You are cordially invited to attend the Annual Meeting of Stockholders (the “Annual Meeting”) of PDS Biotechnology Corporation, a Delaware corporation (the “Company”, “PDS”, or “PDS Biotech”). The Annual Meeting will be held on June 24, 2024, at 9 a.m. Eastern Time. The Annual Meeting will be held virtually via live webcast. Stockholders will be able to attend the Annual Meeting and submit questions and vote their shares during the Annual Meeting from any location that has internet connectivity. There will be no physical in-person meeting. You or your proxyholder will be able to participate and vote by visiting www.virtualshareholdermeeting.com/PDSB2024 and entering your 16-digit control number (included in the Notice of Internet Availability of Proxy Materials that will be mailed to you). To register and receive access to the virtual meeting, registered stockholders and beneficial stockholders (those holding shares through a stock brokerage account or by a bank or other holder of record) will need to follow the instructions applicable to them provided in the enclosed proxy statement. The Annual Meeting will be held for the following purposes:

These items of business are more fully described in the proxy statement accompanying this notice. Any action on the items of business described above may be considered at the Annual Meeting at the time and on the date specified above or at any time and date to which the Annual Meeting may be properly adjourned or postponed. The record date for the Annual Meeting is April 26, 2024 (the “Record Date”). Only stockholders of record at the close of business on that date may vote at the Annual Meeting or any adjournment thereof.

This Notice of Annual Meeting and Proxy Statement are first being distributed or made available, as the case may be, on or about April 29, 2024. In accordance with the Securities and Exchange Commission rules allowing companies to furnish proxy materials to their stockholders over the Internet, we have sent stockholders of record at the close of business on the Record Date a Notice of Internet Availability of Proxy Materials. The notice contains instructions on how to access our Proxy Statement and Annual Report and vote online. If you would like to receive a printed copy of our proxy materials from us instead of downloading a printable version from the Internet, please follow the instructions for requesting such materials included in the notice, as well as in the attached Proxy Statement. You are cordially invited to attend the meeting via the Internet. Whether or not you expect to attend the meeting, please vote over the telephone, on the Internet as instructed in these materials, or, if you receive a paper copy of the proxy card by mail, by returning your signed proxy card in the envelope provided as promptly as possible in order to ensure your representation at the meeting. Voting instructions are printed on your proxy card and included in the accompanying proxy statement. Even if you have voted by proxy, you may still vote online if you attend the meeting via the Internet. To vote online at the Annual Meeting, please follow the instructions at www.virtualshareholdermeeting.com/PDSB2024. You will need the 16-digit control number, which is included in the Notice of Internet Availability of Proxy Materials.

We have made these proxy materials available to you on the Internet or, upon your request, have delivered paper proxy materials to you, because our board of directors (the “Board”) is soliciting your proxy to vote at the Annual Meeting to be held on Monday, June 24, 2024 at 9 a.m. Eastern Time, and at any adjournment or postponement thereof, for the purpose of considering and acting upon the matters set forth herein. This proxy statement includes information that we are required to provide to you by the Securities and Exchange Commission (“SEC”), and that is designed to assist you in voting your shares.

The rules of the SEC permit us to furnish proxy materials, including this Proxy Statement and our 2023 Annual Report, to our stockholders by providing access to such documents on the Internet instead of mailing printed copies. As a result, we are mailing most of our stockholders a paper copy of the Notice, but not a paper copy of the proxy materials. This process allows us to provide our proxy materials to our stockholders in a timelier and more readily accessible manner, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials. Stockholders will not receive paper copies of the proxy materials unless they request them. Instead, the Notice of Internet Availability of Proxy Materials (the “Notice and Access Card”) provides instructions on how to access and review on the Internet all of the proxy materials. The Notice and Access Card also instructs you as to how to authorize via the Internet or telephone your proxy to vote your shares according to your voting instructions. If you would like to receive a paper or email copy of our proxy materials, you should follow the instructions for requesting such materials described in the Notice and Access Card.

We are providing stockholders who have previously requested to receive paper copies of the proxy materials with paper copies of the proxy materials instead of the Notice and Access Card. If you would like to reduce the environmental impact and the costs incurred by us in printing and distributing the proxy materials, you may elect to receive all future proxy materials electronically via email or the Internet. To sign up for electronic delivery, please follow the instructions provided with your proxy materials and on your proxy card or voting instruction card.

The proxy materials include:

The Annual Meeting will be held on June 24, 2024, at 9 a.m. Eastern Time via a virtual stockholder meeting through which you can listen to the meeting, submit questions and vote online. The Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/PDSB2024 and entering your 16-digit control number which is

included in the Notice and Access Card that will be mailed to you. The virtual meeting platform is fully supported across browsers and devices running the most updated version of applicable software and plugins. Participants should ensure that they have a strong Internet connection wherever they intend to participate in the meeting.

We recommend that you log in a few minutes before the Annual Meeting on June 24, 2024, to ensure you are logged in when the meeting starts. Online check-in will begin at 8:55 a.m. Eastern Time.

Stockholders participating in the virtual meeting may submit questions or comments to the Company’s officers during the meeting.

If you would like to submit a question, you may do so by joining the virtual Annual Meeting at www.virtualshareholdermeeting.com/PDSB2024 and typing your question in the box in the Annual Meeting portal.

To help ensure that we have a productive and efficient meeting, and in fairness to all stockholders in attendance, you will also find posted our rules of conduct for the Annual Meeting when you log in prior to its start. In accordance with the rules of conduct, we ask that you limit your remarks to one brief question or comment that is relevant to the Annual Meeting or our business and remarks that are respectful of your fellow stockholders and meeting participants. Questions may be grouped by topic by our management with a representative question read aloud and answered. In addition, questions may be ruled as out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the speaker’s own personal, political or business interests. Questions will be addressed in the Q&A portion of the Annual Meeting, as time permits.

If you encounter any difficulties accessing the virtual Annual Meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Stockholder Meeting login page. Technical support will be available starting at 8:55 a.m. Eastern Time on June 24, 2024.

Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the Record Date, there were [   ] shares of common stock outstanding and entitled to vote.

If on the Record Date your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.

If on the Record Date your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy from your broker or other agent.

There are four matters scheduled for a vote:

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

Whether you hold shares directly as the stockholder of record or indirectly as the beneficial owner of shares held for you by a broker or other nominee (i.e., in “street name”), you may direct your vote without attending the Annual Meeting. You may vote by granting a proxy or, for shares you hold in street name, by submitting voting instructions to your broker or nominee. In most instances, you will be able to do this by internet, telephone or by mail. Please refer to the summary instructions below and those included on your proxy card or, for shares you hold in street name, the voting instruction card provided by your broker or nominee.

The procedures for voting are as follows:

If you are a stockholder of record, you may vote at the Annual Meeting, vote by proxy over the telephone, vote by proxy through the internet, or vote by proxy using a proxy card that you may request or that we may elect to deliver to you. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted.

If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received a notice containing voting instructions from that organization rather than from us. Simply follow the voting instructions in the notice to ensure that your vote is counted. Alternatively, you may vote by telephone or on

the Internet as instructed by your broker or bank. To vote online at the Annual Meeting, please follow the instructions at www.virtualshareholdermeeting.com/PDSB2024. You will need the 16-digit control number, which is included in the Notice and Access Card that will be mailed to you. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the Annual Meeting and vote online even if you have already voted by proxy.

