The accompanying proxy statement provides a detailed description of the business to be conducted at the Meeting. We urge you to read the accompanying proxy statement carefully and in its entirety.

This proxy statement is furnished in connection with the solicitation by the Board of Directors (the “Board”) of Climb Global Solutions, Inc., a Delaware corporation (the “Company”), of proxies to be voted at the Annual Meeting of Stockholders (the “Meeting”) to be held on June 3, 2025 at 10:00 a.m., Eastern Daylight Time, and at any postponements or adjournments thereof, for the purposes set forth in the accompanying Notice of Annual Meeting of Stockholders. You will be able to attend the Meeting, vote your shares electronically and submit your questions during the meeting via live audio webcast by visiting www.virtualshareholdermeeting.com/CLMB2025. In order to participate in the Meeting, you must enter the 16-digit voting control number found on your proxy card, voting instruction form or notice that you received previously. If you do not have your control number, you may elect to participate in the Meeting as a “Guest”, but you will not have access to vote your shares or ask questions during the virtual Meeting.

The approximate date on which this proxy statement and the accompanying proxy card is first being made available to the Company’s stockholders is April 29, 2025.

The Board is soliciting your proxy vote for the Meeting because you owned shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), at the close of business on April 7, 2025 (the “Record Date”) for the Meeting, and therefore, are entitled to vote at the Meeting on the following proposals:

The Meeting is scheduled to be held on June 3, 2025, at 10:00 a.m., Eastern Daylight Time. The Meeting will be held exclusively online via live webcast. We are continuing with a virtual format for our Meeting by leveraging the latest technology to provide expanded access, while remaining committed to ensuring that our stockholders will be afforded the same rights and opportunities participating in the virtual meeting as they would at an in-person meeting. The virtual format allows stockholders to participate in more public company annual meetings from any location around the world, at no cost to them. While you will not be able to attend the Meeting at a physical location, as a stockholder of the Company, you will be able to attend the Meeting online, vote your shares electronically and submit questions during the Meeting via live audio webcast by visiting www.virtualshareholdermeeting.com/CLMB2025. You must enter the 16-digit voting control number found on your proxy card, voting instruction form or notice that you received previously. If you do not have your control number, you may elect to participate in the Meeting as a “Guest”, but you will not have access to vote your shares or ask questions during the virtual Meeting.

The Board, on behalf of the Company, is soliciting your proxy to vote your shares of Common Stock on all matters scheduled to come before the Meeting, and at any adjournment or postponement of the Meeting, whether or not you attend the Meeting. By completing, signing, dating, and returning the proxy card or voting instruction form, or by submitting your proxy and voting instructions over the Internet or by telephone, you are authorizing the persons named as proxies to vote your shares of Common Stock at the Meeting as you have instructed.

You may also be solicited by press releases issued by us, postings on our corporate website or other websites or otherwise. Unless expressly indicated otherwise, information contained on our corporate website is not part of this proxy statement. In addition, none of the information on the other websites, if any, listed in this proxy statement is part of this proxy statement. Such website addresses are intended to be inactive textual references only.

Our Board recommends that you vote by proxy with respect to the proposals as follows:

The Board has set the close of business on April 7, 2025 as the Record Date for the Meeting. You are entitled to notice and to vote if you were a stockholder of record of Common Stock, as of the close of business on the Record Date. You are entitled to one vote on each proposal for each share of Common Stock you held as of the Record Date. Your shares of Common Stock may be voted at the Meeting only if you are present in person or your shares are represented by a valid proxy. At the close of business on the Record Date, there were 4,584,055 shares of our Common Stock issued, outstanding and entitled to vote at the Meeting.

If your shares of Common Stock are registered directly in your name, you are considered the stockholder of record with respect to such shares. The Company sent the proxy materials directly to you. The proxy card accompanying this proxy statement will provide information regarding internet and telephone voting for record holders.

If your shares of Common Stock are held in a stock brokerage account or by a bank, trust or other nominee, then the broker, bank, trust or other nominee is considered to be the stockholder of record with respect to such shares. You are considered to be the beneficial owner of such shares and such shares are said to be held in “street name,” and the proxy materials are being forwarded to you by that organization. Street name holders generally cannot submit a proxy or vote their shares directly and must instead instruct the broker, bank, trust or other nominee how to vote their shares. If you hold your shares in “street name,” please instruct your bank, broker, trust or other nominee how to vote your shares using the voting instruction form provided by your bank, broker, trust or other nominee so that your vote can be counted. The voting instruction form provided by your bank, broker or other nominee may also include information about how to submit your voting instructions over the Internet or by telephone, if such options are available.

Our Bylaws provide that the presence in person or by proxy of holders of a majority of the voting power of the outstanding capital stock of the Company entitled to vote at the Meeting constitutes a quorum, which is required to hold and conduct business at the Meeting. Shares are counted as present at the Meeting if:

If you are a record holder and you submit your proxy, regardless of whether you abstain from voting on one or more matters, your shares will be counted as present at the Meeting for the purpose of determining a quorum. If your shares are held in “street name,” your shares are counted as present for purposes of determining a quorum if you provide voting instructions to your broker, bank, trust or other nominee and such broker, bank, trust or other nominee submits a proxy covering your shares. Broker non-votes (as described below) also count as present for purposes of determining a quorum. In the absence of a quorum or for any other reason, the Meeting may be adjourned, from time to time, by the chairman of the meeting or the Chair of our Board (“Board Chair”). Additionally, in the absence of a quorum or for any other reason, the Meeting may be adjourned, from time to time, by a majority vote of the stockholders present in person or represented by proxy and entitled to vote. If the adjournment is not for more than thirty days, the adjourned Meeting may be held without any notice other than an announcement at the Meeting.

You will be able to attend the Meeting and vote and submit questions during the Meeting via live audio webcast by visiting www.virtualshareholdermeeting.com/CLMB2025. In order to be considered present at the Meeting and vote your shares, you must enter the 16-digit voting control number found on your proxy card, voting instruction form or notice that you received previously. If you do not have your control number, you may elect to participate in the Meeting as a “Guest”, but you will not have access to vote your shares or ask questions during the virtual Meeting.

Online access to the audio webcast will open approximately 15 minutes prior to the start of the Meeting to allow time for you to log in and test the computer audio system. We encourage our stockholders to access the Meeting prior to the start time. If you encounter any difficulties accessing or hearing the Meeting during the check-in or meeting time, please call the technical support number that will be posted on the Meeting log-in page.

As part of the Meeting, we will hold a live Q&A session, during which we intend to answer appropriate questions submitted by stockholders during the Meeting that are pertinent to the Company and the Meeting matters.

Stockholders may submit questions during the Meeting using the “Ask a Question” field on the virtual Meeting website. You will need to log in to www.virtualshareholdermeeting.com/CLMB2025 with your 16-digit control number found on your proxy card, voting instruction form or notice that you received previously to submit a question.

