, PC, is responsible for expressing an opinion as to the conformity of our audited financial statements with United States generally accepted accounting principles and rendering an opinion on the effectiveness of our internal control over financial reporting. In fulfilling its oversight responsibilities, the Audit Committee:

			The Audit Committee:
			Judith L. Bjornaas, Chair, Martin J. Delaney, Frederick Wasserman, and Stephen J. Zelkowicz

The presentation of this report of the Audit Committee does not constitute “soliciting material” and should not be deemed “filed” with the SEC or incorporated by reference into any other filing by us under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof, except to the extent we specifically incorporate this report by reference therein.

Vote Required and Board Recommendation

The election of directors requires a plurality of the votes cast at the Annual Meeting. “Plurality” means that the nominees who receive the largest number of votes cast “for” such nominee are elected as directors. As a result, the seven (7) nominees receiving the most "FOR" votes will be elected. The Board of Directors recommends that you vote FOR the seven (7) nominees for election to the Board of Directors as described in this Proposal 1.

PROPOSAL 2

ADVISORY VOTE ON EXECUTIVE COMPENSATION

We are providing our shareholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with the SEC’s rules. This proposal, which is commonly referred to as “say-on-pay,” is required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, which added Section 14A to the Securities and Exchange Act of 1934, as amended (the “Exchange Act”).

Our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. Under these programs, our named executive officers are rewarded for the achievement of our near-term and longer-term financial and strategic goals and for driving corporate financial performance and stability. The programs contain elements of cash and equity-based compensation and are designed to align the interests of our executives with those of our shareholders.

The “Executive Compensation” section of this proxy statement describes in detail our executive compensation programs and the decisions made by the Management Resources and Compensation Committee with respect to the fiscal year ended September 30, 2024. As we describe in this section of the proxy statement, our executive compensation program incorporates a pay-for-performance philosophy that supports our business strategy and aligns the interests of our executives with our shareholders. The Board believes this link between compensation and the achievement of our near- and long-term business goals has helped drive our performance over time. At the same time, we believe our program does not encourage excessive risk-taking by management.

Our Board of Directors is asking shareholders to approve a non-binding advisory vote on the following resolution:

RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the

26063747v.1

disclosure under “Executive Compensation”, the compensation tables and accompanying narrative disclosure, and any related material disclosed in this proxy statement, is hereby approved.

As an advisory vote, this proposal is not binding. The outcome of this advisory vote will not overrule any decision by the Company or the Board of Directors (or any committee thereof), create or imply any change to the fiduciary duties of the Company or the Board of Directors (or any committee thereof), or create or imply any additional fiduciary duties for the Company or the Board of Directors (or any committee thereof). However, our Management Resources and Compensation Committee and Board of Directors value the opinions expressed by our shareholders in their vote on this proposal and will consider the outcome of the vote when making future compensation decisions for named executive officers.

Section 14A of the Exchange Act also requires that shareholders have the opportunity, at least once every six years, to cast an advisory vote with respect to whether future executive compensation advisory votes will be held every one, two, or three years. At our Annual Meeting of Shareholders held on March 21, 2019, our shareholders indicated their preference for an advisory vote on the compensation of our named executive officers to be held annually, which annual frequency was also the recommendation of our Board. Our Board confirmed that we will hold an advisory vote on the compensation of our named executive officers on an annual basis until the next required vote on the frequency of such advisory votes, or until the Board otherwise determines that a different frequency for such votes is in the best interests of our shareholders.

Vote Required and Board Recommendation

On this non-binding matter, the affirmative vote of at least a majority of the votes cast at the annual meeting is required to approve this Proposal 2. The Board of Directors believes that voting FOR the compensation of our named executive officers is in the best interest of the Company and the best interests of our shareholders, and therefore, recommends a vote FOR this proposal.

PROPOSAL NO. 3

ADVISORY VOTE ON THE FREQUENCY OF FUTURE EXECUTIVE

COMPENSATION ADVISORY VOTES

In addition to providing our shareholders the opportunity to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers, in this Proposal No. 3, we are asking our shareholders to cast a non-binding advisory vote regarding the frequency of future executive compensation advisory votes. Shareholders may vote for a frequency of every one, two, or three years, or may abstain.

The Board of Directors will take into consideration the outcome of this vote in making a determination about the frequency of future executive compensation advisory votes. However, because this vote is advisory and non-binding, the Board of Directors may decide that it is in the best interests of our shareholders and the Company to hold the advisory vote to approve executive compensation more or less frequently, but no less frequently than once every three years, as required by the Dodd-Frank Act. In the future, we will propose an advisory vote on the frequency of the executive compensation advisory vote at least once every six calendar years as required by the Dodd-Frank Act.

Since 2013, we have held annual advisory votes on executive compensation, consistent with the vote of our shareholders. After careful consideration, the Board of Directors believes that an executive compensation advisory vote should be held every year, and therefore our Board of Directors recommends that you vote for a frequency of every One Year for future executive compensation advisory votes. The Board of Directors believes that an annual executive compensation advisory vote will facilitate more direct shareholder input about executive compensation. An annual

26063747v.1

executive compensation advisory vote is consistent with our policy of reviewing our compensation program annually, as well as seeking frequent input from our shareholders on corporate governance and executive compensation matters. We continue to believe an annual vote would be the best governance practice for our Company at this time. The proxy card provides shareholders with the opportunity to choose among four options (holding the vote once every year, every two years or every three years, or abstaining) and, therefore, shareholders will not be voting to approve or disapprove the recommendation of the Board of Directors.

Vote Required and Board Recommendation

On this non-binding matter, a shareholder may vote to set the frequency of the “say on pay” vote to occur every year, every two years, or every three years, or the shareholder may vote to abstain. The choice among those four choices that receives the highest number of votes will be deemed the choice of the shareholders. The Board of Directors believes that an annual executive compensation advisory vote is in the best interests of the Company and the best interests of our shareholders, and therefore, recommends a vote of “one year” for this proposal.

PROPOSAL 4

APPROVAL OF THE DLH HOLDINGS CORP.

2025 EQUITY INCENTIVE PLAN

At the Annual Meeting, our shareholders will be asked to consider and vote upon a proposal to adopt the 2025 Equity Incentive Plan (the “2025 Plan”) which will permit us to continue to provide stock options, restricted stock units, and other equity awards to our employees, non-employee directors and eligible consultants.

Overview

Following the recommendation of the Management Resources and Compensation Committee (the “Compensation Committee”) our board of directors approved the 2025 Plan on January 13, 2025, subject to shareholder approval. The Compensation Committee began to evaluate the adoption of a new equity-based compensation plan as the Company’s 2016 Omnibus Equity Incentive Plan (the “2016 Plan”) will expire in February 2026. In conducting its evaluation of a new equity plan, the Compensation Committee determined that the adoption of a new equity incentive plan, which continued to provide the ability for the Company to offer equity-based incentive compensation to its directors, employees, executive officers and consultants was prudent. In addition, the Compensation Committee and board wished to continue to provide a flexible equity compensation program for all potential participants. The structure and terms of the 2025 Plan is substantially similar to the 2016 Plan. The full text of the 2025 Plan incorporating the amendment is attached as Appendix A.

Following detailed discussions of the Compensation Committee, it recommended that the board of directors adopt, subject to shareholder approval, the 2025 Plan. Our board of directors thereafter adopted, subject to shareholder approval, the 2025 Plan. We are seeking shareholder approval in order to comply with the listing requirements of the Nasdaq Stock Market.