Internet proxy voting is provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your Internet access, such as usage charges from Internet access providers and telephone companies.

No. The Notice and Access Card will, however, provide instructions on how to vote by telephone, by internet, by requesting and returning a paper proxy card or voting instruction card, or by submitting a ballot at the Annual Meeting.

On each matter to be voted upon, you have one vote for each share of common stock you owned as of the Record Date.

If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the Internet or at the Annual Meeting, your shares will not be voted.

See “What are broker non-votes?” below.

If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted,

If any other matter is properly presented at the Annual Meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

We will pay for the entire cost of soliciting proxies as well as hosting the virtual-only Annual Meeting. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the reasonable cost of forwarding proxy materials to beneficial owners. In addition, we have engaged Morrow Sodali to assist in the solicitation of proxies and provide related advice and information support, for a fee that is not expected to exceed $40,000 in total.

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted.

Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting.

If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

Your most current proxy card or telephone or internet proxy is the one that is counted.

If your shares are held by your broker, bank or other agent as a nominee, you should follow the instructions provided by your broker, bank or other agent.

Stockholders may present proper proposals for inclusion in our proxy statement and for consideration at the next Annual Meeting of Stockholders by submitting their proposals in writing to our Secretary in a timely manner. Stockholders who wish to submit a proposal that is intended to be presented for consideration at next year’s annual meeting, or who propose to nominate a candidate for election as a director at that meeting, are required by our bylaws to provide notice of such proposal or nomination no later than the close of business on February 24, 2025, which is the date that is not less than 120 days prior to the first anniversary of the Annual Meeting, but not earlier than the close of business on January 25, 2025, which is the date that is not more than 150 days prior to the first anniversary of the Annual Meeting, to be considered for a vote at next year’s annual meeting. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 regarding the inclusion of stockholder proposals in company-sponsored proxy materials.

Upon receipt of any such proposal, we will determine whether or not to include such proposal in the proxy statement for the 2025 annual meeting of stockholders and proxy in accordance with regulations governing the solicitation of proxies.

To comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees in connection with our 2025 annual meeting must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act.

Any proposal, nomination or notice must contain the information required by our bylaws and be delivered to our principal executive offices at PDS Biotechnology Corporation, c/o Corporate Secretary, 303A College Road, East, Princeton, NJ 08540.

Before the Annual Meeting, our Board will appoint one or more inspectors of election for the meeting. The inspector(s) will determine the number of shares represented at the meeting, the existence of a quorum and the validity and effect of proxies. The inspector(s) will also receive, count, and tabulate ballots and votes and determine the results of the voting on each matter that comes before the Annual Meeting.

Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine.” Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker or nominee holding the shares. If the beneficial owner does not provide voting instructions, the broker or nominee can still vote the shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of Nasdaq, “non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, elections of directors (even if not contested) and executive compensation, including the advisory stockholder votes on executive compensation and on the frequency of stockholder votes on executive compensation.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the Annual Meeting or represented by proxy. Virtual attendance at the Annual Meeting constitutes presence in person for purposes of a quorum at the Annual Meeting. On the Record Date, there were [  ] shares outstanding and entitled to vote. Thus, the holders of [  ] shares must be present at the Annual Meeting or represented by proxy to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote at the Annual Meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, either the chairman of the Annual Meeting or the holders of a majority of shares present at the Annual Meeting or represented by proxy may adjourn the Annual Meeting to another date.

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting.

If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.

If you have questions about the Annual Meeting or would like additional copies of this Proxy Statement, you should contact Spencer Brown at PDS Biotechnology Corporation, 303A College Road East, Princeton, NJ 08540.

Our Board is divided into three classes: Class A, Class B and Class C, with each class serving a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors that may serve on the Board, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

The Board presently has seven members. The two nominees for director this year are Frank Bedu-Addo, Ph.D. and Otis Brawley, M.D. each of whom is a current director. If elected at the Annual Meeting, each of Dr. Bedu-Addo and Dr. Brawley would serve until the 2027 annual meeting or until their successor has been duly elected and qualified, or their earlier death, resignation or removal. No director or nominee for director is related to any other director or executive officer of PDS Biotech or nominee for director by blood, marriage or adoption. Our directors are expected to attend our Annual Meeting via the Internet. There are no arrangements or understandings between any nominee and any other person pursuant to which each such the nominee was selected.

Directors are elected by a plurality of the votes cast of the holders of shares present at the Annual Meeting or represented by proxy and entitled to vote on the election of directors. Accordingly, each of Dr. Bedu-Addo and Dr. Brawley will be elected if they receive a plurality of the votes cast. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of each of Dr. Bedu-Addo and Dr. Brawley. If Dr. Bedu-Addo and Dr. Brawley become unavailable for election as a result of an unexpected occurrence, shares that would have been voted for such person will instead be voted for the election of a substitute nominee proposed by the Board. Dr. Bedu-Addo and Dr. Brawley have each agreed to serve if elected. Our management has no reason to believe that either Dr. Bedu-Addo or Dr. Brawley will be unable to serve.

The following table provides information on the nominees for the position of director of PDS Biotech as of the Record Date and for each director continuing in office after the Annual Meeting.

Dr. Bedu-Addo has served as director, President and Chief Executive Officer of PDS Biotech since March 2019. Dr. Bedu-Addo is a veteran biotech executive with experience successfully starting and growing biotechnology organizations.

Prior to Cardinal Health, Dr. Bedu-Addo was an Associate Director at Akzo-Nobel, Senior Scientist at Elan (The Liposome Co.), and Principal Scientist at Schering-Plough. In these positions, he contributed to the development of numerous drugs, including antiviral and anticancer products. Dr. Bedu-Addo obtained both his M.S. in Chemical Engineering and Ph.D. in Pharmaceutics from the University of Pittsburgh.

The Board believes that Dr. Bedu-Addo’s perspective and experience as our President and CEO, as well as his depth of operating and senior management experience in the pharmaceuticals industry and educational background, provide him with the qualifications and abilities to serve as a director.

The Board believes that Mr. Freitag’s leadership, legal, corporate governance and accounting experiences and knowledge, as well as his familiarity with the life sciences industry and PDS Biotech, provide him with the qualifications and skills to serve as a director.

The Board believes Dr. Iliev’s venture capital and high-growth company experience provides him with the qualifications and skills to serve as a director.

As required under the Nasdaq listing standards, a majority of the members of a listed company’s board of directors must qualify as “independent,” as affirmatively determined by the board of directors. The Board consults with our counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

The Board has undertaken a review of the independence of our directors and has determined that all of our directors, except Frank Bedu-Addo, Ph.D. and Ilian Iliev, Ph.D., are independent within the meaning of Section 5605(a)(2) of the Nasdaq Stock Market listing rules. Dr. Bedu-Addo is not an independent director under these rules because he is our President and Chief Executive Officer, and the Board has determined that Dr. Iliev is not an independent director because of his relationship with NetScientific plc, a current stockholder of the Company.

The Board has appointed Mr. Stephen Glover as Chairman of the Board. The Chairman has the authority, among other things, to preside over Board meetings, to set meeting agendas and to perform all other duties delegated to him from time to time by the Board. We believe that separation of the positions of Board Chairman and Chief Executive Officer reinforces the independence of the Board in its oversight of our business and affairs. In addition, we believe that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in our best interests and the best interests of our stockholders. As a result, we believe that having an independent Chairman can enhance the effectiveness of the Board as a whole.