Only stockholders that have accessed the Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “How do I attend and vote at the Meeting?” will be permitted to submit questions during the Meeting. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things:

The process for voting your shares depends on how your Common Stock is held. Generally, you may hold Common Stock in your name as a “stockholder of record” or in an account with a broker, bank, trust or other nominee (i.e., in “street name”). If your shares are registered in your name, you may vote your shares in person at the Meeting or by proxy whether or not you attend the Meeting.

You may also vote using any of the following methods:

Even if you plan to attend the Meeting, we recommend that you also submit your proxy or voting instructions by Internet, telephone or mail so that your vote will be counted if you later decide not to attend the Meeting. The Internet and telephone voting facilities will close at 11:59 p.m. Eastern Daylight Time on June 2, 2025. Stockholders who submit a proxy by Internet or telephone need not return a proxy card or the form forwarded by your broker, bank, trust or other holder of record by mail.

As a stockholder of record, if you submit a proxy, you may revoke that proxy at any time before your shares are voted at the Meeting. Stockholders of record may revoke a proxy prior to the Meeting by (i) delivering a written notice of revocation that is dated later than the date of your proxy to the attention of the Corporate Secretary at our offices at 4 Industrial Way West, 3rd Floor, Eatontown, New Jersey 07724, (ii) signing and delivering a later-dated proxy over the Internet, by telephone or by mail, that we receive no later than 11:59 p.m. Eastern Daylight Time on June 2, 2025 or (iii) attending and voting at the Meeting. Attendance at the Meeting will not, by itself, revoke a proxy.

If your shares are held in the name of a broker, bank, trust, or other nominee, you may change your voting instructions by following the instructions of your broker, bank, trust, or other nominee.

Stockholders of record as of the close of business on the Record Date, are entitled to one vote for each share of Common Stock held on each matter to be voted upon at the Meeting. All shares entitled to vote and represented by properly submitted proxies received before the polls are closed at the Meeting, and not revoked or superseded, will be voted at the Meeting in accordance with the instructions indicated on those proxies. If you return a validly executed proxy card without indicating how your shares should be voted on a matter and you do not revoke your proxy, your proxy will be voted: “FOR” the election of the five Board nominees (Proposal 1); “FOR” the non-binding, advisory resolution approving the compensation of the Company’s named executive officers (Proposal 2); “FOR” the option of once every year for the frequency of future advisory votes on executive compensation (Proposal 3); and “FOR” the ratification of the appointment of Deloitte as our independent registered public accounting firm for the fiscal year ending December 31, 2025 (Proposal 4). Validly executed proxy cards will be voted in the discretion of the proxy holders with respect to any other matters that may properly come before the Meeting.

A broker non-vote occurs when the broker is unable to vote on a proposal because the proposal is not routine and the stockholder who owns the shares in “street name” has not provided any voting instructions to the broker on that matter. The New York Stock Exchange (“NYSE”) rules determine whether proposals are routine or not routine. If a proposal is routine, a broker holding shares for an owner in street name may vote on the proposal without voting instructions. Proposal 1, Proposal 2 and Proposal 3 are considered non-discretionary matters, and a broker lacks the authority to vote uninstructed shares at their discretion on such proposals. Proposal 4 is considered a discretionary matter, and a broker will be permitted to exercise its discretion to vote uninstructed shares on the proposal. If your shares are held in street name, please follow the voting instructions that you receive from that institution. The institution will not be able to vote your shares on any of the proposals except the ratification of the appointment of Deloitte unless you have provided voting instructions. Broker non-votes are not treated as entitled to vote for all other matters proposed for a vote at the meeting, so they will have no effect on those matters.

Abstentions and broker non-votes will be counted as present at the Meeting for the purpose of determining a quorum. Because the election of each director nominee will require a plurality of the shares of Common Stock present in person or represented by proxy entitled to vote at the Meeting, “withhold” votes have no effect on the outcome of Proposal 1. Abstentions may not be specified with respect to Proposal 1. To approve the advisory vote on the compensation of the Company’s named executive officers, the frequency of future advisory votes on executive compensation and to ratify the appointment of Deloitte as the Company’s independent registered public accounting firm for the fiscal year ending 2025, if a quorum is present, the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy at the Meeting and entitled to vote is required for approval. As a result, abstention votes will have the same effect as a vote against such matters. Broker non-votes are not treated as entitled to vote on Proposals 1, 2 and 3, so they will have no effect on those matters. Proposal 4 is considered a discretionary matter, and we do not expect there will be broker non-votes on this proposal.

We do not expect any other items of business will be presented for consideration at the Meeting other than those described in this proxy statement. However, by completing, signing, dating, and returning the proxy card or submitting your proxy or voting instructions over the Internet or by telephone, you will give to the persons named as proxies discretionary voting authority with respect to any matter that may properly come before the Meeting.

All votes will be tabulated as required by Delaware law, the state of our incorporation, by the inspector of election appointed for the Meeting in accordance with our Bylaws, who will separately tabulate affirmative and negative votes, abstentions, and broker non-votes.

The final voting results will be reported in a Current Report on Form 8-K, which will be filed with the Securities and Exchange Commission (the “SEC”) within four business days after the Meeting. If our final voting results are not available within four business days after the Meeting, we will file a Current Report on Form 8-K reporting the preliminary voting results and subsequently file the final voting results in an amendment to the Current Report on Form 8-K within four business days after the final voting results are known to us.

Election of Directors. Pursuant to our Bylaws, the affirmative vote of a plurality of the shares of Common Stock present in person or represented by proxy and entitled to vote at the Meeting is necessary for the election of directors under Proposal 1 at the Meeting. This means that the nominees receiving the highest number of “FOR” votes of the shares entitled to be voted in the election of directors will be elected. You may vote “FOR ALL” all Board nominees, “WITHHOLD ALL” your vote as to all Board nominees, or “FOR ALL EXCEPT” one or more specific nominees from whom you “WITHHOLD” your vote. There is no “against” option. Shares voting “WITHHOLD” are counted for purposes of determining a quorum. However, if you withhold authority to vote with respect to the election of any or all of the nominees, your shares will not be voted with respect to those nominees indicated and your shares will

have the same effect as an abstention and will not count as a vote “FOR” or “AGAINST” a director, because directors are elected by plurality voting. Therefore, “WITHHOLD” votes will not affect the outcome of Proposal 1. Brokers do not have discretionary authority to vote on the election of directors. Broker non-votes will have no effect on the outcome of Proposal 1. Shares may not be voted for more than the number of director nominees listed on the submitted proxy card and stockholders may not cumulate votes.