The 2016 Plan was originally approved by our shareholders in February 2016 and was previously amended effective in March 2018, and March 2021. As of the Record Date, there were 4,000,000 shares of common stock authorized for issuance pursuant to awards granted under the 2016 Plan and an aggregate of 831,554 shares of common stock available for issuance pursuant to future awards under the 2016 Plan. The Company intends to grant up to a maximum of 250,000 additional shares pursuant to awards under the 2016 Plan after the Record Date but prior to the 2025 Annual Meeting. As of the Record Date, a total of 3,168,446 shares of common stock have been granted pursuant to awards under the 2016 Plan and there were 1,869,825 total shares subject to outstanding awards, as detailed in the below table. Further, as of the Record Date, there were issued and outstanding 14,386,468 shares of common stock.

Burn rate measures our usage of shares for our stock plans as a percentage of our outstanding shares. For 2024, 2023, and 2022, our burn rate was (0.81)%, 2.92%, and 2.51%, respectively, resulting in an average annual burn rate of 1.54% over a three-year period. The rates were calculated by dividing the number of shares subject to awards granted during the year net of forfeitures and cancellations by the weighted average number of shares outstanding during the year.

In determining the aggregate number of shares to be authorized under the 2025 Plan, the Board of Directors sought to provide that the amount of shares authorized for issuance under the 2025 Plan not exceed the number of shares available for issuance under the 2016 Plan as of the date of the Annual Meeting, plus an adequate amount to enable the Company to use the 2025 for its intended purpose of attracting and retaining talent and as described below. Additionally, the Company will not grant more than 250,000 additional shares of common stock pursuant to awards under the 2016 Plan from and after the Record Date, unless its shareholders do not approve the 2025 Plan at the Annual Meeting. Accordingly, the Board of Directors determined that the maximum number of shares of common stock that would be available for awards under the 2025 Plan (subject to adjustment as described below) is 1,231,554 shares, less any shares granted under the 2016 Plan on or after the Record Date and prior to the effective date of the 2025 Plan.

No awards will be issued under the 2025 Plan unless shareholders approve it at the Annual Meeting. If approved, the 2025 Plan will replace the 2016 Plan as the Company’s vehicle for granting equity awards to its employees, directors and consultants. If the proposal to adopt the 2025 Plan is approved by our shareholders, the 2025 Plan will immediately become effective and all future equity awards granted to our employees, directors and eligible consultants will be made pursuant to the 2025 Plan and shares remaining under our existing plans will no longer be available for grants under such plans. Holders of unexercised options or unvested stock awards granted under the 2016 Plan will be able to exercise those options or realize the award benefits in accordance with the terms of such grants. If the requisite shareholder approval of the 2025 Plan is not obtained, (i) the 2016 Plan will continue in effect under its current terms, (ii) we will only be able to grant a limited number of future equity awards to eligible persons under the 2016 Plan until February 2026, and (iii) a new plan will need to be voted upon at our next annual meeting of shareholders or risk the Company having no shareholder approved equity compensation plan.

For the reasons described above, the Board believes that the approval of the 2025 Plan is in the best interests of the Company and its shareholders and recommends that shareholders approve the 2025 Plan. If the 2025 Plan is approved, we will grant equity-based compensation awards under the 2025 Plan, as summarized below.

Purposes of the Plan

We face intense competition in recruiting and retaining high quality personnel. Our success in this regard will be crucial to our ability to build and retain shareholder value. Our Board of Directors believes that equity awards, such as

26063747v.1

stock options, restricted stock, and other equity awards are a vital component of compensation packages that we can offer to attract and retain high-caliber individuals. Importantly, they also serve to ensure that our personnel’s overall compensation is tied to increases in shareholder value. Further, granting equity awards as a form of compensation allows us to manage cash resources. Our Board of Directors believes that continuing to have an adequately resourced equity incentive plan is important for the Company to achieve these purposes and that in light of the fact that the 2016 Plan will terminate in February 2026, it is necessary to propose the adoption of the 2025 Plan to the Company’s shareholders at the 2025 Annual Meeting.

The Board believes that the 2025 Plan will benefit the Company and its shareholders by allowing the Company to: (i) increase the stake of key employees and executives in the success of the Company; (ii) to align the interests of awardees under the 2025 Plan with the interests of the shareholders; (iii) to keep pace with the increase in number of Company employees due to both the Company’s internal growth and outside acquisition activities; and (iv) to aid the Company in its efforts to recruit and retain highly qualified individuals. The Board believes that the grant of awards under the 2025 Plan will not result in an unacceptable level of dilution to the interests of public shareholders.

The 2025 Plan provides for various types of equity awards, and therefore, will provide us with meaningful flexibility in rewarding our employees and those other individuals who provide significant services to us. The 2025 Plan is intended to provide qualifying persons with equity ownership in our company, thereby strengthening their commitment to our success, aligning the interests between our shareholders and such employees, directors and consultants and stimulating their efforts on our behalf, and to assist us in attracting and retaining talented personnel. Management believes that assuming approval of this proposal, the ratio of the number of shares available for future awards under the 2025 Plan, as amended, in relation to the number of outstanding shares of Common Stock would be within the range of outstanding shares ratios for comparable companies. All awards will be subject to the recommendations of management and approval of the Compensation Committee and/or Board of Directors and in compliance with the requirements of the securities laws and any exchange on which the shares of common stock may be listed or traded.

Description of the 2025 Plan

The following is a summary of the principal provisions of the 2025 Plan. This summary is qualified in its entirety by reference to the full text of the 2025 Plan, which is included as Appendix A hereto. The following awards may be granted under the 2025 Plan:


•			options to acquire shares of our common stock intended to qualify as incentive stock options, or ISOs, under Section 422(b) of the Code;
•			non-qualified stock options to acquire shares of our common stock, or NSOs;
•			stock appreciation rights;
•			shares of restricted common stock;
•			restricted stock units;
•			performance-based awards; and
•			other equity-linked awards.

Shares Reserved for Issuance. Subject to shareholder approval, the maximum number of shares of common stock that may be delivered to participants under the 2025 Plan is 1,231,554 shares, less any shares granted under the 2016 Plan on or after the Record Date and prior to the effective date (subject to the adjustment provisions described under “Adjustments upon Changes in Capitalization” below). If any shares of common stock subject to an award under the

26063747v.1

2025 Plan are forfeited, expire or are settled for cash (in whole or in part), the shares subject to the award may be used again for awards under the 2025 Plan to the extent of the forfeiture, expiration or cash settlement.

Shares of our common stock under awards made under the 2025 Plan in substitution or exchange for awards granted by a company acquired by us or a subsidiary, or with which we or a subsidiary combine, do not reduce the maximum number of shares that are available for awards under the 2025 Plan. In addition, if a company acquired by us or a subsidiary, or with which we or a subsidiary combine, has shares remaining available under a plan approved by its shareholders, the available shares (adjusted to reflect the exchange or valuation ratio in the acquisition or combination) may be used for awards under the 2025 Plan and will not reduce the maximum number of shares of our common stock that are available for awards under the 2025 Plan; provided, however, that awards using such available shares shall not be made after the date awards or grants could have been made under the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not our employees or directors prior to the acquisition or combination.