There are no family relationships among any of our directors or executive officers.

The table below provides certain highlights of the composition of the Board as of the Record Date and such information has remained unchanged since the 2023 annual meeting of stockholders. Each of the categories listed in the below table has the meaning as it is used in Nasdaq Listing Rule 5605(f). The Board is committed to having a diversified board, including diversity of thought, background and experience, and diversity of personal characteristics such as gender identity, race, ethnicity and sexual orientation.

One of the Board’s key functions is informed oversight of our risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight. Our Board is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for us. Our Audit Committee has the responsibility to review and discuss with management and KPMG LLP, the Company’s independent auditors, as appropriate, our guidelines and policies with respect to risk assessment and risk management, including our major financial risk exposures and the steps taken by management to monitor and control these exposures, including as it concerns risks from cybersecurity threats. In general, we seek to address cybersecurity risks through a cross-functional approach that is focused on preserving the confidentiality, integrity, and availability of the information that we collect and store by identifying, preventing, and mitigating cybersecurity threats and effectively responding to cybersecurity incidents when they occur. Our Nominating and Corporate Governance Committee is responsible for developing our corporate governance principles, and periodically reviews these principles and their application. Our Compensation Committee reviews our practices and policies of employee compensation as they relate to risk management and risk-taking incentives, to determine whether such compensation policies and practices are reasonably likely to have a material adverse effect on us.

Each director is expected to make reasonable efforts to attend all Board and applicable committee meetings. Attendance is taken into account by the Nominating and Corporate Governance Committee and the Board when they assess directors for re-nomination to the Board. Each director is also expected to attend our annual stockholder meetings, and five (5) of our current directors attended the 2023 Annual Meeting of Stockholders. The Board met eight (8) times during the year ended December 31, 2023. All directors attended at least 75% of the aggregate number of meetings of the Board and of the committees on which they served during 2023 or the portion thereof for which they were directors or committee members.

The Board has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides membership information as of the Record Date for each of these standing Board committees. From time to time, our Board and committees also take action by written consent without a meeting. Each of our Board committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities.

Our Audit Committee currently consists of Mr. Freitag, Mr. Glover and Ms. Ali-Jackson, each of whom satisfies the independence requirements under The Nasdaq Capital Market listing standards and Rule 10A-3(b)(1) of the Exchange Act. The chairperson of our Audit Committee is Mr. Freitag, whom our Board has determined to be an “audit committee financial expert” within the meaning of SEC regulations. Each member of our Audit Committee can read and understand fundamental financial statements in accordance with Audit Committee requirements. In arriving at this determination, the Board has examined each Audit Committee member’s scope of experience and the nature of their employment in the corporate finance sector. PDS Biotech’s Audit Committee held four (4) meetings in 2023.

The primary purpose of our Audit Committee is to assist the Board in the oversight of the integrity of our accounting and financial reporting process, the audits of our financial statements, and our compliance with legal and regulatory requirements. The functions of our Audit Committee include, among other things:

With respect to reviewing and approving related-party transactions, our Audit Committee reviews related-party transactions for potential conflicts of interests or other improprieties. Under SEC rules, related-party transactions are those transactions to which we are or may be a party in which the amount involved exceeds $120,000, and in which any of our directors or executive officers or any other related person had or will have a direct or indirect material interest, excluding, among other things, compensation arrangements with respect to employment and board membership. Our Audit Committee could approve a related-party transaction if it determines that the transaction is in our best interests. Our directors are required to disclose to the committee or the full Board any potential conflict of interest or personal interest in a transaction that our board is considering. Our executive officers are required to disclose any potential conflict of interest or personal interest in a transaction to the Audit Committee. We also poll our directors and executive officers on an annual basis with respect to related-party transactions and their service as an officer or director of other entities. Whenever possible, the transaction should be approved in advance and if not approved in advance, must be submitted for ratification as promptly as practical.

The Board has adopted a charter for the Audit Committee that complies with SEC and Nasdaq Stock Market listing rules. The charter is available on our website at www.pdsbiotech.com.

Our Compensation Committee currently consists of Mr. Glover, Ms. Ali-Jackson, and Sir Richard Sykes, each of whom our Board has determined to be independent under the Nasdaq listing standards and a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. The chairperson of our Compensation Committee is Stephen Glover. PDS Biotech’s Compensation Committee held two (2) meetings in 2023.

The primary purpose of our Compensation Committee is to assist the Board in exercising its responsibilities relating to compensation of our executive officers and employees and to administer our equity compensation and other benefit plans. In carrying out these responsibilities, this committee reviews all components of executive officer and employee compensation for consistency with its compensation philosophy, as in effect from time to time. The functions of our Compensation Committee include, among other things:

In 2023, the Compensation Committee engaged the compensation consulting firm Radford, which is part of the Rewards Solutions practice at Aon plc, (“Radford”), to assess and make recommendations with respect to the amount and types of compensation to provide our executives and directors. Radford reported directly to the Compensation Committee; however, our Chief Executive Officer consulted with Radford with respect to its assessments of the compensation of executive officers other than the Chief Executive Officer. The Compensation Committee reviewed assessments provided by Radford comparing our compensation to that of a group of peer companies within our industry and met with Radford to discuss compensation of our executive officers and our Board, including the Chief Executive Officer, and to receive input and advice, as needed. The Compensation Committee has considered the adviser independence factors required under SEC rules as they relate to Radford and does not believe Radford’s work in 2023 raised a conflict of interest.

The Compensation Committee uses competitive compensation data from an annual study of peer companies performed by Radford to inform the Compensation Committee’s decisions on overall compensation of our executive officers and directors, as well as specific pay elements. The Compensation Committee applies judgment and discretion in establishing targeted pay levels, taking into account not only competitive market data, but also factors such as Company, business and individual performance, experience, scope of responsibility, criticality and skill sets, leadership potential and succession planning.

The Board has adopted a charter for the Compensation Committee that complies with SEC and Nasdaq Stock Market listing rules. The charter is available on our website at www.pdsbiotech.com.

No member of our Compensation Committee has ever been an executive officer or employee of ours. None of our officers currently serve, or served during 2023, on the compensation committee or board of directors of any other entity that has one or more officers serving as a member of the Board or Compensation Committee.

Our Nominating and Corporate Governance Committee currently consists of Ms. Ali-Jackson, Mr. Freitag and Sir Richard Sykes, each of whom our Board has determined to be independent under the Nasdaq listing standards. The chairperson of our Nominating and Corporate Governance Committee is Ms. Ali-Jackson. PDS Biotech’s Nominating and Corporate Governance Committee held four (4) meetings in 2023.

The primary purpose of our Nominating and Corporate Governance Committee is to assist the Board in promoting our best interests and the best interests of our stockholders through the implementation of sound corporate governance principles and practices. The functions of our Nominating and Corporate Governance Committee include, among other things:

The Board has adopted a charter for the Nominating and Corporate Governance Committee that complies with SEC and Nasdaq Stock Market listing rules. The charter is available on our website at www.pdsbiotech.com.