Non-binding Resolution to Approve Compensation for Named Executive Officers. The approval of a non-binding, advisory resolution approving the compensation of the Company’s named executive officers requires the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy at the Meeting and entitled to vote. You may vote “FOR,” “AGAINST” or “ABSTAIN.” If you “ABSTAIN” from voting on Proposal 2, the abstention will have the same effect as an “AGAINST” vote. Broker non-votes will have no effect on the outcome of Proposal 2. While the vote on Proposal 2 is advisory and will not be binding on the Company or the Board, the Board will review the results of the voting on this proposal and take it into consideration when making future decisions regarding executive compensation as we have done in this and previous years.

Ratification of Auditors. The ratification of the appointment of Deloitte requires the affirmative vote of a majority of the shares of Common Stock present in person or represented by proxy at the Meeting and entitled to vote. You may vote “FOR,” “AGAINST” or “ABSTAIN.” If you “ABSTAIN” from voting on Proposal 4, the abstention will have the same effect as an “AGAINST” vote. Proposal 4 is considered a discretionary matter, and a broker will be permitted to exercise its discretion to vote uninstructed shares on the proposal.

The Company will bear the entire cost of solicitation of proxies, including preparation, assembly and mailing of this proxy statement, the proxy card, the Notice of Annual Meeting of Stockholders, and any additional information furnished to stockholders. Copies of solicitation materials will be furnished to banks, brokerage houses, fiduciaries and custodians holding shares of our Common Stock in their names that are beneficially owned by others to forward to those beneficial owners. We may reimburse persons representing beneficial owners for their costs of forwarding the solicitation materials to the beneficial owners. Proxies may be solicited by telephone, facsimile, electronic mail or personal solicitation. Our directors, officers, and employees may also solicit proxies for no additional compensation.

None of the applicable Delaware law, our Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), nor our Bylaws, provide for appraisal or other similar rights for dissenting stockholders in connection with any of the proposals set forth in this proxy statement. Accordingly, you will have no right to dissent and obtain payment for your shares in connection with such proposals.

In accordance with the General Corporation Law of the State of Delaware and our Certificate of Incorporation and Bylaws, our business, property and affairs are managed under the direction of the Board. Although our non-employee directors are not involved in our day-to-day operating details, they are kept informed of our business through written reports and documents provided to them regularly, as well as by operating, financial and other reports presented by our officers at meetings of the Board and committees of the Board.

Our Board believes that the purpose of corporate governance is to ensure that we maximize stockholder value in a manner consistent with legal requirements and the highest standards of integrity consistent with our fiduciary responsibilities. The following section provides an overview of the Company’s corporate governance structure, including key governance documents that guide the Board and management in the performance of their duties.

The Board and management regularly review best practices in corporate governance and are committed to a structure that fosters principled actions, informed and effective decision-making, and appropriate monitoring of compliance and performance. The Company’s current practices are highlighted below:

The Company places significant importance on corporate governance and business ethics. The Board is composed of independent directors, other than the CEO, with diverse backgrounds who bring a wealth of knowledge and business experience to the Company.

The Company is committed to fostering an effective risk management environment to serve the interests of the Company, its customers, and its stockholders. The Board has adopted the Code of Business Conduct Ethics & Anti-Corruption Policies to make clear its expectation for the conduct of our directors, officers and employees.

The Board believes it is appropriate to separate the roles of Chief Executive Officer (“CEO”) and Board Chair as a result of the demands of and differences between each role. John McCarthy serves as the Board Chair. Dale Foster serves as our CEO and as a member of our Board. Our Board believes that this leadership structure provides the most efficient and effective leadership model for our Company by enhancing the ability of the Board Chair and CEO to provide clear insight and direction of business strategies and plans to both the Board and management. Separating the CEO and Board Chair roles allows us to efficiently develop and implement corporate strategy that is consistent with the Board’s governance and oversight role, while facilitating strong day-to-day executive leadership.

The duties and responsibilities of our Board Chair include: (i) chairing Board meetings, including presiding over all executive sessions of the Board (without management present) at regularly scheduled Board meetings; (ii) consulting with the CEO on such other matters as are pertinent to the Board and the Company; (iii) working with management to determine the information and materials provided to Board members; (iv) creating Board meeting schedules, agenda and other information provided to the Board; (v) the authority to call meetings of the independent directors; (vi) serving as principal liaison between the independent directors and the CEO and between the independent directors and senior management; and (vii) being available for direct communication and consultation with stockholders upon request. Our CEO is responsible for setting the strategic direction for the Company, with guidance from the Board. The CEO is also responsible for the day-to-day leadership and performance of the Company, while the Board Chair provides guidance to the CEO, sets the agenda for Board meetings and presides over meetings of the full Board.

Another key component of our leadership structure is our strong governance practices designed to ensure that the Board effectively carries out its responsibility for the oversight of management. All of our directors, except Mr. Foster, are independent, and all Board committees are comprised entirely of independent directors. Our independent directors meet at each Board meeting in regularly scheduled executive sessions (not less than twice per year) and may schedule additional executive sessions as appropriate. Members of management do not attend these executive sessions. The Board has full access to the management team at all times. In addition, the Board or any committee thereof may retain, on such terms as determined by the Board or such committee, as applicable, in its sole discretion, independent legal, financial and other consultants and advisors to assist the Board or committee, as applicable, in discharging its oversight responsibilities.

Our Board believes that overseeing how management manages the various risks we face is one of its most important responsibilities to the Company’s stakeholders. The Board believes that, in light of the interrelated nature of the Company’s risks, oversight of risk management is the responsibility of the full Board. In carrying out this critical duty, the Board meets regularly with key members of management holding primary responsibility for management of risk in their respective areas.

In March 2025, our Board disbanded the Risk and Security Committee and reallocated its responsibilities to the Audit Committee. This reallocation of responsibilities consolidates the Company’s risk oversight functions within a single Board committee, providing for a more integrated and comprehensive approach to risk management. In connection with this transition, the Audit Committee’s charter was amended and restated to reflect its expanded role in risk oversight. The Audit Committee now oversees the Company’s enterprise risk management framework, including risks relating to financial reporting, operational performance, regulatory compliance, cybersecurity, data privacy, and other emerging risks. As part of this oversight, the Audit Committee periodically reviews and discusses with management the Company’s major risk exposures and the policies and procedures in place to monitor and mitigate such risks. The Audit Committee also reviews internal controls related to information technology and cybersecurity and receives reports on the Company’s incident response plans, including any significant cybersecurity events or data breaches and the associated remediation efforts.

The Board met ten times in 2024. Each of the directors attended at least 75% of the aggregate of all meetings held by the Board and meetings of each committee of the Board on which such director served during 2024.

Stockholders may communicate with a member or members of the Board by addressing their correspondence to the Board member or members c/o the Corporate Secretary, Climb Global Solutions, Inc., 4 Industrial Way West, 3rd Floor, Eatontown, New Jersey 07724. Our Corporate Secretary will review the correspondence and forward it to the chair of the appropriate committee or to any individual director or directors to whom the communication is directed, unless the communication is unduly hostile, threatening, or illegal, does not reasonably relate to the Company or our business, or is similarly inappropriate. Our Corporate Secretary has the authority to discard or disregard any inappropriate communications or to take other appropriate actions with respect to any such inappropriate communications.