Minimum Vesting Period. All awards other than cash-based awards generally vest or become exercisable no earlier than twelve months from the date on which it was granted, except for the Compensation Committee’s discretion to provide for accelerated vesting or exercisability, including in connection with death, disability, retirement, termination of service without cause or for “good reason” or upon a change in control. However, 5% of the aggregate number of shares authorized for issuance under the 2025 Plan will not be subject to these minimum vesting requirements. Additionally, substitute awards granted in connection with awards that are assumed, converted or substituted in connection with a merger, acquisition or similar transaction and awards to non-employee directors that vest on the earlier of the one-year anniversary of the date of grant and the next annual meeting of shareholders which is at least 50 weeks after the immediately preceding year’s annual meeting are not subject to these minimum vesting requirements.

Administration. Subject to the reservation of authority by our board of directors to administer the 2025 Plan and act as the committee thereunder, the 2025 Plan will be administered by the Compensation Committee. The Compensation Committee will have the authority to select those participants to whom awards may be granted, to determine whether and to what extent awards are granted, to determine the number of shares of common stock or other considerations to be covered by each award, to determine the terms and conditions of awards, to interpret and administer the 2025 Plan, and to take any other action consistent with the terms of the 2025 Plan as the Compensation Committee deems appropriate. The Compensation Committee may grant awards subject to vesting schedules or restrictions and contingencies in the Company’s favor, subject to the terms and conditions of the minimum vesting requirement discussed above. The Compensation Committee may (i) delegate to a committee of one or more directors the right to make awards and to cancel or suspend awards and otherwise take action on its behalf under the 2025 Plan (to the extent not inconsistent with applicable law, including the rules of the principal exchange on which our shares are listed), and (ii) to the extent permitted by law, delegate to an executive officer or a committee of executive officers the right to make awards to employees who are not directors or executive officers and the authority to take action on behalf of the Compensation Committee pursuant to the 2025 Plan to cancel or suspend awards under the 2025 Plan to key employees who are not directors or executive officers of the company.

Duration, Amendment and Termination. The 2025 Plan will become effective upon its approval by our shareholders and will expire on the tenth anniversary of such date, except with respect to awards then outstanding, and no further awards may be granted thereafter. In addition to the power to terminate the 2025 Plan at any time, the Board of Directors will also have the power to amend the 2025 Plan; provided, no amendment to the 2025 Plan may be made without shareholder approval if such approval is required by law or agreement, or if such change: increases the number of shares of common stock available for awards under the 2025 Plan, expands the types of awards available under the 2025 Plan, materially expands the class of persons eligible to participate in the 2025 Plan, permits the grant of options or SARs with an exercise or grant price of less than 100% of fair market value on the date of grant, amends the provisions of the 2025 Plan prohibiting the repricing of options and SARs, increases the limits on shares subject to awards, or otherwise

26063747v.1

materially increases the benefits to participants under the 2025 Plan. No amendment may materially impair a participant’s rights under an award previously granted under the 2025 Plan without the written consent of the participant.

Eligibility. Awards may be granted under the 2025 Plan, as determined by the Compensation Committee, to any employee, member of our board of directors, consultant or advisor who is a natural person and provides services to us or a subsidiary, except that incentive stock options which may be granted only to employees.

Limits on Awards to Participants. Subject to adjustment as provided for in the 2025 Plan, no participant may (i) be granted options or SARs during any 12-month period with respect to more than 350,000 shares and (ii) earn more than 350,000 shares for each twelve (12) months in the vesting period or performance period with respect to restricted stock awards, restricted stock unit awards, performance awards and/or other share-based awards. In addition to the foregoing, the maximum dollar value that may be earned by any Participant for each twelve (12) months in a performance period with respect to performance awards that are denominated in cash is $1,000,000. If an award is canceled, the canceled award shall continue to be counted toward the applicable limitation.

Stock Options. The Compensation Committee may grant either non-qualified stock options or incentive stock options. A stock option entitles the recipient to purchase a specified number of shares of our common stock at a fixed price subject to terms and conditions set by the Compensation Committee. The purchase price of shares of common stock covered by a stock option cannot be less than 100% of the fair market value of the common stock on the date the option is granted; provided, however, that in the case of an incentive stock option granted to a participant who, at the time of the grant, owns stock representing more than 10% of the voting power of all classes of stock of the company or any subsidiary, the option price per share shall be no less than 110% of the fair market value of one share on the date of grant. Fair market value of the common stock is generally equal to the closing price for the common stock on our principal exchange on the date the option is granted (or if there was no closing price on that date, on the last preceding date on which a closing price was reported). Options are subject to terms and conditions set by the Compensation Committee.

The 2025 Plan permits payment of the purchase price of stock options to be made by cash or cash equivalents, shares of our common stock previously acquired by the participant, through a net exercise procedure, any other form of consideration approved by the Compensation Committee and permitted by applicable law (including withholding of shares of common stock that would otherwise be issued on exercise), or any combination thereof. Options granted under the 2025 Plan expire no later than 10 years from the date of grant. The proceeds received from the Company from the cash exercise of options or other awards to purchase Common Stock under the 2025 Plan will be used for general corporate purposes.

Stock Appreciation Rights. The Compensation Committee is authorized to grant SARs in conjunction with a stock option or other award granted under the 2025 Plan, and to grant SARs separately. The grant price of a SAR may not be less than 100% of the fair market value of a share of our common stock on the date the SAR is granted. The term of an SAR may be no more than 10 years from the date of grant. SARs are subject to terms and conditions set by the Compensation Committee. Upon exercise of an SAR, the participant will have the right to receive the excess of the fair market value of the shares covered by the SAR on the date of exercise over the grant price. Payment may be made in cash, shares of our common stock or other property, or any combination thereof, as the Compensation Committee may determine. Shares issued upon the exercise of SARs are valued at their fair market value as of the date of exercise.

Restricted Stock Awards. Restricted stock awards may be issued either alone or in addition to other awards granted under the 2025 Plan, and are also available as a form of payment of performance awards and other earned cash-based incentive compensation. The Compensation Committee determines the terms and conditions of restricted stock awards, including the number of shares of common stock granted, and conditions for vesting that must be satisfied, which may be based principally or solely on continued provision of services, and also may include a performance-based component. Unless otherwise provided in the award agreement, the holder of a restricted stock award will have the rights of a shareholder

26063747v.1

from the date of grant of the award, including the right to vote the shares of common stock and the right to receive distributions on the shares (subject to the requirements for dividends on restricted stock awards that vest based on the achievement of performance goals). Except as otherwise provided in the award agreement, any shares or other property (other than cash) distributed with respect to the award will be subject to the same restrictions as the award (subject to the requirements for dividends on restricted stock awards that vest based on the achievement of performance goals).

Restricted Stock Unit Awards. Awards of restricted stock units having a value equal to an identical number of shares of common stock may be granted either alone or in addition to other awards granted under the 2025 Plan, and are also available as a form of payment of performance awards granted under the 2025 Plan and other earned cash-based incentive compensation. The Compensation Committee determines the terms and conditions of restricted stock units, including conditions for vesting that must be satisfied, which may be based principally or solely on continued provision of services, and also may include a performance-based component. The holder of a restricted stock unit award will not have voting rights with respect to the award. Except as otherwise provided in the award agreement, any shares or other property (other than cash) distributed with respect to the award will be subject to the same restrictions as the award (subject to the requirements for dividend equivalents on restricted stock unit awards that vest based on the achievement of performance goals as described under “Dividends; Dividend Equivalents” below).