While the Nominating and Corporate Governance Committee does not have a formal diversity policy, the Nominating and Corporate Governance Committee recommends candidates based upon many factors, including the diversity of their business or professional experience, the diversity of their background and their array of talents and perspectives. We believe that the Nominating and Corporate Governance Committee’s existing nominations process is designed to identify the best possible nominees for the Board, regardless of the nominee’s gender, racial background, religion, or ethnicity. The Nominating and Corporate Governance Committee identifies candidates through a variety of means, including recommendations from members of the Board and suggestions from our management, including our executive officers. In addition, the Nominating and Corporate Governance Committee considers candidates recommended by third parties, including stockholders. The Nominating and Corporate Governance Committee gives the same consideration to candidates recommended by stockholders as those candidates recommended by members of our Board. Nominees should have a reputation for integrity, honesty and adherence to high ethical standards, should have demonstrated business acumen, experience and ability to exercise sound judgments in matters that relate to our current and long-term objectives, should be willing and able to contribute positively to our decision-making process, should have a commitment to understand PDS Biotech and our industry and to regularly attend and participate in meetings of the Board and its committees, should have the interest and ability to understand the sometimes conflicting interests of the various constituencies of PDS Biotech, which include stockholders, employees, customers, creditors and the general public, and to act in the interests of all stockholders, should not have, nor appear to have, a conflict of interest that would impair the nominee’s ability to represent the interests of all our stockholders and to fulfill the responsibilities of a director. Nominees shall not be discriminated against on the basis of race, religion, national origin, sex, sexual orientation, disability or any other basis proscribed by law. The value of diversity on the Board should be considered. The Nominating and Corporate Governance Committee considers director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the criteria set forth above, based on whether or not the candidate was recommended by a stockholder.

We do not have a formal process related to stockholder communications with the Board. However, we strive to ensure that the views of stockholders are heard by the Board or individual directors, as applicable, and that appropriate responses are provided to stockholders in a timely manner. We believe our responsiveness to stockholder communications to the Board has been excellent. If you wish to send a communication to the Board, its chair or the chair of any Board committee, please send your communication to Frank Bedu-Addo, Ph.D., our Chief Executive Officer, at PDS Biotechnology Corporation at 303A College Road East, Princeton, NJ 08540, who will forward all appropriate communications as requested.

We have adopted a Code of Conduct, applicable to all of our employees, executive officers and directors. The Code of Conduct is available on our website at www.pdsbiotech.com. The Nominating and Corporate Governance Committee is responsible for overseeing the Code of Conduct and must approve any waivers of the Code of Conduct for employees, executive officers or directors. We expect that any amendments to the Code of Conduct, or any waivers of its requirements, will be disclosed on our website within four business days of such amendment or waiver.

The following table sets forth information regarding our executive officers as of the Record Date.

Biographies for each of our executive officers are provided below.

Please see Dr. Bedu-Addo’s biography above under the section “Class C Nominees for Election for a Three-Year Term Expiring at the 2027 Annual Meeting.”

We qualify as a smaller reporting company (“SRC”) under SEC rules. As such, for purposes of Executive Compensation, the Company’s named executive officers are determined under rules prescribed for an SRC as noted below. As an SRC, we may elect to omit certain disclosures that are not required under the reporting requirements for SRCs, including providing compensation disclosure and analysis under Item 402(b) of Regulation S-K.

The following table sets forth information for the years ended December 31, 2023 and December 31, 2022 concerning compensation of (i) all individuals serving as our principal executive officer, (ii) our two most highly compensated executive officers, other than our principal executive officer, who were serving as executive officers as of December 31, 2023 and (iii) up to two of our most highly compensated executive officers, other than our principal executive officer, that were not serving as executive officers as of December 31, 2023. We refer to these executives as the named executive officers. In accordance with the rules promulgated by the SEC, certain columns relating to information that is not applicable have been omitted from this table.

Because the biopharmaceutical industry is characterized by a very long product development cycle, including a lengthy R&D period and a rigorous regulatory approval process, including the requirements for multiple phases of human testing and the need to meet a significant number of other government requirements, many of the traditional financial performance metrics, such as product sales, revenues and profits, used to evaluate successful performance are inappropriate for a biopharmaceutical company with a continued development focus, such as PDS Biotech. Instead, the specific performance our Compensation Committee considers when evaluating the compensation of our named executive officers include:

Annual corporate goals are proposed by our senior leadership team at the beginning of each year and approved by our Board of Directors. During the first quarter of each year, our Compensation Committee, with the input of the senior leadership team, evaluates our corporate performance for the prior year against the corporate goals set for that year, and, taking into account other corporate achievements and developments, recommends a corporate performance rating to be approved by our Board of Directors.

During the first quarter of each year, our Compensation Committee typically evaluates compensation levels for such year of our executive officers, including the amount of each executive officer’s base salary, target annual bonus and annual equity awards, taking into consideration the compensation paid by our peer group, our prior year’s overall corporate performance against the established corporate goals, as well as each individual executive officer’s contributions to achievement of such corporate goals, individual performance and the other factors described above, in making compensation recommendations to our Board of Directors. Our Board of Directors considers these recommendations in determining the compensation for our executive officers for the applicable year.

The compensation of our named executive officers consists of base salary, annual cash bonuses and equity awards, as well as employee benefits that are made available to our salaried employees generally. Our named executive officers are also entitled to compensation and benefits upon certain terminations of employment, including following a change of control transaction, as described under “Employment Agreements” below.

On March 14, 2022, we entered into new employment agreements with our named executive officers in substantially similar form in order to provide consistency among our executive officers. The terms of the new employment agreements are summarized below. The form of employment agreement was reviewed by our Board of Directors and by the Compensation Committee’s independent compensation consultant to determine whether its provisions are consistent with the employment agreements of our benchmarking peer group. In March 2022, the form of employment agreement was approved by the Compensation Committee, both for use as a form and with respect to the specific terms applicable to each executive officer. Although we believe that each company in our benchmarking peer group understandably has forms of employment agreements that are different from ours, we believe key employment contract provisions covering our executive officers are in line with market practice and provide terms designed to attract and retain executive officers.

Effective as of January 22, 2024, Dr. Wood retired from her position as Chief Medical Officer of the Company. On November 21, 2023, Mr. Hill submitted his resignation, effective December 1, 2023, as Chief Financial Officer, Principal Financial Officer and Principal Accounting Officer of the Company. Pursuant to the terms of their respective employment agreements, neither Mr. Hill nor Dr. Wood received severance in connection with their resignation and retirement, respectively.

We pay our named executive officers a base salary to compensate them for the satisfactory performance of services rendered to the Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. Base salaries for our named executive officers have generally been set at levels deemed necessary to attract and retain individuals with superior talent and were originally established in each named executive officer’s employment agreement.

Dr. Bedu-Addo received a base salary of $580,000 in 2023. Dr. Wood received a base salary of $428,000 in 2023. Mr. Hill received a base salary of $366,942 in 2023. Dr. Conn received a base salary of $143,880 in 2023. In 2022, Dr. Bedu-Addo received a base salary of $540,000. In 2022, Dr. Wood received a base salary of $400,000. In 2022, Mr. Hill received a base salary of $350,000. In 2022, Dr. Conn received a base salary of $132,000.

We offer our named executive officers the opportunity to earn annual cash bonuses to compensate them for attaining short-term company and individual performance goals, subject to continued employment through the applicable payment date of such bonus. Each named executive officer has an annual target bonus potential that is expressed as a percentage of his or her annual base salary. The 2023 target bonus potential for each of Dr. Bedu-Addo, Dr. Wood, Mr. Hill and Dr. Conn were as follows:

Our Compensation Committee, based upon the recommendation of our Chief Executive Officer, establishes performance goals each year and, at the completion of the year, generally determines actual bonus payouts after assessing our performance against these goals and each named executive officer’s individual performance and contributions to our achievements. As a result of the requirement to remain employed through the payment date, a 2023 bonus was not awarded to Dr. Wood due to her retirement or Mr. Hill due to his resignation from the Company. Each of Dr. Bedu-Addo and Dr. Conn receive a 2023 performance bonus in March 2024. The Board of Directors determined that Dr. Bedu-Addo and Dr. Conn each achieved 80% of the performance goals for the year ended December 31, 2023.