Recognizing that director attendance at our annual meetings can provide our stockholders with a valuable opportunity to communicate with Board members about issues affecting our Company, we encourage our directors to attend each annual meeting of stockholders. All of the directors then serving on the Board attended last year’s annual meeting of stockholders.

The Board has determined that the following directors are independent under the NASDAQ listing standards: Messrs. Bryant, McCarthy and Giovacchini and Ms.  Gold.

The Board has three standing committees: an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee (each, a “Committee” and collectively, the “Committees”). The Board previously had a Risk and Security Committee until it was disbanded in March 2025, with the oversight responsibilities assumed by the Audit Committee.

Audit Committee. The Board has an Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Audit Committee: (i) monitors the integrity of the Company’s financial statements, financial reporting process and internal controls regarding finance, accounting and legal compliance; monitors the independence and performance of our independent registered public accounting firm; (ii) provides an avenue of communication among the independent registered public accounting firm, management, and our outsourced internal auditors, and our Board; and (iii) oversees the Company’s enterprise risk management framework, including risks relating to financial reporting, operational performance, regulatory compliance, cybersecurity, data privacy, and other emerging risks. The current members of the Audit Committee are Messrs. Bryant (Chair) and McCarthy and Kimberly Boren, each of whom is independent as defined by the NASDAQ listing standards and applicable SEC rules. Ms. Boren is not standing for re-election, and her term will end at the Meeting. The Board intends to appoint Mr. Giovacchini to fill the vacancy on the Audit Committee, effective as of the Meeting. The Board has determined that Mr. Bryant meets the criteria as an “audit committee financial expert” as defined in applicable SEC rules. The Audit Committee met four times during 2024.

The Audit Committee operates under a written charter adopted by the Board. A copy of the charter is available on our website at https://www.climbglobalsolutions.com/investors/ in the Governance Documents section under the Governance tab.

Compensation Committee. The Compensation Committee charter provides that the Compensation Committee shall be comprised of no fewer than two members. Further, the Compensation Committee charter details the principal functions of the Compensation Committee, including: (i) reviewing and approving the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and based on such evaluation recommending the compensation of our Chief Executive Officer to the independent members of the Board for consideration; (ii) recommending the compensation of the other executive officers to the Board for consideration; (iii) reviewing and recommending to the Board (or, with respect to the CEO, the independent members of the Board) for approval the following as they affect the executive officers: employment and severance arrangements and change in control provisions affecting any elements of compensation and benefits; (iv) making recommendations to the Board with respect to cash incentive compensation plans and equity-based plans and to perform such duties and responsibilities as may be assigned to the Committee under the terms of such plans; and (v) assisting management in complying with our proxy statement and annual report disclosure requirements. Under its charter, the Compensation Committee may retain independent consultants and advisors (such independence to be determined pursuant to Nasdaq Listing Rules) to advise the committee on compensation issues requiring outside expertise. The current members of the Compensation Committee are Ms. Gold (Chair) and Mr. McCarthy, each of whom is independent as defined by the NASDAQ listing standards. The Compensation Committee met one time during 2024.

The Compensation Committee operates under a written charter adopted by the Board, a copy of which is available on our website at https://www.climbglobalsolutions.com/investors/ in the Governance Documents section under the Governance tab.

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee charter provides that the Nominating and Corporate Governance Committee shall be comprised of no fewer than three members. The Nominating and Corporate Governance Committee identifies individuals qualified to become Board members and recommends to the Board director nominees for election at the next Annual Meeting of Stockholders or to fill vacancies on the Board. The Nominating and Corporate Governance Committee also oversees the Company’s corporate governance practices and procedures, and ensures the Board has a formal succession plan for executive management. Currently, the members of the Nominating and Corporate Governance Committee are Ms. Boren (Chair) and Messrs. Bryant and Scorziello each of whom is independent as defined by the NASDAQ listing standards. Ms. Boren and Mr. Scorziello are not standing for re-election and their term will end at the Meeting. The Board intends to appoint Ms. Gold to fill the vacancies on the Nominating and Corporate Governance Committee, effective as of the Meeting. The Nominating and Corporate Governance Committee met two times during 2024.

The Nominating and Corporate Governance Committee operates under a written charter adopted by the Board. The Nominating and Corporate Governance Committee charter is available in the Governance Documents section under the Governance tab of our website at https://www.climbglobalsolutions.com/investors.

Nominees may be recommended by directors, members of management, or, in some cases, by a third-party firm. In identifying and considering candidates for nomination to the Board, the Nominating and Corporate Governance Committee considers, in addition to the requirements described below and set out in its charter, quality of experience, our needs and the range of knowledge, experience and diversity represented on the Board. Each director candidate will be evaluated by the Nominating and Corporate Governance Committee based on the same criteria and in the same manner, regardless of whether the candidate was recommended by a Company stockholder or by others. The Nominating and Corporate Governance Committee will conduct the appropriate and necessary inquiries with respect to the backgrounds and qualifications of all director nominees. The Nominating and Corporate Governance Committee will also review the independence of each candidate and other qualifications of all director candidates, as well as consider questions of possible conflicts of interest between director nominees and our Company.

After the Nominating and Corporate Governance Committee has completed its review of a nominee’s qualifications and conducted the appropriate inquiries, the Nominating and Corporate Governance Committee will make a determination whether to recommend the nominee for approval by the Board. If the Nominating and Corporate Governance Committee decides to recommend the director nominee for approval by the Board and such recommendation is accepted by the Board, our proxy solicitation will include the director nominee.

In addition to the candidates nominated by the Board pursuant to the recommendations of the Nominating and Corporate Governance Committee in the manner set forth above, the Nominating and Corporate Governance Committee will consider recommendations for nominations submitted by our stockholders. Stockholders who wish the Nominating and Corporate Governance Committee to consider their recommendations for nominees for the position of director should submit their recommendations in writing to: Corporate Secretary, Climb Global Solutions, Inc., 4 Industrial Way West, 3rd Floor, Eatontown, New Jersey 07724.

In its assessment of each potential candidate, the Nominating and Corporate Governance Committee will review the nominee’s professional ethics, integrity and values, skills, judgment, experience, independence, commitment to representing the long-term interests of the stockholders, understanding of our Company’s or other related industries and such other factors as the Nominating and Corporate Governance Committee determines are pertinent in light of the current needs of the Board. The Nominating and Corporate Governance Committee seeks to identify candidates representing diverse thought and experience at policy-making levels in business, management, marketing, finance, human resources, communications, risk and compliance and in other areas that are relevant to our activities. The Nominating and Corporate Governance Committee will also take into account the ability of a director to devote the time and effort necessary to fulfill his or her responsibilities to our Company. After full consideration, the stockholder proponent will be notified of the decision of the Nominating and Corporate Governance Committee.