Other Share-Based Awards. The 2025 Plan also provides for the award of shares of our common stock and other awards that are valued by reference to our common stock or other property (“Other Share-Based Awards”). Such awards may be granted above or in addition to other awards under the 2025 Plan. Other Share-Based Awards may be paid in cash, shares of our common stock or other property, or a combination thereof, as determined by the Compensation Committee. The Compensation Committee determines the terms and conditions of Other Share-Based Awards, including any conditions for vesting that must be satisfied.

Performance Awards. Performance awards provide participants with the opportunity to receive shares of our common stock, cash or other property based on performance and other vesting conditions. Performance awards may be granted from time to time as determined at the discretion of the Compensation Committee. Subject to the share limit and maximum dollar value set forth above under “Limits on Awards to Participants,” the Compensation Committee has the discretion to determine (i) the number of shares of common stock under, or the dollar value of, a performance award and (ii) the conditions that must be satisfied for grant or for vesting, which typically will be based principally or solely on achievement of performance goals.

Performance Criteria. At the Compensation Committee’s discretion, performance goals for restricted stock awards, restricted stock units, performance awards or other share-based awards may be based on the attainment of specified levels of one or more of the following criteria: (a) earnings per share; (b) operating income (before or after taxes); (c) net income (before or after taxes); (d) net sales; (e) cash flow; (f) gross profit; (g) gross profit return on investment; (h) gross margin return on investment; (i) gross margin; (j) working capital; (k) earnings before interest and taxes; (l) earnings before interest, tax, depreciation and amortization (which may also include adjustments to reflect special or other items, or any combination of any or all of the foregoing); (m) return on equity; (n) return on assets; (o) return on capital; (p) return on invested capital; (q) net revenues; (r) gross revenues; (s) new business awards bookings and/or backlog; (t) revenue growth or product revenue growth; (u) total shareholder return; (v) appreciation in and/or maintenance of the company’s market capitalization; (w) cash flow or cash flow per share (before or after dividends); (x) economic value added; (y) the fair market value of the shares of the company’s common stock; (z) the growth in the value of an investment in the company’s common stock assuming the reinvestment of dividends; (aa) reduction in expenses or improvement in or attainment of expense levels or working capital levels; (bb) financing and other capital raising transactions; (cc) debt reductions; (dd) regulatory achievements (including submitting or filing applications or other documents with regulatory authorities, having any such applications or other documents accepted for review by the applicable regulatory authority or receiving approval of any such applications or other documents); or (ee) strategic

26063747v.1

partnerships or transactions (including in-licensing and out-licensing of intellectual property). The performance goals may be based solely by reference to our performance or the performance of one or more of our subsidiaries, divisions, business segments or business units, or based upon the relative performance of other companies or upon comparisons of any of the indicators of performance relative to other companies. The Compensation Committee may also exclude under the terms of the performance awards the impact of an event or occurrence which the Compensation Committee determines should appropriately be excluded, including (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring charges, (ii) an event either not directly related to our operations or not within the reasonable control of our management, or (iii) the cumulative effects of tax or accounting changes in accordance with U.S. generally accepted accounting principles.

Dividends; Dividend Equivalents. Awards other than options and SARs may, if determined by the Compensation Committee, provide that the participant will be entitled to receive, currently or on a deferred basis, cash, stock or other property dividends, or cash payments in amounts equivalent to cash, stock, or other property dividends declared with respect to shares of common stock covered by an award. The Compensation Committee may provide that such amounts will be deemed to have been reinvested in additional shares of common stock or otherwise. Notwithstanding the foregoing, however, dividends, dividend equivalents or other distributions on Awards that are subject to vesting criteria shall not be vested until the Awards have been earned (subject to the same vesting or performance conditions as the underlying Award) and shall be forfeited if the related Award is forfeited.

No Repricing. The 2025 Plan prohibits option and SAR repricings (other than to reflect stock splits, spin-offs or other corporate events described under “Adjustments upon Changes in Capitalization” below, or in connection with a change in control of the company) unless shareholder approval is obtained. For purposes of the 2025 Plan, a “repricing” means a reduction in the exercise price of an option or the grant price of a SAR, the cancellation of an option or SAR in exchange for cash or another award under the 2025 Plan if the exercise price or grant price of the option or SAR is greater than the fair market value of our common stock (except in connection with a change in control, or for awards granted in assumption of or in substitution for awards previously granted by a company acquired by the company or a subsidiary or with which the company or a subsidiary combines), or any other action with respect to an option or SAR that may be treated as a repricing under the rules of the exchange on which our common stock is listed for trading.

Nontransferability of Awards. No award under the 2025 Plan, and no shares subject to awards that have not been issued or as to which any applicable restriction, performance or deferral period has not lapsed, is transferable other than by will or the laws of descent and distribution, and an award may be exercised during the participant’s lifetime only by the participant or the participant’s estate, guardian or legal representative, except that the Compensation Committee may provide in an award agreement that a participant may transfer an award without consideration to certain family members, family trusts, or other family-owned entities, or for charitable donations under such terms and conditions determined by the Compensation Committee.

Forfeiture and Clawback Provisions. The Committee may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, termination of service for cause or any act by a Participant, whether before or after termination of service, that would constitute termination for cause. All Awards granted under the 2025 Plan will be subject to recoupment in accordance with any clawback or recoupment policy that the Company is required to adopt pursuant to the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other applicable law, the Company’s Policy Relating to Recovery of Erroneously Awarded Compensation and any other clawback policy that the Company otherwise adopts, to the extent applicable and permissible under applicable law.

26063747v.1

Adjustments upon Changes in Capitalization. In the event of any merger, reorganization, consolidation, recapitalization, dividend or distribution (whether in cash, shares or other property, other than a regular cash dividend), stock split, reverse stock split, spin-off or similar transaction or other change in our corporate structure affecting our common stock or the value thereof, appropriate adjustments to the 2025 Plan and awards will be made as the Compensation Committee determines to be equitable and appropriate, including adjustments in the number and class of shares of stock available for awards under the 2025 Plan, the number, class and exercise or grant price of shares subject to awards outstanding under the 2025 Plan, and the limits on the number of awards that any person may receive.