We have three stockholder-approved equity compensation plans: the 2009 Stock Option Plan, Second Amended and Restated 2014 Equity Incentive Plan and the 2018 Stock Incentive Plan (the “Plans”), which are further described below. We also have an inducement plan, which is further explained below.

We have historically granted stock option awards to named executive officers when they commenced employment with us and have from time to time thereafter made additional grants as, and when, our Board of Directors determined appropriate to recruit, retain or reward particular named executive officers. Our stock option awards have an exercise price at least equal to the fair market value of our common stock on the date of grant and typically vest as to 25% of the underlying shares on the first anniversary of the date of grant and in equal monthly installments over the following 36 months, subject to the holder’s continued employment with us and potential accelerated vesting in certain circumstances, including as described below for our named executive officers in the section titled “Employment Agreements.” Our stock option awards may be intended to qualify as incentive stock options (ISOs) under the Internal Revenue Code.

On December 8, 2020, the Board adopted, subject to stockholder approval, the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Restated Plan”), which amended and restated the Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Incentive Plan”). On May 19, 2023, the Board adopted, subject to stockholder approval, the Third Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the “Third Restated Plan”). At the 2023 annual meeting of stockholders held on July 14, 2023, the stockholders approved the Third Restated Plan, which amended and restated the Restated Plan to increase the total amount of shares authorized for issuance thereunder. The Third Restated Plan is identical to the Restated Plan in all material respects, except, the number of shares of Common Stock authorized for issuance under the Third Restated Plan increased from 4,165,535 to 6,565,535. As of December 31, 2023, there were 3,051,449 shares available for grant under the Thid Restated Plan.

Pursuant to the terms of the Plans, stock options have a term of ten years from the date of grant or such shorter term as may be provided in the option agreement. Unless specified otherwise in an individual option agreement, ISOs generally vest over a four-year term and nonqualified stock options generally vest over a one to five year term. Unless terminated by the Board, the Plans shall continue to remain effective for a term of ten years or until such time as no further awards may be granted and all awards granted under the Plans are no longer outstanding.

On June 17, 2019, our Board adopted the 2019 Inducement Plan (the “Inducement Plan”). The Inducement Plan provides for the grant of non-qualified stock options. The Inducement Plan was recommended for approval by the Compensation Committee of the Board and subsequently approved and adopted by the Board without stockholder

approval pursuant to Rule 5635(c)(4) of the Nasdaq Listing Rules. On December 8, 2020, our Board amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 200,000 shares to 500,000 shares. On May 17, 2022, the Inducement Plan was amended to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan by 600,000 shares. On January 22, 2024, the Inducement Plan was further amended to increase the total number of shares of Common Stock reserved for issuance thereunder from 1,100,000 shares to 2,100,000 shares. The Inducement Plan is administered by the Compensation Committee of the Board. In accordance with Rule 5635(c)(4) of the Nasdaq Listing Rules, non-qualified stock options under the Inducement Plan may only be made to an employee who has not previously been an employee or member of the Board (or any parent or subsidiary of the Company), or following a bona fide period of non-employment by the Company (or a parent or subsidiary of the Company), if he or she is granted such non-qualified stock options in connection with his or her commencement of employment with the Company or a subsidiary and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary. As of December 31, 2023, there were 112,010 shares available for grant under the Inducement Plan.

Our executive officers are eligible to participate in our employee benefit plans and programs, including medical and dental benefits, flexible spending accounts, short- and long-term disability and life insurance, to the same extent as our other full-time employees, subject to the terms and eligibility requirements of those plans. We provide no perquisites or other personal benefits to the named executive officers that are not available to all full-time employees of the Company.

We sponsor a 401(k) defined contribution plan in which our full-time employees may participate, subject to limits imposed by the Internal Revenue Code of 1986, as amended, to the same extent as our other full-time employees. Currently, we match 100% of each our employees’ contributions up to 3% of their salary and 50% of each employees’ contribution between 3% and 5% of their salary for a maximum contribution of 4% of the applicable employee’s salary. Other than the 401(k) plan, we do not provide any qualified or non-qualified retirement or deferred compensation benefits to our employees, including our named executive officers.

PDS Biotech is a party to employment agreements with each of (i) Frank Bedu-Addo, Ph.D., effective October 11, 2018, and as amended and restated on March 14, 2022, and (ii) Gregory Conn, Ph.D., effective June 1, 2019, and as amended and restated on March 14, 2022. PDS Biotech was a party to employment agreements with each of (i) Lauren Wood, M.D., effective as of March 14, 2022, as an amendment and restatement of the Offer Letter dated February 1, 2019, until Dr. Wood’s retirement from the Company effective January 22, 2024, and (ii) Matthew Hill, dated October 18, 2021, as amended and restated on March 14, 2022, until his resignation from the Company effective December 1, 2023.

The initial base salary and target bonus for each executive under their respective employment agreements as effective in 2023 are as follows:

If PDS Biotech terminates Dr. Bedu-Addo’s employment without Cause, he resigns for Good Reason, or Dr. Bedu-Addo’s employment is terminated due to his death, Dr. Bedu-Addo will be entitled to receive accrued benefits including accrued but unpaid salary and bonus, unreimbursed business expenses, and benefits owed under any qualified retirement plan or health and welfare benefit plan (the “Accrued Obligations”), and the following severance benefits: (i) his base salary for twenty-four (24) months; (ii) bonus equal to the greater of (A) the bonus paid in the prior performance year and (B) the bonus that Dr. Bedu-Addo would have earned, for the performance year in which the termination occurs, on a prorated basis through the date which he continued to provide services; (iii) outstanding equity as of the date of the termination will become 100% vested and outstanding options will remain exercisable until the earliest of (A) 18 months following the termination date, (B) the original 10-year expiration date

for the options, and (C) termination of the equity plan; (iv) benefits continuation for twenty-four (24) months, paid as supplemental cash compensation in an amount equal to 1.3 times each payment of the expenses paid by Dr. Bedu-Addo for welfare benefit coverage, and (v) in the event of a termination without Cause or if Dr. Bedu-Addo resigns for Good Reason within ninety (90) days before and twenty-four (24) months following the effective date of a Change in Control (as defined below) (the “Protection Period”), instead of the bonus referenced in clause (ii) above, Dr. Bedu-Addo will receive a bonus equal to his annual performance-based cash bonus. If Dr. Bedu-Addo’s employment is terminated for Cause, based on his Disability, or he resigns for any reason other than for Good Reason, he will only receive the Accrued Obligations.

If PDS Biotech terminates the employment of Dr. Conn without Cause or he resigns for Good Reason, he will be entitled to receive the Accrued Obligations and the following severance benefits: (i) base salary for twelve (12) months; (ii) benefits continuation for twelve (12) months, and (iii) if terminated during the Protection Period, the executive will also receive a bonus equal to their target bonus, and any outstanding equity as of the closing of a Change in Control will become 100% vested if the executive’s outstanding equity is assumed or continued by the surviving entity.