The following table sets forth information regarding the compensation earned by or awarded to each director, who is not a named executive officer who served on the Board, for the fiscal year ended December 31, 2024.

The Company qualifies under SEC rules as a smaller reporting company (“SRC”). As such, the Company has elected to provide for the scaled disclosure permitted by Rule 402(m) of Regulation S-K. The Company has included this Compensation Overview to provide disclosure of changes made to its compensation practices in recent years. This Compensation Overview identifies the elements of compensation and explains the compensation objectives and practices for the Company’s named executive officers. The Company’s named executive officers for the fiscal year ended December 31, 2024 are:

On January 9, 2025, the Board and Andrew Clark, the Company’s then Chief Financial Officer, mutually agreed that Mr. Clark will resign from his positions as Chief Financial Officer and Vice President of the Company, effective as of January 10, 2025.

The Compensation Committee is charged with the responsibility for establishing, implementing, and monitoring adherence to the Company’s compensation philosophy and ensuring that executives and key management personnel are appropriately compensated and making recommendations to the Board regarding the compensation of the Company’s executive officers. The Compensation Committee generally meets annually to re-evaluate the appropriate level of base compensation and incentive compensation for our executive officers.

Compensation Philosophy and Objectives. The Compensation Committee seeks to structure each element of compensation to attract and retain the necessary executive talent, reward annual performance and provide incentives for both long-term strategic goal planning and achievement as well as short-term performance. The Compensation Committee’s policy for allocating between currently paid and long-term compensation is to ensure adequate base compensation to attract and retain personnel, while providing incentives to maximize long-term value for our stockholders.

Elements of Compensation. The total compensation program for the Company’s executive officers consists of the following:

Say On Pay Considerations and Say on Frequency Results. The Compensation Committee will continue to consider emerging compensation practices and stockholder feedback, including Say-on-Pay voting results, as part of its decision-making process. At the 2024 Annual Meeting of Stockholders, the Company’s stockholders voted to approve the Company’s named executive officer compensation with a favorable vote of 88% of the votes cast. At the 2023 Annual Meeting of Stockholders, the Company’s stockholders voted to approve the Company’s named executive officer compensation with a favorable vote of 91% of the votes cast.

Additionally, at the 2019 Annual Meeting of Stockholders, our stockholders approved, on a non-binding advisory basis, every year as the frequency of future advisory votes on our named executive officer compensation, with over 90% of the votes cast in favor of annual advisory votes.

Total cash compensation for 2024 is divided into a base salary portion and a bonus. Many factors are considered in determining the base salaries for executive officers, including the value that each individual brings to the Company through experience, education and training, comparable positions and comparable responsibilities at similar organizations, the specific needs of the Company, and the individual’s past and expected future contributions to the Company’s success. Compensation for our executives includes both fixed and performance-based components, with an emphasis on performance-based elements to support the objectives listed below. The Company considers a component to be performance-based if the amount eventually earned or paid varies based on one or more elements of the Company’s financial performance (e.g., profit margins, operating income, etc.). Performance-based components are designed so that above-plan performance is rewarded with above-target payouts and vice versa.

After reviewing the base salaries of executive officers and upon recommendation by the Compensation Committee, in 2024, the Board approved adjustment to Mr. Foster’s annualized base salary to better align his compensation with his role, responsibilities and expected operational activities, while the annualized base salary of the other named executive officers included in the table below remained the same.

In February 2024, the Compensation Committee recommended, and the Board approved, performance cash bonus awards for 2024 (the “Performance Bonus Awards”) which were developed based on the performance metrics below.

Pursuant to the Performance Bonus Awards, the Company’s executive officers were eligible to receive cash incentive payments for 2024 dependent on the Company’s performance achievement against the specific metric listed below. The Compensation Committee established performance goals for the Company’s 2024 fiscal year in February 2024. Because payments of cash awards under the Performance Bonus Awards are determined by comparing actual performance to the performance goals established by the Compensation Committee, it is not possible to predict at the time of grant the actual amount of future benefits that will be paid under the Performance Bonus Awards.

The target in the Performance Bonus Awards was earnings before interest, taxes, depreciation and amortization (“EBITDA”) (which is a non-GAAP measure as reconciled in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, in the Company’s Annual Report on Form 10-K on pages 23 and 24). Specific targets were determined by the Compensation Committee based on a review of the Company’s 2024 budget prepared by management and the factors described above. The targets are set at levels that, upon achievement of 100% of the target performance, are likely to result in bonus payments that the Compensation Committee believes reflect the Company’s strategic plan designed to increase stockholder value. The following table shows, for fiscal year 2024, the potential range of bonus payouts and the actual bonus payouts achieved as a percentage of the target, for each of the named executive officers.

The Company’s executive officers are eligible to receive equity incentive awards under the 2021 Plan. The primary goal of the Company is to create long-term value for stockholders, and accordingly the Compensation

Committee believes that equity incentive awards provide an additional incentive to executive officers to work towards maximizing stockholder value. The Compensation Committee views equity incentive awards as one of the more important components of the Company’s long-term, performance-based compensation philosophy. The grant of equity incentive awards to executive officers encourages equity ownership in the Company, and closely aligns executive officers’ interests to the interests of the stockholders.

Equity incentive awards may be provided through initial grants at or near the date of hire, and through annual time-vested and performance-based grants. Equity incentive awards vest at such times and based such vesting conditions as are recommended by the Compensation Committee and approved by the Board and are settled promptly upon vesting. The initial grant is designed for the level of skills required to fulfill the executive’s responsibilities and is designed to motivate the officer to make the kind of decisions and implement strategies and programs that will contribute to an increase in the Company’s enterprise value over time. Periodic additional equity incentive awards within the comparable range for the job are granted to reflect the executive’s ongoing contributions to the Company, to create an incentive to remain at the Company and to provide a long-term incentive to achieve or exceed the Company’s financial goals. In February 2024 the Compensation Committee recommended, and the Board approved, time-vested and performance-vested restricted stock units (“RSUs”). The time-vested RSUs vest in three equal annual installments and represent 40% of the total target annual award. Performance based RSUs vest based on continued service through January 1 following the last day of the performance cycle and attainment of an earnings per share (“EPS”) target and a return on equity target (“ROE”) and represent 60% of the award. The performance-based RSUs are based 70% on the EPS goal and 30% on the ROE goal and can be earned from 0-150% of the target award amount.

Severance and Change-in-Control Arrangements. As stated above, the Compensation Committee believes that the interests of stockholders are best served by ensuring that the interests of our senior management are aligned with those of our stockholders. We believe that companies should provide reasonable severance benefits to executive officers due to the greater level of difficulty they face in finding comparable employment in a short period of time. In addition, in the change in control context, we believe that executive officers face a greater risk of job loss or modification as a result of a change-in-control transaction than other employees. By reducing the risk of job loss or reduction in authority, the severance and change-in-control provision we maintain under our Severance Plan helps ensure that our executive officers support potential change-in-control transactions that may be in the best interests of our stockholders, even though the transaction may create uncertainty in their personal employment situation, and such a provision is necessary, we believe, to ensure that our total employment package for executives remains market competitive and is consistent with best industry practices. For additional details on our severance and change-in-control arrangements, see “Employment and Severance Agreements” and “Potential Payments Upon Termination or Change-in-Control.”