Adjustments upon Merger or Change in Control. The 2025 Plan provides that in the event of a merger with or into another corporation or “change in control,” including the sale of all or substantially all of our assets, unless otherwise provided in an award agreement, in the event of a change in control in which the successor company assumes or substitutes for an option, stock appreciation right, restricted stock award, restricted stock unit award or other share-based award, if a participant’s employment or service as a director with such successor company terminates within 24 months following such change in control (or such other period set forth in the award agreement): (i) options and stock appreciation rights outstanding as of the date of such termination of employment will immediately vest, become fully exercisable, and may thereafter be exercised for 24 months (or such other period of time set forth in the award agreement), (ii) the restrictions, limitations and other conditions applicable to restricted stock and restricted stock units outstanding as of the date of such termination of employment shall lapse and such awards shall become free of all restrictions, (iii) the restrictions, limitations and other conditions applicable to performance awards outstanding as of the date of such termination of employment shall lapse and the performance awards shall become free of restrictions, limitations and conditions and become vested in an amount equal to the product of (x) such participant’s target award opportunity with respect to such performance award and (y) the greater of the percentage of performance goals (which performance goals shall be pro-rated or adjusted, if necessary or appropriate, to reflect the portion of the performance period that has been completed) achieved as of the date of the Change in Control and as of the last day of the fiscal quarter ended on or immediately prior to the date of termination; and (iv) the restrictions, limitations and other conditions applicable to any other share-based awards or any other awards shall lapse, and such awards shall become free of all restrictions. However, unless otherwise provided in an award agreement, in the event of a change in control, if the successor company does not assume or substitute for an option, stock appreciation right, restricted stock award, restricted stock unit award or other share-based award, then immediately prior to the change in control: (i) those options and stock appreciation rights outstanding as of the date of the change in control that are not assumed or substituted for shall immediately vest and become fully exercisable, (ii) restrictions, limitations and other conditions applicable to restricted stock and restricted stock units that are not assumed or substituted for shall lapse and the restricted stock and restricted stock units shall become free of all restrictions, (iii) restrictions, limitations and other conditions applicable to performance awards that are not assumed or substituted for (or continued) shall lapse and the performance awards shall become free of restrictions, limitations and conditions and become vested in an amount equal to the product of (A) such Participant’s target award opportunity with respect to such performance award and (B) the percentage of performance goals achieved as of the date of the change in control (which performance goals shall be pro-rated or adjusted, if necessary or appropriate, to reflect the portion of the performance period that has been completed), and (iv) the restrictions, other limitations and other conditions applicable to performance awards outstanding as of the date of such termination of employment shall lapse and the performance awards shall become free of restrictions, limitations and conditions and become vested in an amount equal to the product of (x) such participant’s target award opportunity with respect to such performance award and (y) the greater of the percentage of performance goals (which performance goals shall be pro-rated or adjusted, if necessary or appropriate, to reflect the portion of the performance period that has been completed) achieved as of the date of the Change in Control and as of the last day of the fiscal quarter ended on or immediately prior to the date of termination; and (iv) the restrictions, limitations and other conditions applicable to any other share-based awards or any other awards that are not assumed or substituted for shall lapse, and such other share-based awards or such other awards shall become free of all restrictions.

26063747v.1

Termination of Employment. Subject to the parameters set forth in the 2025 Plan, the Compensation Committee will determine and set forth in the award agreement whether any awards will continue to be exercisable, and the terms of such exercise, on and after the date the participant ceases to be employed by, or to otherwise provide services to, us, whether by reason of death, disability, voluntary or involuntary termination of employment or service, or otherwise.

Federal Income Tax Consequences

The following discussion summarizes certain federal income tax considerations of awards under the 2025 Plan. However, it does not purport to be complete and does not cover federal employment or other tax consequences that may be associated with the 2025 Plan, nor does it describe the state, local or foreign tax considerations or the consequences for any particular individual.

Nonqualified Stock Options. A nonqualified stock option results in no taxable income to the optionee or deduction to the Company at the time of grant. An optionee exercising a non-qualified option will, at that time, realize taxable compensation in the amount of the difference between the then market value of the underlying shares of the Company’s common stock on the exercise date and the option exercise price. Subject to the applicable provisions of the Code, a deduction for federal income tax purposes will be allowable to the Company in the year of exercise in an amount equal to the taxable compensation realized by the optionee. The optionee’s basis in shares relating to non-qualified stock option awards is equal to the sum of the option price plus the amount includible in his or her income as compensation upon exercise. Any gain (or loss) upon subsequent disposition of the shares will be a long-term or short-term gain (or loss), depending upon the holding period of the shares.

Incentive Stock Options. An incentive stock option results in no taxable income to the optionee or deduction for the Company at the time it is granted or exercised (although the excess of the fair market value of the underlying shares on the date of exercise over the exercise price will be included in the optionee’s alternative minimum taxable income for purposes of determining his or her alternative minimum tax). If the optionee holds the stock received as a result of an exercise of an incentive stock option for at least two years from the date of the grant and one year from the date of exercise, then the gain realized on disposition of the stock is treated as a long-term capital gain. If the shares are disposed of prior to the end of this period, however (i.e., a “disqualifying disposition”), then the optionee will include in income, as compensation for the year of the disposition, an amount equal to the excess, if any, of the fair market value of the shares upon exercise of the option over the option price (or, if less, the excess of the amount realized upon disposition over the option price). In that event, the excess, if any, of the sale price over the fair market value on the date of exercise will be a short-term capital gain. In addition, the Company will be entitled to a deduction, in the year of such a disposition, for the amount includible in the optionee’s income as compensation. The optionee’s basis in the shares acquired upon exercise of an incentive stock option is equal to the option price paid, plus any amount includible in his or her income as a result of a disqualifying disposition.

Stock Appreciation Rights. Generally, a participant recognizes no taxable income, and the Company is not entitled to a deduction, when a stock appreciation right or SAR is granted. Upon exercise of a stock appreciation right or SAR, a participant will recognize compensation taxable as ordinary income in an amount equal to the cash and/or the fair market value of the shares received and, subject to the applicable provisions of the Code, the Company will be entitled to a corresponding deduction. A participant’s basis in shares received upon the exercise of an SAR will be equal to the fair market value of such shares on the exercise date, and the participant’s holding period for such shares will begin at that time.

Restricted Stock. Generally, a participant will not recognize taxable income upon the grant of restricted stock. At the time the stock is no longer subject to a substantial risk of forfeiture (as defined in Section 83 of the Code) or, if earlier, becomes transferable, a participant will recognize ordinary income in an amount equal to the fair market value of the

26063747v.1

shares which have become nonforfeitable or transferable and the Company will be entitled to a deduction in the same amount so long as the Company complies with applicable income tax reporting requirements. However, a participant may make an income recognition election under Section 83(b) of the Code, or an 83(b) Election, within 30 days of the grant of restricted stock to recognize taxable ordinary income in the year the stock is awarded in an amount equal to its fair market value at the time of the award, determined without regard to the restrictions. In that event, any gain or loss realized upon the subsequent disposition of shares will be treated as capital gain or loss and the Company will be entitled to a deduction in the same amount so long as the Company complies with applicable income tax reporting requirements.

Restricted Stock Units, Performance Shares and Other Stock-Based Awards. Generally, a participant who receives restricted stock units, performance units or other stock-based awards will not have taxable income under U.S. Federal income tax laws at the time the units or other awards are credited to the participant’s account if the award is subject to a substantial risk of forfeiture during the restricted period. A participant will recognize ordinary income under U.S. Federal income tax laws equal to (i) the amount of cash paid and/or (ii) the fair market value of the shares or other property on the respective payment dates when such cash, shares, and/or other property are delivered or paid in accordance with the terms of the award, which generally will be at the time the substantial risk of forfeiture terminates.. Subject to the applicable provisions of the Code, a deduction for federal income tax purposes will be allowable to the Company in an amount equal to the compensation realized by the participant. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value of the shares on the determination date (as defined above under “Restricted Stock”), will be taxed as capital gain or loss.

The foregoing provides only a general description of the application of federal income tax laws to awards granted under the 2025 Plan. This discussion is intended for the information of shareholders considering how to vote at the annual meeting and not as tax guidance to participants in the 2025 Plan, as the consequences may vary with the types of awards made, the identity of the recipients and the method of payment or settlement.

Registration under the Securities Act of 1933

We plan to register the securities issuable under the 2025 Plan pursuant to a registration statement on Form S-8 as soon as practicable following shareholder approval of this Proposal.

Interests of Certain Persons

Each of our directors and executive officers would be eligible to participate in the 2025 Plan. As a result, approval of the 2025 Plan impacts each of our directors and executive officers and each of them has a personal interest in this proposal and its approval by our shareholders.