In addition, each of the employment agreements for Dr. Bedu-Addo and Dr. Conn (i) provide that the executive may be eligible for certain grants of equity awards of common stock of PDS Biotech subject to vesting and other terms and conditions of PDS Biotech’s equity plans and an award agreement, subject to approval of the compensation committee, (ii) provide that if any payment or distribution would be nondeductible by PDS for federal income tax purposes because of Section 280G of the Internal Revenue Code, PDS Biotech shall reduce the aggregate present value of the payment only if reducing the payment will provide the executive with a greater net after-tax amount, (iii) provide for certain confidentiality, intellectual property, cooperation, non-competition, non-solicitation and non-disparagement undertakings, and (iii) require the execution and non-revocation of a general release of claims in favor of PDS Biotech as a condition to receipt of severance benefits.

For purposes of the employment agreements for each of Dr Bedu-Addo and Dr. Conn, the capitalized terms referenced above and not defined herein have the meanings ascribed to such terms in the applicable employment agreement.

On November 21, 2023, Mr. Hill submitted his resignation, effective December 1, 2023, as Chief Financial Officer, Principal Financial Officer and Principal Accounting Officer of the Company. Effective as of January 22, 2024, Dr. Wood retired from her position as Chief Medical Officer of the Company. Mr. Hill and Dr. Wood were eligible to receive the same severance benefits as Dr. Conn prior to their termination date. Pursuant to the terms of their respective employment agreements, neither Mr. Hill or Dr. Wood received severance in connection with their resignation and retirement, respectively.

The table below sets forth the number of securities underlying outstanding plan awards for each named executive officer as of December 31, 2023. We have omitted the “Stock Awards” columns because our named executive officers did not have any stock awards outstanding at 2023 year-end.

The following table sets forth information regarding the compensation actually paid to our Chief Executive Officer and our other named executive officers compared to certain performance measures for the years ended December 31, 2023, 2022 and 2021.

The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how we or our Compensation Committee views the link between company performance and our named executive officers’ pay. As a clinical-stage biotech company, our executive compensation program does not utilize the Company’s financial results as the primary indicator to determine executive compensation. We believe that the creation of sustainable long-term stockholder value depends on our ability to successfully advance our pipeline, and ultimately, bring those product candidates to market. Consequently, our Compensation Committee has designed our executive compensation program to incentivize our executive officers to create that value through the discovery and development of a robust and attractive pipeline of drug candidates. In determining the amount of the annual incentive award for each of our executive officers, including each of our named executive officers, the Compensation Committee evaluated the corporate performance objectives that had been established at the beginning of the calendar year as well as other corporate and individual achievements and performance throughout the year. These performance objectives included clinical milestones for our lead product candidates, research and development milestones for our early-stage drug candidates and other business objectives. Additionally, grants of equity awards, primarily stock options, to our executive officers are intended to incentivize future value creation and to align the long-term interests of our executive officers with shareholders. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown.

The “Compensation Actually Paid”, which is presented in the table below, is defined by the SEC and does not reflect amounts actually paid, earned or received by our named executive officers. A significant portion of the “Compensation Actually Paid” amounts shown relate to changes in values of unvested awards over the course of the applicable reporting year. These unvested awards remain subject to significant risk from forfeiture conditions and possible future declines in value based on changes in our share price. The ultimate values actually realized by our named executive officers from unvested equity awards, if any, cannot be determined until the awards fully vest and are exercised or settled, as the case may be.

The following tables reflect the adjustments made to SCT total compensation to compute “Compensation Actually Paid” for our PEO and average for our other NEOs.

The graph below compares the compensation actually paid to our PEO and the average of the compensation actually paid to our remaining NEOs, with our cumulative total shareholder return for the fiscal years ended December 31, 2023, 2022 and 2021. Total Shareholder Return amounts reported in the graph assume an initial fixed investment of $100 on December 31, 2020.

The graph below compares the compensation actually paid to our PEO and the average of the compensation actually paid to our remaining NEOs, with our net loss for the fiscal years ended December 31, 2023, 2022 and 2021.

In June 2019, we adopted a director compensation policy. Pursuant to the policy, the annual retainer for non-employee directors is $40,000 and the annual retainer for the chair of the board of directors is $70,000. This director compensation remained unchanged in 2023. Annual retainers for committee membership are as follows:

These fees are payable in arrears in four equal quarterly installments on the last day of each quarter, provided that the amount of such payment will be prorated for any portion of such quarter that a director is not serving on our board of directors, on such committee or in such position. Non-employee directors are also reimbursed for reasonable out-of-pocket business expenses incurred in connection with attending meetings of the board of directors and any committee of the board of directors on which they serve and in connection with other business related to the board of directors. Directors may also be reimbursed for reasonable out-of-pocket business expenses authorized by the board of directors or a committee that are incurred in connection with attending conferences or meetings with management in accordance with a travel policy, as may be in effect from time to time.

In addition to the above fees, the board of directors may determine that additional committee fees are appropriate and should be payable for any newly created committee of the board of directors.

In addition, we grant to new non-employee directors upon their initial election to the board of directors, an option to purchase 9,000 shares of our common stock at an exercise price equal to the closing price of our common stock on the date of grant. Each of these options has a term of 10 years from the date of the award and 1/3 of these options vest on each of the first, second and third anniversaries of the date of grant, subject to the non-employee director’s continued service as a director. This vesting accelerates as to 100% of the shares upon a change in control of the Company.

Further, on the dates of each of our annual meetings of stockholders, each non-employee director that has served on our board of directors for at least six months automatically receives an option to purchase 9,000 shares of our common stock at an exercise price equal to the closing price of our common stock on the date of the grant and each non-employee director that has served on our board of directors for less than six months shall receive a pro rata share of such options. Each of these options has a term of 10 years from the date of the award and these options will vest in full on the first anniversary of the date of grant, subject to the non-employee director’s continued service as a director, with 100% acceleration of vesting upon a change in control of the Company.

The table below summarizes the compensation paid by PDS Biotech to each non-employee director for the year ended December 31, 2023:

All cash and option awards described in the above table were paid to the Company’s non-employee directors pursuant to the Company’s director compensation policy for non-employee directors, as described in detail above under the heading “Director Compensation.”

PDS Biotech’s corporate responsibility is fundamental to our long-term success. It is also now more than ever important to our stakeholders. We have a commitment to environmental, social and governance (“ESG”) issues.

Environmental Factors: As we continue to expand our operations, we have initiated certain projects to begin tracking our environmental impact, and where feasible, have taken measures to increase our sustainability efforts. Some of our efforts include our commitment to reduce, reuse or recycle where possible or appropriate.

Social Factors: Our future performance depends significantly upon the continued service of our key employees and personnel and our continued ability to attract and retain highly skilled employees. We provide our employees with competitive salaries and bonuses, opportunities for equity ownership, development programs that enable continued learning and growth and a robust employment package that promotes well-being across all aspects of their lives. In addition to salaries, these programs include potential annual discretionary bonuses, stock awards, a 401(k) plan, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, and flexible work schedules, among other benefits. We may take further actions, in compliance with all appropriate government regulations, that we determine to be in the best interest of our employees.