The Company provides all employees, including executive officers, with group medical, dental and disability insurance on a non-discriminatory basis. The employee group as a whole is required to contribute approximately 20% of the premium costs of such policies. The Company has a 401(k) savings and investment plan intended to qualify under Section 401(a) of the Code, for our domestic employees, which permits employee salary reductions for tax-deferred savings purposes pursuant to Section 401(k) of the Code. During the year ended December 31, 2024, the Company matched 50% of domestic employee contributions up to the first 8% of compensation.

The factors considered by the Compensation Committee in determining the compensation of the Company’s Named Executive Officers, in addition to the criteria discussed above, include the Company’s operating and financial performance, as well as the individual’s leadership and establishment and implementation of the strategic direction for the Company. The Compensation Committee considered as part of its subjective evaluation, among other factors, such executive’s reputation, and contacts in the business community. The compensation of the Company’s Named Executive Officers in 2024 consisted primarily of a base salary, performance-based cash bonus awards, and RSU awards. The total compensation package of the chief executive officer was established considering compensation of peer chief executive officers with similar executive responsibilities.

The Board, and Compensation Committee, has reviewed our compensation policies as generally applicable to our employees and believes that our policies do not encourage excessive and unnecessary risk-taking, and that the

level of risk that they do encourage is not reasonably likely to have a material adverse effect on us. Our management team regularly assesses the risks arising from our compensation policies and practices. The team reviews and discusses the design features, characteristics, performance metrics at the company and segment levels and approval mechanisms of total compensation for all employees, including salaries, incentive plans, and equity-based compensation awards, to determine whether any of these policies or programs could create risks that are reasonably likely to have a material adverse effect on us.

The Company’s compensation policies and practices for its employees, including its executive compensation program described in Compensation Overview, aim to provide a risk-balanced compensation package which is competitive in our market sectors and relevant to the individual executive. The Company expects to continue to award to certain executives and employees, upon satisfaction of applicable performance conditions and subject to future approval and grant by the Board, equity and cash-based awards. Because the incentive plans provide for a blend of short-term and long-term goals, and include substantial vesting features, the Company believes that the structure of its compensation plans discourages short-term risk taking and aligns the interest of its executives and managers with those of its stockholders. The Company does not believe that risks arising from these practices, or its compensation policies and practices considered as a whole, are reasonably likely to have a material adverse effect on the Company.

The following table sets forth, for fiscal years 2024 and 2023, a summary of the annual and long-term compensation for services in all capacities of the named executive officers.

The following table shows the number of shares of Common Stock covered by unvested Restricted Stock and RSUs - held by the Company’s named executive officers on December 31, 2024.

The table below shows the number of shares of Common Stock acquired during 2024 upon the vesting of Restricted Stock and RSUs.

On April 14, 2023, the Board, upon the recommendation of the Compensation Committee, approved the Climb Global Solutions, Inc. Executive Severance and Change in Control Plan (the “Severance Plan”) to more closely align the Company’s executive officer severance practices with market practices, including changing “change in control” equity award vesting from single trigger to double trigger for all outstanding and future equity awards. The Severance Plan supersedes and replaces all other employment and severance arrangements and agreements between the Company and its executive officers.

The Severance Plan provides severance benefits upon a qualifying termination of employment (“Covered Termination”) of eligible participants, who will consist of Climb’s and its affiliates’ executives who have been

designated to participate in the Severance Plan (“Eligible Executive”). The Severance Plan provides for three tiers of severance benefits in the event of a Covered Termination, with relative benefits tied to the individual’s seniority. A Covered Termination is an involuntary termination by the Company without “cause” (and other than as a result of death or disability) or a resignation by the Eligible Executive for “good reason” (each such term as defined in the Severance Plan).

Severance Benefits of Eligible Executive Following Covered Termination Outside Change in Control Period

If an Eligible Executive experiences a Covered Termination outside of the Change in Control Period (as such term is defined in the Severance Plan), subject to execution of a release of claims, she or he will be eligible to receive:

Severance Benefits of Eligible Executive Following Covered Termination Within Change in Control Period

If a Covered Termination occurs, however, during a Change in Control Period (i.e., the period commencing 60 days prior to consummation of a Change in Control and ending 12 months after consummation of a Change in Control), an Eligible Executive will be eligible to receive:

Further, amounts or severance benefits provided to an Eligible Executive under the Severance Plan will be subject to recoupment by the Company in accordance with any clawback policy of the Company, as in effect from time to time.

The Eligible Executive’s right to receive the payments and benefits provided under the Severance Plan are subject to each Eligible Executive’s execution and delivery of a release of claims, and each Eligible Executive’s compliance with non-competition, non-disparagement, non-solicitation and confidentiality covenants set forth in the Severance Plan. The non-disparagement and confidentiality covenants each have an indefinite term, and the non-competition and non-solicitation covenants each has a term of one year following the Eligible Executive’s date of termination, or if longer, the Severance Period or Change in Control Period. Additionally, the Severance Plan provides that if an Eligible Executive would be subject to an excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended, then the payments and benefits the Eligible Executive receives will be reduced so that the excise tax does not apply; however, such reduction will only occur if it results in the receipt by the Eligible Executive of a greater after-tax amount than would otherwise have been received if the full payment had been provided and the excise tax applied.

In order to be eligible to receive benefits under the Severance Plan, the Company’s executive officers must execute and return to the Company a participation agreement (a “Participation Agreement”). Upon the execution of a Participation Agreement, the executive’s prior employment agreement terminates, and the continued employment of such executive will be on an at-will basis. Each of our named executive officers are currently participants in the Severance Plan. Mr. Foster has been designated as a “Tier 1” Participant under the Severance Plan, and Messrs. Clark, Bass and Legrottaglie have been designated as “Tier 2” Participants under the Severance Plan.

In connection with the adoption of the Severance Plan, the Board approved new forms of Cash-Based Award Agreement, Restricted Stock Unit Award Agreement and Performance-Based Restricted Award Unit Agreement (the “Award Agreements”) under the 2021 Plan. The form of Cash Based Award Agreement governs the grants of annual cash bonuses upon the satisfaction of performance goals set by the Board or the Compensation Committee. The form of Restricted Stock Unit Award Agreement provides for the grants of time-based RSUs that will vest based on the grantee continuedly remaining in a Service Relationship (as such term is defined in the Plan) with the Company or a subsidiary thereof through an applicable vesting date(s) to be set by the Board, or the Compensation Committee. Vested RSUs will be settled into shares of Common Stock within 30 days following each vesting date. The form of Performance-Based Restricted Award Unit Agreement provides for the grants of performance-based restricted stock units that will vest based upon the satisfaction of performance goals over a performance cycle set by the Board, or the Compensation Committee, and the grantee continuedly remaining in a Service Relationship with the Company or a subsidiary thereof through the first January 1 following the last day of the performance cycle. Vested PSUs will be settled into shares of Common Stock within 30 days following the vesting date.