New Plan Benefits

No awards have been granted to date under the 2025 Plan. Because awards to be granted in the future under the 2025 Plan are at the discretion of the Compensation Committee, it is not possible to determine the benefits or the amounts to be received under the 2025 Plan by our officers or employees. Pursuant to its non-employee director compensation policy, the Company currently makes an annual grant to its non-employee directors of restricted stock units the 2016 Plan. The Company intends to continue such practice and make such awards under the 2025 Plan, provided the 2025 Plan is approved by the shareholders. For a fuller description of the Company’s non-employee director compensation program, see the discussion above under the caption “Director Compensation-Summary of Non-Executive Director Compensation”. As of the Record Date, approximately 2,800 persons were eligible to receive awards under the 2016 Plan, including (i) our named executive officers, (ii) our non-employee directors and (iii) our worksite employees. During the fiscal year ended September 30, 2024, the following table sets forth awards granted to the persons or groups specified below under our 2016 Plan.

PROPOSAL 5

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

WithumSmith+Brown, PC has served as our independent registered public accounting firm since July 2007. The Audit Committee of our Board of Directors has selected WithumSmith+Brown, PC as our independent registered public accountants for the fiscal year ending September 30, 2025, and has directed that management submit the selection of WithumSmith+Brown, PC as our independent registered public accounting firm for ratification by the shareholders at the annual meeting. Shareholder ratification of the selection of our independent registered public accounting firm is not required by our bylaws, New Jersey corporate law or otherwise. The Board of Directors has elected to seek such ratification as a matter of good corporate practice. Should the shareholders fail to ratify the selection of WithumSmith+Brown, PC as our independent registered public accounting firm, the Audit Committee will reconsider whether to retain that firm for fiscal 2025. Even if the selection is ratified, our 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 our shareholders and the Company. Representatives of WithumSmith+Brown, PC are expected to be present in person at the annual meeting, will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Principal Accountant Fees and Services

The Audit Committee of the Board of Directors of DLH has selected WithumSmith+Brown, PC as its independent registered public accounting firm for the current fiscal year. During fiscal 2024, the audit services that WithumSmith+Brown, PC provided consisted of examination of financial statements, services relative to filings with the SEC, and consultation in regard to various accounting matters. The following table presents the total fees for professional audit and non-audit services rendered by our independent registered public accounting firm for the fiscal years ended September 30, 2024 and 2023, and fees for other services rendered by our independent registered public accounting firm during those periods.


	Year Ended September 30,
	2024		2023
Audit Fees (1)	$	985,240	$	997,950
Audit-Related Fees (2)	$	66,000	$	47,700
Tax Fees (3)	$	—	$	—
All Other Fees (4)	$	—	$	—
Total	$	1,051,240	$	1,045,650

(1) “Audit Fees” consist of fees for professional services rendered for the audit of the Company’s annual financial statements (including, the audit of internal control over financial reporting), review of the interim financial statements included in quarterly reports, and services that are normally provided by the Company’s independent registered public accounting firm in connection with statutory and regulatory filings, including registration statements filed with the Securities and Exchange Commission. The fiscal 2023 audit fees were higher than the fees in fiscal 2024 primarily due to the additional audit procedures for the December 2022 acquisition.

(2) “Audit-Related Fees” consist of fees for services that are traditionally performed by the independent registered public accounting firm, including fees billed or accrued primarily for employee benefit plan audits and other attestation services.

(3) “Tax Fees” consist of fees for professional services rendered for tax compliance, tax advice and tax planning.

26063747v.1

(4) “All Other Fees” consist of fees for those services not captured in the audit, audit-related and tax categories. The Company generally does not request such services from the independent auditors.

Our Audit Committee has determined that the services provided by our independent registered public accounting firm and the fees paid to them for such services has not compromised the independence of our independent registered public accounting firm.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services

Consistent with SEC policies regarding auditor independence, the Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the independent registered public accounting firm. In recognition of this responsibility, the Audit Committee has established a policy to pre-approve all audit and permissible non-audit services provided by the independent registered public accounting firm. Prior to engagement of the independent registered public accounting firm for the next year’s audit, management will submit a detailed description of the audit and permissible non-audit services expected to be rendered during that year for each of four categories of services provided by the independent registered public accounting firm to the Audit Committee for approval. The four categories of services provided by the independent registered public accounting firm are as defined in the footnotes to the fee table set forth above. In addition, management will also provide to the Audit Committee for its approval a fee proposal for the services proposed to be rendered by the independent registered public accounting firm. Prior to the engagement of the independent registered public accounting firm, the Audit Committee will approve both the description of audit and permissible non-audit services proposed to be rendered by the independent registered public accounting firm and the budget for all such services. The fees are budgeted and the Audit Committee requires the independent registered public accounting firm and management to report actual fees versus the budget periodically throughout the year by category of service. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires separate pre-approval before engaging the independent registered public accounting firm. To ensure prompt handling of unexpected matters, the Audit Committee may delegate pre-approval authority to one or more of its members. The member to whom such authority is delegated must report any pre-approval decisions to the Audit Committee at its next scheduled meeting.

Vote Required and Board Recommendation

The affirmative vote of the holders of a majority of the votes cast at the annual meeting is required for the ratification of WithumSmith+Brown, PC as our independent registered public accounting firm for our 2025 fiscal year. The Board of Directors recommends that you vote FOR the ratification of WithumSmith+Brown, PC as our independent registered public accounting firm for our 2025 fiscal year as described in this Proposal 5.

EXECUTIVE COMPENSATION

This section provides information, in tabular and narrative formats specified in applicable SEC rules, regarding the amounts of compensation paid to each of our named executive officers and related information. As a smaller reporting company, we are presenting such information in accordance with the scaled disclosure requirements permitted under applicable SEC regulations.

Executive Summary

The Management Resources and Compensation Committee (the “Compensation Committee”) reviews and establishes the compensation of our executive officers, including the named executive officers, and provides oversight of

26063747v.1

our compensation programs. The Compensation Committee consists entirely of non-employee, independent members of our Board of Directors and operates under a written charter approved by the Board of Directors.

As we are a smaller reporting company under applicable SEC rules, pursuant to Item 402(m) of Regulation S-K we are reporting as our named executive officers, or NEOs, for fiscal 2024, the following individuals whose compensation is set forth below in the Summary Compensation Table and subsequent compensation tables:

•Zachary C. Parker, Chief Executive Officer

•Kathryn M. JohnBull, Chief Financial Officer

•G. Maliek Ferebee, Former Chief Human Resources Officer

In July 2024, DLH disclosed that Mr. Ferebee notified the Company of his decision to resign from his role as our Chief Human Resources Officer effective on August 23, 2024.

Compensation Objectives and Elements of Executive Compensation

The Board, through the Compensation Committee, annually reviews the manner in which it implements our compensation policies in connection with our executives. Our policies will continue to be designed to align the interests of our executives and senior management with the long-term interests of the shareholders. The primary objectives of our executive compensation program are to:

•Provide competitive total compensation opportunities that are consistent with opportunities provided to executives at comparable companies;

•Tie compensation to performance by ensuring that our executives’ total compensation levels vary based on both our short-term financial performance and growth in shareholder value over time;

•Focus and motivate executives on the achievement of defined objectives; and

•Reward executives in accordance with their relative contributions to achieving strategic goals and key corporate objectives.

In designing and administering our executive compensation program, we attempt to strike an appropriate balance among these objectives. Our executive compensation programs consist of three principal elements:

•Base salary compensation;

•Short-term incentive compensation (consisting of cash bonuses); and

•Long-term incentive compensation (consisting of equity-based awards under the 2016 Omnibus Equity Incentive Plan, and generally awarded either in the form of stock options or performance restricted stock units, including a mix of performance-based awards and time-based awards with a multi-year vesting period).