Diversity and Inclusion: We strive to invest in and create ongoing opportunities for employee development in a diverse and inclusive environment in which each team member plays a unique and vital role. It starts at the top, where we have racially diverse directors and a racially diverse Chief Executive Officer. We believe that a diverse workforce not only positively impacts our performance and strengthens our culture, but it also cultivates an essential

pipeline of experienced leaders for management. Hiring for diversity of thought, background and experience, and diversity of personal characteristics such as identity, gender, race, ethnicity and sexual orientation continues to be an area of focus as we grow our company.

Providing a Positive Working Environment For Our People: Managing our people responsibly and respectfully is critical to the ongoing success of our business. We promote safety, health, and wellbeing in the workplace. We strive to equip our people with the right skills to perform their roles, and we provide development initiatives and opportunity for our staff. We recognize their contributions to our business success in a diverse and inclusive environment in which each team member plays a unique and vital role.

Ethics and Corporate Governance: We aspire to maintain the highest ethical standards. All of our employees are required to adhere to our Code of Conduct and Ethics, which provides, among other things, that all of our employees, officers and directors must (i) be truthful and honest both internally and in our business dealings with each other, and (ii) make all decisions responsibly, constructively and equitably without bias as to race, color creed, religion, national origin, sex, marital status, age, veteran’s status or membership in any other protected class or receipt of public assistance.

We will continue to focus on ESG issues during 2024.

Pursuant to our insider trading policy, our employees, executive officers and directors may not (a) hold our securities in a margin account, (b) pledge our securities as collateral for a loan or (c) enter into hedging or monetization transactions or similar arrangements with respect to our securities, in each case without the advance approval of our compliance officer.

Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to securities. In accordance with SEC rules, shares of our common stock which may be acquired upon exercise of stock options or warrants which are currently exercisable or which become exercisable within 60 days of the date of the applicable table below are deemed beneficially owned by the holders of such options and warrants and are deemed outstanding for the purpose of computing the percentage of ownership of such person, but are not treated as outstanding for the purpose of computing the percentage of ownership of any other person. Subject to community property laws, where applicable, the persons or entities named in the tables below have sole voting and investment power with respect to all shares of our common stock indicated as beneficially owned by them.

The following table sets forth information with respect to the beneficial ownership of our common stock as of April 26, 2024, or the Record Date, by (i) each stockholder known by us to be the beneficial owner of more than 5% of our common stock (our only classes of voting securities), (ii) each of our directors and executive officers, (iii) each of our named executive officers and (iv) all of our directors and executive officers as a group. To the best of our knowledge, except as otherwise indicated, each of the persons named in the table has sole voting and investment power with respect to the shares of our common stock beneficially owned by such person, except to the extent such power may be shared with a spouse. To our knowledge, none of the shares listed below are held under a voting trust or similar agreement, except as noted.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o PDS Biotechnology Corporation, 303A College Road East, Princeton, NJ 08540.

The following table contains information about our equity compensation plans as of December 31, 2023.

Other than employment agreements with our named executive officers and other payments made to our named executive officers, all as described below under the section entitled “Executive Compensation,” and compensation paid to directors as described above in the section titled “Director Compensation,” there were no transactions since January 1, 2023 or any currently proposed transactions, to which PDS has been a participant, in which:

Our Audit Committee is charged with the responsibility of reviewing and approving all related person transactions (as defined in SEC regulations), and periodically reassessing any related person transaction entered into by PDS Biotech to ensure continued appropriateness. This responsibility is set forth in our Audit Committee charter. A related party transaction will only be approved if the members of the Audit Committee determine that the transaction is in the best interests of PDS Biotech. If a director is involved in the transaction, he or she will recuse himself or herself from all decisions regarding the transaction. In addition, the Audit Committee will review these transactions under our Code of Conduct, which governs conflicts of interests, among other matters, and is applicable to our employees, officers and directors.

Our Eighth Amended and Restated Certificate of Incorporation, as amended (the “Charter”), currently authorizes us to issue a total of 75,000,000 shares of common stock, with a par value of $0.00033 per share, and 5,000,000 shares of preferred stock, with a par value of $0.00033 per share, for a total of 80,000,000 shares of all classes. In April 2024, the Board approved an amendment to the Charter (the “Authorized Shares Amendment”) to increase the number of shares of authorized common stock from 75,000,000 shares to 150,000,000 shares, subject to stockholder approval.

To be approved, this Proposal 2 must receive “For” votes from the holders of at least a majority of shares present at the Annual Meeting or represented by proxy and entitled to vote on the matter. Abstentions will have the same effect as an “Against” vote. Brokers have discretion to vote as this proposal is considered a “routine” matter. Therefore, we do not expect any broker non-votes on this Proposal 2.

The Board has unanimously determined that the Authorized Shares Amendment is advisable and in the best interests of the company and our stockholders and recommends that our stockholders approve the Authorized Shares Amendment. In accordance with the General Corporation Law of the State of Delaware (the “DGCL”), we are hereby seeking approval of the Authorized Shares Amendment by our stockholders. No other changes to our Charter are being proposed. The Authorized Shares Amendment is not intended to modify the rights of existing stockholders in any material respect. The additional shares of common stock to be authorized pursuant to the proposed Authorized Shares Amendment will be identical to the shares of common stock currently authorized and outstanding under the Charter, none of which have preemptive or similar rights to acquire the newly authorized shares. Under the DGCL, our stockholders are not entitled to appraisal rights with respect to the proposed Authorized Shares Amendment and we will not independently provide stockholders with any such rights.

As of the Record Date, [   ] shares of common stock were issued and outstanding and 9,874,747 shares of common stock are reserved for issuance under our equity plans. Therefore, we currently have only a limited number of authorized shares of common stock available for future issuance. The Board and management believe that the limited number of currently authorized but unissued and unreserved shares of common stock may restrict our ability to respond to our business needs and opportunities. The availability of additional shares of common stock for issuance will afford us flexibility by assuring that there will be sufficient authorized but unissued shares of common stock for business and financial purposes in the future. The additional shares may be used for various purposes without further stockholder approval. These purposes may include raising capital; providing equity incentives to employees, officers or directors; establishing strategic relationships with other companies; expanding our business or product lines through the acquisition of other businesses or products; stock splits and other corporate purposes.

In determining the magnitude of the Authorized Shares Amendment, the Board considered a number of factors, including our historical issuances of shares and potential future needs, our need to issue additional shares in connection with one or more future equity transactions, acquisitions or other strategic transactions and future issuances under equity compensation plans.

As of the date of this proxy statement, we have no current plans, arrangements or understandings regarding the issuance of any additional shares of common stock that would be authorized pursuant to this proposal, and there are no negotiations pending with respect to the issuance thereof for any purpose.

Without an increase in the number of authorized shares of common stock, we may be constrained in our ability to raise capital in a timely fashion or at all and may be unable to complete our clinical programs, commercialize our products, or conduct important business activities, which could adversely affect our financial performance and growth. For example, if the requisite stockholders do not approve this proposal, then we may not have additional shares available or may be required to seek stockholder approval in connection with a transaction, which may delay or otherwise have a material adverse effect on us.

The proposed increase in the number of authorized shares of common stock will not have any immediate effect on the rights of our existing stockholders. However, the Board will have the authority to issue the additional shares of common stock without requiring future stockholder approval of such issuances, except as may be required by applicable law or rules of any stock exchange on which our securities may be listed, including The Nasdaq Stock Market LLC. The issuance of additional shares of common stock may decrease the relative percentage of equity ownership of our existing stockholders, thereby diluting the voting power of their common stock.