The following table illustrates the payments that would have been due to the NEOs in the event they experience a qualifying termination of employment without a change in control and in conjunction with a change in control. Payments are calculated in accordance with the Severance Plan and individual award agreements in place on December 31, 2024, as if each employee was terminated without cause on December 31, 2024.

The accelerated vesting on restricted stock amounts above include unvested restricted stock grants and unvested RSU grants through December 31, 2024, valued at the closing stock price of $126.75 on December 31, 2024. The amounts exclude stock grants made in 2025 to the NEOs.

As previously noted, on January 9, 2025, the Board and Andrew Clark, the Company’s then Chief Financial Officer, mutually agreed that Mr. Clark will resign from his positions as Chief Financial Officer and Vice President of the Company, effective as of January 10, 2025. In consideration for Mr. Clark’s release and waiver of claims

against the Company and the provision of consulting services to the Company until April 15, 2025, the Company has agreed to the following payments and benefits in lieu of any other benefits and payments that may have been due to Mr. Clark under the Climb Global Solutions, Inc. Executive Severance and Change in Control Plan: (i) cash compensation for his services as a consultant in the amount of $86,794.52, payable in three equal amounts on February 14, 2025, March 14, 2025, and April 15, 2025; (ii) $8,159.10 for the cost of COBRA health insurance from February 1, 2025 through April 30, 2025; (iii) the vesting of 4,889 time-vested shares and restricted stock units if he continues his service as a consultant through April 15, 2025, which represents restricted stock units that he had been previously granted and were scheduled to vest during his consulting period; (iv) the vesting of 7,356 restricted stock units granted pursuant to Mr. Clark’s existing performance awards, if Mr. Clark performs the consulting services through April 15, 2025, the goals for which were waived and these would vest upon the completion of the consulting period. All non-vested equity awards will be forfeited on April 15, 2025. The separation agreement entered into provides Mr. Clark will receive his bonus payment earned for the year 2024 in the amount of $337,500.

As described in more detail in the section titled “Compensation Overview,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the table above. Further, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with ‘compensation actually paid’ for a particular year (as computed in accordance with Item 402(v) of Regulation S-K).

In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between the information presented in the table above. Compensation Actually Paid and Company TSR.

The Dodd-Frank Wall Street Reform and Consumer Protection Act requires us to obtain an advisory vote (non-binding) from our stockholders on our executive compensation as disclosed in this proxy statement, which is often referred to as a “say on pay” proposal. At the 2019 Annual Meeting of Stockholders, the stockholders approved that a vote on “say on pay” should be sought annually, and we are conducting “say on pay” advisory votes (non-binding) in accordance with such schedule.

We are asking that our stockholders indicate their support of our executive compensation as described in this proxy statement. While this advisory vote on executive compensation is non-binding, our Board and the Compensation Committee will review the outcome of this vote and take the vote into consideration when reviewing our compensation policies and procedures which have been adjusted in response to input received from stockholders over the past year. This is not intended to address specific items of compensation, but rather the overall compensation of our named executive officers and our executive compensation policies and procedures as described in this proxy statement.

At the Meeting we will ask our stockholders to approve the following resolution:

“RESOLVED, that the Company’s stockholders approve, on a non-binding, advisory basis, the compensation of the named executive officers, as described in the Company’s proxy statement for the 2025 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the 2024 Summary Compensation Table and the other compensation related tables and disclosure.”

The Dodd-Frank Act requires us to obtain an advisory vote (non-binding) from our stockholders indicating how frequently we should seek an advisory vote on our executive compensation, such as Proposal 2 included on page 31 of this proxy statement. By voting on this Proposal 3, stockholders may indicate whether they would prefer an advisory vote on our executive compensation at the annual meeting of stockholders every one, two, or three years.

After careful consideration of this proposal, our Board has determined that an advisory vote on executive compensation that occurs every year is the most appropriate alternative for us, and therefore our Board recommends that you vote for an advisory vote on executive compensation every year.

In formulating its recommendation, our Board considered that an annual advisory vote on our executive compensation will not only provide our stockholders with direct input on our executive compensation, but also will allow stockholders, our management and our Board time to evaluate the effects of our executive compensation policies and procedures. This approach will further provide us with time to implement improvements and changes to address any concerns reflected by a negative vote.

You may cast your vote for your preferred voting frequency by choosing the option of one year, two years, or three years or abstain from voting when you vote in response to the resolution set forth below:

“RESOLVED, that the stockholders of the Company determine on an advisory basis, that the frequency with which the stockholders of the Company shall have an advisory vote on the compensation of the Company’s Named Executive Officers as set forth in the Company’s proxy statement is Option 1 - once every year, Option 2 - once every two years, Option 3 - once every three years, or Option 4 - abstain from voting.”

Although this vote is advisory and not binding, the Board will carefully review the results of the vote in making the determination as to the frequency of future advisory votes on our executive compensation.

Our independent registered public accounting firm during the year ended December 31, 2024 was Deloitte. Deloitte has served as the Company’s independent registered public accounting firm since 2024. Prior to 2024, BDO USA, P.C. (“BDO”) was our independent registered public accounting firm for the year ended December 31, 2023. BDO had served as the Company’s independent registered public accounting firm from 2018 through 2024. On March 6, 2024, the Audit Committee notified BDO that they were dismissed as our independent registered public accounting firm, effective immediately.

The audit reports of Deloitte and BDO on the consolidated financial statements of the Company for each of the two most recent fiscal years ended December 31, 2024 and December 31, 2023 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles.

In accordance with Item 304(a)(3) of Regulation S-K under the Exchange Act, the Company provided BDO with a copy of the disclosure made by the Company in response to Item 4.01 in the Company’s Current Report on Form 8-K prior to its filing with the SEC on March 11, 2024, and requested that BDO furnish it with a letter addressed to the SEC stating whether it agrees with the statements made by the Company in response to Item 4.01. A copy of BDO’s letter, dated March 7, 2024, is filed as Exhibit 16.1 to our Current Report on Form 8-K, filed with the SEC on March 11, 2024.

Also on March 6, 2024, the Audit Committee approved the engagement of Deloitte to serve as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. While we are not required to have the stockholders ratify the selection of Deloitte as our independent registered public accounting firm, we are doing so because we believe it is a matter of good corporate practice. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether or not to retain Deloitte; however, the Audit Committee will not be under any obligation to adhere to the stockholders’ vote on this proposal, and in its full discretion may choose to maintain Deloitte as the Company’s independent registered public accounting firm. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders.

