#### PROXY STATEMENT

#### FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### To be Held on August 10, 2026

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### ABOUT THE ANNUAL MEETING

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### QUESTIONS AND ANSWERS ABOUT PROCEDURAL MATTERS

#### Why am I receiving these proxy materials?
We are making these proxy materials available to you on or about June 26, 2026, because our board of directors (the "Board") is soliciting your proxy to vote at the Annual Meeting to be held on Wednesday, August 10, 2026 at 8 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.

#### Why did I receive a notice in the mail regarding the internet availability of proxy materials instead of a paper copy of proxy materials?
The rules of the SEC permit us to furnish proxy materials, including this Proxy Statement and our 2025 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 of Internet Availability of Proxy Materials (the "Notice and Access Card"), 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 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 vote or provide a proxy to vote as instructed via the internet . 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.

#### Why did I receive a complete set of paper proxy materials in the mail instead of a Notice of Internet Availability of Proxy Materials?
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.

#### What is included in the proxy materials?
The proxy materials include:

&nbsp;&nbsp;&nbsp;&nbsp;• This proxy statement for the Annual Meeting;

&nbsp;&nbsp;&nbsp;&nbsp;• PDS Biotech's Annual Report on Form 10-K for the year ended December 31, 2025; and

&nbsp;&nbsp;&nbsp;&nbsp;• The proxy card or a voting instruction form for the Annual Meeting, if you have requested that the proxy materials be mailed to you.

#### How do I attend the Annual Meeting?
The Annual Meeting will be held on August 10, 2026, at 8 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/PDSB2026 and entering your 16-digit control number which is included

------

#### **TABLE OF CONTENTS**
in the Notice and Access Card, proxy card or voting instruction form 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 August 10, 2026, to ensure you are logged in when the meeting starts. Online check-in will begin at 7:55 a.m. Eastern Time.

#### Can I ask questions at the Annual Meeting?
Stockholders participating in the virtual meeting may submit questions or comments 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/PDSB2026 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.

#### What if I need technical assistance accessing or participating in the virtual Annual Meeting?
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 meeting login page. Technical support will be available starting at 7:55 a.m. Eastern Time on August 10, 2026.

#### Who can vote at the Annual Meeting?
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 55,815,653 shares of common stock outstanding and entitled to vote.

*Stockholder of Record: Shares Registered in Your Name* 

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 vote your shares by proxy in advance of the Annual Meeting through the internet, by telephone, or by completing and returning a printed proxy card to ensure your vote is counted.

*Beneficial Owner: Shares Registered in the Name of a Broker, Bank or Other Agent* 

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 and Access Card 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. If your voting instruction form or Notice and Access Card indicates that you may vote your shares through the www.proxyvote.com website, then you may access, participate in, and vote at the Annual Meeting with the 16-digit access code indicated on that voting instruction form or Notice and Access Card. Otherwise, you should contact your broker or other agent (preferably at least five days before the Annual Meeting) and obtain a "legal proxy" in order to log into the Annual Meeting as a shareholder and be able vote at the meeting.

------

#### **TABLE OF CONTENTS**

#### What am I voting on?
There are three matters scheduled for a vote:

Proposal 1: Election of Kamil Ali-Jackson, J.D. and Ilian Iliev, Ph.D. to serve as Class B directors until the 2029 Annual Meeting of Stockholders or until their successors are duly elected and qualified.

#### What if another matter is properly brought before the Annual Meeting?
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.

#### How do I vote?
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 Notice and Access Card, proxy card or, for shares you hold in street name, the voting instruction card provided by your broker or nominee.

*Stockholder of Record: Shares Registered in Your Name* 

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 has been 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.

The Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/PDSB2026 and entering your 16-digit control number which is included in the Notice and Access Card that will be mailed to you. Please have your Notice and Access Card in hand when you access the website and then follow the instructions.

&nbsp;&nbsp;&nbsp;&nbsp;• **By Mail:** You may vote by proxy by filling out the proxy card you may have received and returning it promptly in the envelope provided. If you return your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct.

&nbsp;&nbsp;&nbsp;&nbsp;• **By Telephone:** To vote over the telephone, dial toll-free (800) 690-6903 using a touch-tone phone and follow the recorded instructions. Have your 16-digit control number available when you call. You will be asked to provide the company number and control number from the Notice.

Your internet vote must be received by 11:59 p.m., Eastern Time on August 9, 2026 to be counted.

*Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Agent* 

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

#### **TABLE OF CONTENTS**
as instructed by your broker or bank. To vote online at the Annual Meeting, please follow the instructions at www.virtualshareholdermeeting.com/PDSB2026. You will need the 16-digit control number, which is included in the Notice and Access Card or voting instruction form 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.** 

#### Can I vote my shares by completing and returning the Notice and Access Card?
No. The Notice and Access Card will, however, provide instructions on how to vote over the internet, request a paper copy of the meeting materials, and vote virtually at the Annual Meeting.

#### How many votes do I have?
On each matter to be voted upon, you have one vote for each share of common stock you owned as of the Record Date.

#### What happens if I do not vote?
*Stockholder of Record: Shares Registered in Your Name* 

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.

*Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Agent* 

See "What are broker non-votes?" below.

#### What if I return a proxy card or otherwise vote but do not make specific choices?
If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted,

&nbsp;&nbsp;&nbsp;&nbsp;• "For" the election of each of Kamil Ali-Jackson, J.D. and Ilian Iliev, Ph.D. as directors;

&nbsp;&nbsp;&nbsp;&nbsp;• "For" the approval of an amendment to our Eighth Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized shares of our common stock from 150,000,000 shares to 300,000,000 shares;

&nbsp;&nbsp;&nbsp;&nbsp;• "For" the ratification of the selection of KPMG LLP as our independent registered public accounting firm; and

&nbsp;&nbsp;&nbsp;&nbsp;• "For" the approval of the compensation of our named executive officers.

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.

#### Who is paying for this proxy solicitation?
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.

#### **TABLE OF CONTENTS**

#### What does it mean if I receive more than one Notice and Access Card?
If you receive more than one Notice and Access Card, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each of the notices to ensure that all of your shares are voted.

#### Can I change my vote after submitting my proxy?
Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting.

*Stockholder of Record: Shares Registered in Your Name* 

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

&nbsp;&nbsp;&nbsp;&nbsp;• You may submit another properly completed proxy card with a later date.

&nbsp;&nbsp;&nbsp;&nbsp;• You may grant a subsequent proxy by telephone or through the internet.

&nbsp;&nbsp;&nbsp;&nbsp;• You may send a timely written notice that you are revoking your proxy to our Secretary at PDS Biotechnology Corporation at 303A College Road East, Princeton, NJ 08540.

&nbsp;&nbsp;&nbsp;&nbsp;• You may attend the Annual Meeting via the internet and vote online at the meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy.

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

*Beneficial Owner: Shares Registered in the Name of Broker, Bank or Other Agent* 

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.

#### When are stockholder proposals and director nominations due for next year's annual meeting?
Stockholders may present proper proposals for inclusion in our proxy statement and consideration at the next annual meeting of stockholders in accordance with Rule 14a-8 of the Exchange Act by submitting their proposals in writing to our Secretary no later than February 26, 2027, which is 120 calendar days prior to the first anniversary of the date these proxy materials were sent to our stockholders. Under Rule 14a-8, if the date of the 2027 annual meeting changes by more than 30 days from the anniversary of this year's Annual Meeting, to be included in our proxy statement, stockholder proposals must be received by us within a reasonable time before our solicitation is made.

For any proposal that is not submitted for inclusion in next year's proxy statements, but is instead sought to be presented directly at next year's annual meeting, including director nominations, our bylaws provide that notice of such proposal or nomination no later than the close of business on April 12, 2027, which is the date that is 120 days prior to the first anniversary of the Annual Meeting, but not earlier than the close of business on March 13, 2027, which is the date that is 150 days prior to the first anniversary of the Annual Meeting (or the date that is 10 days following the public announcement of the date of next year's meeting, to the extent that the date is more than thirst days before or more that 60 days after the first anniversary of the Annual Meeting), to be considered for a vote at next year's annual meeting.

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 2027 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.

#### How are votes counted?
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.

------

#### **TABLE OF CONTENTS**

#### What are "broker non-votes?"
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." 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 specific voting instructions, the broker or nominee generally can vote the shares with respect to matters that are considered to be "routine," but not with respect to "non-routine" matters. As described below, we believe that Proposals 2 and 3, the increase in the number of authorized shares of common stock and the ratification of our auditors, respectively, are "routine" matters under applicable rules and regulations. Therefore, without instructions, brokers and other nominees may not vote shares with respect to Proposals 1 and 4. It is therefore important that you act to ensure your shares are voted.