We believe that short-term annual cash incentive compensation should be tied directly to both corporate performance and individual performance for the fiscal year, including the achievement of identified goals as they pertain to the areas of our operations for which the executive officer is personally responsible and accountable and other strategic objectives that will grow long-term shareholder value. Under our program, performance above targeted standards results in increased total compensation, and performance below targeted standards results in decreased total compensation. These components of executive compensation are used together to achieve an appropriate balance between cash and equity compensation and between short-term and long-term incentives. Through the performance criteria embedded in both our short-term incentive programs and long-term awards, a significant portion of each executive officer’s total compensation is at risk, tied both to our annual and long-term performance as well as to the creation of shareholder value.

26063747v.1

Determination of Executive Compensation

The Compensation Committee regularly reviews our executive compensation program and its elements. All decisions by the Compensation Committee relating to the compensation of our executive officers are reported to the full board of directors. In determining the compensation of our executive officers, the Compensation Committee evaluates the elements of the compensation program, including the mix of salary, cash bonus incentive and equity incentives. Within the context of the overall objectives of our compensation program, the Compensation Committee determined the specific amounts of compensation to be paid to each of our executives during fiscal 2024 based on several factors, including the following:

•Financial and operating performance, measured by attainment of specific objectives including revenue growth, EBITDA growth and new business awards;

•Duties, responsibilities and performance of each executive officer, including the achievement of identified goals for the year as they pertain to the areas of our operations for which the executive is personally responsible and accountable;

•Internal pay equity considerations;

•Comparative industry market data to assess compensation competitiveness.

•The individual experience and skills of, and expected contributions from, our executives;

•Our executives’ historical compensation and performance at our company; and

•The contractual commitments we have made to our executives regarding compensation.

In addition, the Compensation Committee considered recommendations made by the Board with respect to our Chief Executive Officer’s compensation, and recommendations from the Chief Executive Officer as well as the Board with respect to determinations of compensation paid to the other executive officers. Our senior management generally applies a similar philosophy and similar policies to determine the compensation of officers and managers who are not executive officers and reports to the Compensation Committee regarding these matters. Further, members of management may provide information to the Compensation Committee that it believes will be helpful to the Compensation Committee in discussing these matters.

Say-on-Pay

The Compensation Committee monitors the results of the annual advisory “say-on-pay” proposal and considers those results as one element in connection with the discharge of its responsibilities. Beginning in 2013, we gave our shareholders an opportunity to provide feedback on our executive compensation program and related proxy disclosure through an advisory vote at our annual shareholders meeting. Shareholders were asked to approve, on an advisory basis, the compensation paid to our named executive officers. A strong majority of our shareholders have indicated approval of the compensation of the named executive officers, with approximately 99% of the votes of the shares present or represented and voting on such matter cast in favor of the proposal at our 2024 annual shareholders meeting. The Compensation Committee will continue to regularly review, assess and, when appropriate, adjust our executive compensation program in response to stockholder feedback. Considering the results of the advisory vote in prior years, the Compensation Committee approached decisions regarding executive compensation policies and decisions for 2024 in a manner consistent with 2023. It is currently expected that we will continue to hold annual say-on-pay votes. Advisory votes on say-on-pay and the frequency of holding the say-on-pay vote are scheduled for this Annual Meeting.

26063747v.1

Role of the Compensation Committee and the Compensation Consultant

During the fiscal year ended September 30, 2023, the Compensation Committee continued its engagement of Korn Ferry as its independent compensation consultant to assist it with compensation decisions concerning our named executive officers and board of directors for the 2024 fiscal year. As part of its engagement, Korn Ferry prepared reports for the Compensation Committee to assist it with its process in determining executive compensation for fiscal 2024, including to implement executive compensation programs that are reasonable, consistent with competitive practices, and appropriately designed to link compensation to our business and strategic objectives. Specifically, Korn Ferry helped to ensure that the Company’s executive compensation practices were competitive, appropriately designed, and aimed at linking executive compensation to the business and strategic objectives of the Company. Korn Ferry provided the Compensation Committee with competitive market data based on a peer group of companies that DLH competes against for products and/or services, recruits human capital from, and/or are similar in size and/or scope to the Company, and used this peer company data to advise the Compensation Committee as to best practices regarding total compensation arrangements for senior executives. The Compensation Committee considered this information in negotiating our new employment agreement with our Chief Financial Officer and in setting compensation levels for our 2024 fiscal year. In addition, during the fiscal year ended September 30, 2024, the Compensation Committee reengaged Korn Ferry to assist it with compensation decisions concerning our named executive officers for the 2025 fiscal year. Additional information on the Compensation Committee’s processes and procedures for the consideration and determination of executive compensation is included under the caption “Corporate Governance - Procedures for Determining Executive and Director Compensation.” In its decision to engage Korn Ferry. the Compensation Committee reviewed their independence in light of SEC and Nasdaq rules and concluded that its work for the Compensation Committee was independent and did not raise any conflict of interest.

Comparative Industry Data

With respect to comparative industry data, the Compensation Committee reviews executive compensation (including the mix of base salary, bonus and equity compensation elements) and evaluates compensation structures of comparable companies, with assistance from the data generated by its compensation consultant in determining the comparatives. That group consists of public companies in the same or similar business lines as DLH as well as competitors for executive talent. For the 2024 fiscal year, the Compensation Committee evaluated the comparative industry data of the peer group that was structured and presented to it by Korn Ferry. The peer group consisted of the following companies:


• American Software, Inc. • Carecloud, Inc. • Computer Programs & Systems, Inc. • CRA International Inc. • Evolent Health, Inc.			• Health Catalyst, Inc • Healthstream, Inc • Information Services Group, Inc. • Mastech Digital, Inc. • NextGen Healthcare, Inc.			• PFSweb Inc. • RCM Technologies Inc. • WidePoint Corp. • Willdan Group, Inc.

In order to identify the peer companies above, Korn Ferry conducted an analysis with consideration of general industry survey data and our need to attract and retain a motivated team of skilled executives. The analysis considered base pay, cash bonus, long-term equity and total compensation data for DLH executives, and compared this information to the competitive market data collected from the group of peer comparators. DLH, however, has not established formal benchmarking targets or objectives for total compensation or the individual elements thereof, and actual compensation may vary significantly from that of the peer group members due to corporate and individual performance.

26063747v.1

Summary Compensation Table

The following table sets forth certain information concerning all cash and non-cash compensation awarded to, earned by or paid to our each of our named executive officers during the fiscal years ended September 30, 2024 and 2023:

(1) “Salary” is comprised of the cash salary paid to the named executive officers during fiscal 2024 and 2023.

(2) “Stock Awards” reflect the portion of grants of restricted stock units awarded to named executive officers under the Company’s 2016 Omnibus Equity Incentive Plan that was recognized by the Company as a compensation expense in the applicable fiscal year in accordance with FASB Accounting Standards Codification Topic 718: Compensation-Stock Compensation, modified to exclude any forfeiture assumptions related to service-based vesting conditions. A discussion of the methods used to calculate these values may be found in the Notes to Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2024. The fair value of the RSUs included in the table include the value of the Time-Based RSUs and Performance RSUs, with the value of the Performance RSUs included in the table assuming vesting at the target level of performance. The amounts in this column do not reflect the value, if any, that ultimately may be realized by the executive.