During the Company’s two most recent fiscal years ended December 31, 2023 and December 31, 2022 prior to BDO’s dismissal and during the subsequent interim period from January 1, 2024 through March 6, 2024, (i) there were no disagreements with BDO on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures that, if not resolved to BDO’s satisfaction, would have caused BDO to make reference to the subject matter of the disagreement in connection with its reports and (ii) there were no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

During the Company’s two most recent fiscal years ended December 31, 2023 and December 31, 2022 prior to BDO’s dismissal, and for the subsequent interim period through March 6, 2024, neither the Company nor anyone on its behalf consulted Deloitte regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the consolidated financial statements of the Company, in connection with which neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K or a reportable event as described in Item 304(a)(1)(v) of Regulation S-K under the Exchange Act.

One or more representatives of Deloitte are expected to be present at the Meeting and they will have the opportunity to make a statement and will be available to respond to appropriate questions.

The following table sets forth the fees billed by Deloitte and BDO for the fiscal years ended December 31, 2024, and 2023 for the categories of services indicated.

The Audit Committee pre-approves all audit and permissible non-audit services performed by our independent registered public accounting firm and audit engagement fees and terms in order to ensure that the provision of such services does not impair such accounting firm’s independence.

All audit, audit-related, tax, and other services were pre-approved by the Audit Committee, which concluded that the provision of such services by Deloitte and BDO was compatible with the firm’s independence in the conduct of its auditing functions. The Audit Committee has taken into consideration whether the provision of non-audit services by Deloitte and BDO is compatible with maintaining auditor independence. None of the services described above was approved pursuant to the de minimis exception provided in Rule 2-01(c)(7)(i)(C) of Regulation S-X promulgated by the SEC.

The Company does not know of any matters other than those stated in this proxy statement which are to be presented for action at the Meeting. If any other matters should properly come before the Meeting, proxies will be voted on these other matters in accordance with the discretion of the persons voting the proxies. Discretionary authority to vote on such matters is conferred by such proxies upon the persons designated therein as proxy appointees, to the extent authorized under Rule 14a-4(c) under the Exchange Act.

The Company has adopted a written policy whereby all transactions between the Company and each related person (as defined in Item 404 of Regulation S-K) or in which any related person had or will have a direct or indirect material interest must be on terms no less favorable to the Company than could be obtained from unrelated third parties and require pre-approval by a majority of the disinterested members of the Board.

The Company made sales to a customer where a family member of one of our executives has a minority ownership position. The minority ownership position terminated during the year ended December 31, 2024. During the year ended December 31, 2024 and 2023, net sales to this customer totaled approximately $0.7 million and $1.4 million, respectively, and amounts due from this customer as of December 31, 2024 and 2023 were zero and less than $0.1 million, respectively, which was settled in cash subsequent to the period end.

These transactions were on terms no less favorable to the Company than could be obtained from unrelated third parties.

In the course of fulfilling its responsibilities during fiscal year 2024, the Audit Committee of our Board has:

Based on the foregoing, the Audit Committee recommended to the Board that the audited financial statements referred to above be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, for filing with the SEC.

Based solely on our review of such forms furnished to us or written representations provided to us by the reporting persons, we believe that all filing requirements applicable to our executive officers, directors and other persons who beneficially own more than 10% of a registered class of our equity securities were complied with in the year ended December 31, 2024, except that a Form 4, covering one delinquent transaction on March 11, 2024, was inadvertently filed late by Charles Bass on March 19, 2024.

The SEC has adopted rules that permit companies and intermediaries (such as brokers and banks) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

Beneficial owners of Common Stock who share a single address may receive only one copy of the Notice of Annual Meeting of Stockholders, proxy statement and 2024 Annual Report, as the case may be, unless their broker, bank or

nominee has received contrary instructions from one or more of the affected stockholders at that address. Once a stockholder has received notice from its bank or broker that it will be householding communications to the stockholder’s address, householding will continue until the stockholder is notified otherwise or until such stockholder revokes its consent. If, at any time, any beneficial shareowner(s) at such an address wish to discontinue householding and would prefer to receive a separate copy of the Notice of Annual Meeting of Stockholders, proxy statement and 2024 Annual Report, as the case may be, or if they currently receive multiple copies at the same address and wish to receive only a single copy in the future, they may notify their bank or broker and direct their request to Broadridge, either by calling (800) 579-1639, or by writing to Broadridge, Household Department, 51 Mercedes Way, Edgewater, New York, 11717.

Any stockholder proposal to be considered by us for inclusion in the Company’s proxy statement and form of proxy card for the 2026 Annual Meeting of Stockholders pursuant to Rule 14a-8 of the Exchange Act, must be received by the Corporate Secretary at the Company’s principal executive offices located at 4 Industrial Way West, 3rd Floor, Eatontown, New Jersey 07724, no later than December 30, 2025 (120 calendar days prior to the first anniversary of the date this proxy statement was first released to our stockholders). However, if the date of the 2026 Annual Meeting of Stockholders is advanced or delayed by more than 30 days from the first anniversary of the date of the Meeting, then the deadline is a reasonable time before the Company begins to print and send its proxy materials for the 2026 Annual Meeting of Stockholders.

Any director nomination or proposal that a stockholder wishes to present at the 2026 Annual Meeting of Stockholders, other than through inclusion in the Company’s proxy statement pursuant to Rule 14a-8 of the Exchange Act, must follow the procedures described in our Certificate of Incorporation and Bylaws. Under these procedures, stockholders must submit the nomination or proposal by giving notice to our Secretary at our principal executive office not later than the earlier to occur of (x) the date that is 60 days prior to the 2026 Annual Meeting of Stockholders and (y) December 30, 2025, which is the deadline for stockholder proposals to be submitted for inclusion in the Company’s proxy materials for the 2026 Annual Meeting of Stockholders. However, if notice or public disclosure of the date of the 2026 Annual Meeting of Stockholders occurs less than 60 days prior to the meeting, any director nomination or proposal by a stockholder, to be timely, must be received by the Company not later than the close of business on the tenth day following the day on which such notice of the meeting date was furnished or such public disclosure was made, whichever occurs first. The stockholder’s notice must set forth the information required under Article V Section 5 of our Certificate of Incorporation. A copy of our current Certificate of Incorporation and Bylaws can be obtained free of charge from our Corporate Secretary who can be reached at the Company’s principal executive offices located at 4 Industrial Way West, 3rd Floor, Eatontown, New Jersey 07724.

In addition, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than our nominees for our annual meeting to be held in 2026 must give timely notice to the Company that complies with the additional requirements of Rule 14a-19(b) under the Exchange Act no later than April 6, 2026. We reserve the right to reject, rule out of order, or take other appropriate action with respect to any director nomination that does not comply with these requirements, our Bylaws or other applicable requirements.