While the issuance of additional shares of common stock may be deemed to have potential anti-takeover effects, including by delaying or preventing a change in control through subsequent issuances of these shares and the other reasons set forth above, which, among other things, could include issuances in one or more transactions that would make a change in control more difficult, and therefore, less likely, this proposal to increase the authorized common stock is not prompted by any specific effort of which we are aware to accumulate shares of our common stock or obtain control of our company. A takeover may be beneficial to independent stockholders because, among other reasons, a potential suitor may offer such stockholders a premium for their shares of common stock as compared to the then-existing market price. Although the issuance of additional shares of common stock could, under certain circumstances, have an anti-takeover effect, this proposal is not in response to any effort to which we are aware of to accumulate common stock or obtain control of our company.

The additional authorized shares of common stock, if and when issued, would be part of the existing class of common stock and would have the same rights and privileges as the shares of common stock currently outstanding. Stockholders do not have preemptive rights with respect to our common stock. Therefore, should the Board determine to issue additional shares of common stock, existing stockholders would not have any preferential rights to purchase such shares in order to maintain their proportionate ownership thereof.

We can provide no assurance that we will be successful in amending our Charter to increase the number of shares of common stock that are available for issuance, or that the Authorized Shares Amendment will not have an adverse effect on our stock price.

Our directors and executive officers have no substantial interests, directly or indirectly, in the matters set forth in this proposed amendment, except to the extent of their ownership in shares of our common stock and securities convertible or exercisable for common stock.

The form of the Authorized Shares Amendment is attached as Appendix A to this proxy statement. If this Proposal 2 is approved by our stockholders, the Authorized Shares Amendment will become effective upon the acceptance by the Secretary of State of the State of Delaware of the filing of the Authorized Shares Amendment. Such filing is expected to occur promptly after stockholder approval of this proposal. If this Proposal 2 is not approved, the Charter would remain unchanged and the number of authorized shares of common stock would remain 75,000,000. Other than as described herein, this proposed Authorized Shares Amendment affects no other changes to our Charter.

The Audit Committee has selected KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2024 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Representatives of KPMG LLP are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholder ratification of the selection of KPMG LLP as our independent registered public accounting firm. However, the Audit Committee is submitting the selection of KPMG LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in our best interests and the best interests of our stockholders.

The following table represents aggregate fees billed to PDS Biotech for the fiscal years ended December 31, 2023 and 2022, by KPMG LLP, PDS Biotech’s independent registered public accounting firm.

Audit fees: Audit fees consist of fees associated with the annual audit of our financial statements, the reviews of our interim financial statements, fees consist of fees incurred in connection with the issuance of consent and comfort letters in connection with registration statement filings with the SEC and all services that are normally provided by the accounting firm in connection with statutory and regulatory filings or engagements.

Audit-related fees: Audit-related fees includes fees for services that are traditionally performed by the auditor such as audits of employee benefit plans sponsored by the Company, due diligence assistance, SOC engagements, audits of financial statements of a carve-out entity in anticipation of a subsequent divestiture and other attest services.

Tax fees: Tax fees consist of fees for tax services, including tax compliance, and related expenses.

All KPMG LLP services and fees in the fiscal years ended December 31, 2023 and 2022 were pre-approved by the Audit Committee or its properly delegated authority.

The Audit Committee pre-approves audit and non-audit services rendered by our independent registered public accounting firm, KPMG LLP. The Audit Committee pre-approves specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The pre-approval of services may be delegated to one or more of the Audit Committee’s members, but the decision must be reported to the full Audit Committee at its next scheduled meeting.

If KPMG LLP renders services other than audit services to us, the Audit Committee will determine whether the rendering of these services is compatible with maintaining KPMG LLP’s independence.

The Audit Committee of the Board, which consists entirely of directors who meet the independence and experience requirements of the Nasdaq Capital Market, has furnished the following report:

The Audit Committee assists the Board in overseeing and monitoring the integrity of our financial reporting process, compliance with legal and regulatory requirements and the quality of internal and external audit processes. This committee’s role and responsibilities are set forth in our charter adopted by the Board, which is available on our website at www.pdsbiotech.com. The Audit Committee reviews and reassesses our charter annually and recommends any changes to the Board for approval. The Audit Committee is responsible for overseeing our overall financial reporting process, and for the appointment, compensation, retention, and oversight of the work of independent registered public accountants.

The Audit Committee reviewed and discussed the audited financial statements for the year ended December 31, 2023 with the Company’s management. The Audit Committee has discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board, or PCAOB, and the SEC. The Audit Committee also received the written disclosures and the letter from KPMG LLP, the Company’s independent registered public accounting firm, required by applicable requirements of the by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the PCAOB regarding the independent accountants’ communications with the audit committee concerning independence and has discussed with KPMG LLP the accounting firm’s independence.

Based on the foregoing, the Audit Committee recommended to the Company’s board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.

The foregoing report of the Audit Committee does not constitute soliciting material and shall not be deemed filed, incorporated by reference into or a part of any other filing by the Company (including any future filings) under the Securities Act or the Exchange Act of 1934, as amended, or the Exchange Act, except to the extent the Company specifically incorporates such report by reference therein.

Consistent with good governance practices and the requirements of Section 14A of the Exchange Act, we are asking our stockholders to approve, on a non-binding advisory basis, the compensation of our named executive officers, as disclosed in the “Executive Compensation” section of this proxy statement and the related compensation tables and disclosure. This is commonly referred to as a “say on pay” proposal. We will put forward our next say on pay proposal at the 2025 Annual Meeting of Stockholders.

The say on pay proposal is not intended to address any specific item of compensation or the compensation of any particular officer, but rather the overall compensation of our named executive officers and our compensation philosophy, policies, and practices discussed in this proxy statement. We believe that our executive officer compensation programs provide incentives that are aligned with the interests of our stockholders and have facilitated our performance, business goals and promote short and long term profitable growth. We urge stockholders to read the “Executive Compensation” section above, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation philosophy and objectives, as well as the related compensation tables and narrative above which provide detailed information on the compensation of our named executive officers. Our compensation committee and board of directors believe that the policies and procedures articulated in the “Executive Compensation” section are effective in achieving our goals and that the compensation of our named executive officers reported in this proxy statement has supported and contributed to the Company’s success.

We are asking stockholders to approve the following advisory resolution at the Annual Meeting:

RESOLVED, that the stockholders of PDS Biotechnology Corporation (the “Company”) approve, on an advisory basis, the compensation of the Company’s named executive officers as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission in the compensation tables and related narrative disclosure in this Proxy Statement.

This say on pay proposal, is not binding on our board of directors. Although non-binding, our board of directors and compensation committee will carefully review and consider the voting results when evaluating our executive compensation program.

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for mailing of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single mailing of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are PDS Biotech stockholders will be “householding” our proxy materials. A single mailing of Proxy Materials or other Annual Meeting materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate mailing of Proxy Materials, please notify us or your broker. Direct your written request to Investor Relations, PDS Biotechnology Corporation at 303A College Road East, Princeton, NJ 08540 or by phone at (800) 208-3343. Stockholders who currently receive multiple copies of Proxy Materials at their addresses and would like to request “householding” of their communications should contact their brokers.

The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

This Proxy Statement and our Annual Report to the SEC on Form 10-K for the fiscal year ended December 31, 2023 are available free of charge at www.proxyvote.com.

PDS Biotechnology Corporation, a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Corporation”),

FIRST: The name of the Corporation is PDS Biotechnology Corporation.