26063747v.1

Narrative Discussion to Summary Compensation Table

Overview

The Summary Compensation Table above quantifies the amount or value of the different forms of compensation earned by or awarded to our named executive officers in fiscal 2024 and 2023 and provides a dollar amount for total compensation. Descriptions of the material terms of each named executive officer’s employment arrangements with us and related information is provided under “Employment Agreements with named executive officers” below. The agreements provide the general framework and some of the specific terms for the compensation of the named executive officers. Approval of the Compensation Committee and/or the Board of Directors is required prior to our entering into employment agreements with our executive officers or amendments to those agreements. However, many of the decisions relating to compensation for a specific year are made by the Compensation Committee and are implemented without changes to the general terms of employment set forth in those agreements.

Awards of options or shares of restricted stock have been granted under our 2016 Omnibus Equity Incentive Plan (the “2016 Plan”), which is administered by the Compensation Committee. The Compensation Committee has authority to interpret the plan provisions and make all required determinations under those plans. This authority includes making required proportionate adjustments to outstanding awards upon the occurrence of certain corporate events such as reorganizations, mergers and stock splits. Awards granted under the 2016 Plan are generally only transferable to a beneficiary of a participant upon his or her death. However, the committee may establish procedures for the transfer of awards to other persons or entities, provided that such transfers comply with applicable laws.

Base Salary

Our base salary philosophy is to provide reasonable and competitive income to our named executive officers in amounts that will attract and retain individuals with a broad, proven track record of performance. The Compensation Committee approves the salaries for the executive officers. In establishing the salaries, the Compensation Committee balances the need to offer competitive salaries that will limit turnover with the need to maintain careful control of salary and benefit expenses. Individual salaries (except for the salary of the Chief Executive Officer) are recommended by the Chief Executive Officer to the Compensation Committee based on his subjective assessment in each case of the nature of the position, as well as the contribution, performance and experience of the executive officer.

Base salaries for each of our named executive officers are generally determined by the employment agreements that we have entered into with each of them; however, the Compensation Committee retains discretion to adjust annual base salary in a manner consistent with the parameters set forth in such employment agreements. For the year ended September 30, 2024, base salary paid to each of our named executive officers is as set forth in the Summary Compensation Table, above, which amounts are consistent with each officer’s employment arrangement with us. The Compensation Committee may increase base salary payable to each of our named executive officers in its discretion based on its assessment of the Company’s performance.

Consistent with their employment arrangements, the Compensation Committee considered increases in the base salaries payable to our named executive officers for fiscal 2024 based on its review of the performance of each officer and the Company’s overall financial results. Based on its analysis of the level of total cash compensation payable to our named executive officers during fiscal 2023, the Compensation Committee approved for fiscal 2024, increases to the base salary paid to each of our named executive officers for 2024, as set forth in the table below. The base salary for our Chief Executive Officer and our Chief Financial Officer for fiscal 2024 was determined through the negotiations

26063747v.1

between each such officer and the Compensation Committee regarding the terms of their most recent employment agreements. The actual base salary paid to each of our named executive officers for each of fiscal 2024 and fiscal 2023 was as follows:


Executive	2024 Base Salary	2023 Base Salary	% Change
Zachary C. Parker	$725,000	$675,000	7.4%

Kathryn M. JohnBull	$500,000	$430,000	16.3%

G. Maliek Ferebee	$332,325	$315,000	5.5%

In making salary determinations for fiscal 2024, the Compensation Committee evaluated the financial and strategic contributions of the executive officers based on our overall corporate financial performance, business unit financial performance, achievements in implementing our long-term strategy, and with respect to our other named executive officers, the recommendations of the Chief Executive Officer. In addition, the Compensation Committee considered the base salaries for the Company’s named executive officers relative to the base salaries paid by the peer group companies as structured by the compensation consultant and determined that the percentage increase in the approved base salaries for 2024 was appropriate so that the compensation payable to our named executive officers would be in line with a reasonable competitive range. The Compensation Committee believes that the new bases salaries are within a more reasonable competitive range. With respect to the fiscal 2024 base salary for our Chief Financial Officer, the Compensation Committee believed that the increase was also warranted in light of the growth of the Company and corresponding increase in her responsibilities following its recent acquisitions and to ensure that her base salary was sufficiently competitive and that her total direct compensation was close to the median of our compensation peer group. The Compensation Committee gives meaningful weight to the recommendations of the Chief Executive Officer with respect to the compensation of our other named executive officers, but the final decisions regarding executive salaries are made by the Compensation Committee, which also evaluates the analysis of the compensation consultant in considering base salary for the named executive officers. The Chief Executive Officer does not make any recommendations to the Compensation Committee regarding his own compensation.

In addition, based on its analysis of the level of total cash compensation payable to our named executive officers and the performance of the Company and our named executive officers during fiscal 2024, and following its review of the analyses provided by its independent compensation consultant, the Compensation Committee approved increases in the base salary for fiscal 2025 for our named executive officers as shown in the table below. With respect to the Chief Executive Officer, his base salary for 2025 was determined by the Compensation Committee based on its evaluation of his performance during fiscal 2024, as provided for in our employment agreement with him. With respect to the Chief Financial Officer, her base salary for 2025 was determined by the Compensation Committee based on its discussions with the Chief Executive Officer concerning her performance during fiscal 2024 as well as its review of the advice and analyses provided by the compensation consultant.

Short-Term Performance Bonuses

The Compensation Committee may grant bonuses to our named executive officers and other employees to be identified from time to time by the Chief Executive Officer. Bonus awards available to our named executive officers are initially described in our employment agreements with such persons and may provide for the payment of a bonus that is linked to achievement of key performance objectives as approved by the Compensation Committee. The goal of this program is to reward personnel by providing further compensation based on the achievement of goals that the Compensation Committee and the Board of Directors believe correlate closely with the growth of long-term shareholder value. In addition, as an inducement, from time to time we have agreed to guarantee bonus payments in written employment agreements entered into with certain of our named executive officers. Target corporate performance metrics are approved by the Compensation Committee and are linked to the corresponding terms in our employment agreements with our named executive officers and are based on achievement of key objectives (e.g. revenue and EBITDA1 and may include other metrics, such as bookings performance targets) established by the Compensation Committee for each fiscal year. The Compensation Committee may take into consideration the impact of certain non-operating events, including expenses related to strategic initiatives, in determining EBITDA. For our former Chief Human Resources Officer, in addition to performance targets based on quantitative factors applicable to all of our executives, the Compensation Committee also sets performance measures based on factors specific to his areas of responsibility, such as enhancements to our diversity, equity and inclusion efforts, attrition and retention goals, and compliance performance. The Compensation Committee will also assign relative weights to different performance targets determined by it for a given period. The determination of whether the performance criteria shall have been attained shall be solely in the discretion of the Compensation Committee.

As set forth in the table below, under the employment arrangements with our named executive officers effective for fiscal 2024, each officer may receive a performance bonus calculated as a percentage of base salary for each fiscal year of employment. In each case, bonuses will be based on performance targets and other key objectives established by the Compensation Committee. Under our annual incentive program, for our Chief Executive Officer, no bonus for a given performance metric will be awarded if actual results for such metric are less than 85% of the target and no payout will exceed 150% of base salary. The threshold performance level for our other named executive officers is 90% of the target for the applicable metrics and no payout will exceed an amount of 20% above the base salary for such persons. For each 1% variance between the threshold and target, the payout amount will be reduced by 2% of base salary. In addition, for each 1% variance between target and maximum, the payout amount will be increased by 2% of base salary.