#### How many votes are needed to approve each proposal?
&nbsp;&nbsp;&nbsp;&nbsp;• For the elections of Kamil Ali-Jackson, J.D. and Ilian Iliev, Ph.D. as directors, a plurality of the votes cast will be required for election. Plurality means that the individual who receives the largest number of votes cast "For" is elected as a director, however, a nominee is not required to receive a majority of votes "For". As a result, any shares not voted "For" the nominee (whether as a result of stockholder withholding or a broker non-vote) will not be counted in the nominee's favor.

&nbsp;&nbsp;&nbsp;&nbsp;• To be approved, the approval of an amendment to our Eighth Amended and Restated Certificate of Incorporation, as amended, to increase the number of authorized shares of our common stock from 150,000,000 shares to 300,000,000 must receive "For" votes from the holders of at least a majority of the votes cast at the Annual Meeting and entitled to vote on the matter. Abstentions are not treated as votes cast, and therefore if you "Abstain" from voting, it will have no effect on the vote. Brokers have discretion to vote as this proposal is considered a "routine" matter. Accordingly, if you hold your shares in "street name" and do not provide voting instructions to your broker, bank or other agent that holds your shares, your broker, bank or other agent has discretionary authority to vote your shares on this proposal.

&nbsp;&nbsp;&nbsp;&nbsp;• To be approved, the ratification of the selection of KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026, 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. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Brokers have discretion to vote as this proposal is considered a "routine" matter. Accordingly, if you hold your shares in "street name" and do not provide voting instructions to your broker, bank or other agent that holds your shares, your broker, bank or other agent has discretionary authority to vote your shares on this proposal.

&nbsp;&nbsp;&nbsp;&nbsp;• To be approved, the non-binding advisory resolution on the compensation of our named executive officers, 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. If you "Abstain" from voting, it will have the same effect as an "Against" vote. Broker non-votes will have no effect.

#### What is the quorum requirement?
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.

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.

------

#### **TABLE OF CONTENTS**

#### How can I find out the results of the voting at the Annual Meeting?
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.

#### Who can help answer your questions?
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.

The Board presently has six members. The two nominees for director this year are Kamil Ali-Jackson, J.D. and Ilian Iliev, Ph.D. each of whom is a current director. If elected at the Annual Meeting, each of Ms. Ali-Jackson and Mr. Iliev would serve until the 2029 annual meeting or until their successor has been duly elected and qualified, or their earlier death, resignation or removal. There are no family relationships between any of our directors, executive officers, or nominees for directors. 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 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 Ms. Ali-Jackson and Mr. Iliev 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 Ms. Ali-Jackson and Mr. Iliev. If Ms. Ali-Jackson and Mr. Iliev 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. Ms. Ali-Jackson and Mr. Iliev have each agreed to serve if elected. Our management has no reason to believe that either Ms. Ali-Jackson or Mr. Iliev 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.

#### **TABLE OF CONTENTS**

#### CORPORATE GOVERNANCE

#### Independence of the Board of Directors
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.

#### Board Leadership Structure
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.

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

#### Board Diversity
The Board is committed to having a diversified board, including diversity of thought, background and experience.

#### Role of the Board in Risk Oversight
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.

#### Meetings of the Board of Directors
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

------

#### **TABLE OF CONTENTS**
meetings, and five (5) of our current directors attended the 2025 Annual Meeting of Stockholders. The Board met eleven (11) times during the year ended December 31, 2025. All directors attended at least 75% of the aggregate number of meetings of the Board and of the committees on which they served during 2025 or the portion thereof for which they were directors or committee members.

#### Information Regarding Committees of the Board of Directors
The Board has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides membership information 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.

\* Committee Chairperson

#### Audit Committee
Our Audit Committee currently consists of Mr. Freitag, Mr. Glover and Ms. Ali-Jackson, each of whom satisfies the independence requirements under applicable Nasdaq listing rules 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 2025.

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:

&nbsp;&nbsp;&nbsp;&nbsp;• hiring an independent registered public accounting firm to conduct the annual audit of our financial statements and monitoring its independence and performance;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing potential conflicts of interest under and violations of our Code of Conduct;

With respect to reviewing and approving related-party transactions, our Audit Committee reviews related-party transactions for potential conflicts of interest or other improprieties. Under SEC rules, related-party transactions are those transactions to which we are or may be a participant in which the amount involved exceeds $120,000, and in which

------

#### **TABLE OF CONTENTS**
any of our directors, executive officers or more than 5% stockholders, as well as any family members of the foregoing (each, a "related party") 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 Audit 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, any related party 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.*

#### Compensation Committee
Our Compensation Committee currently consists of Mr. Glover and Ms. Ali-Jackson, 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 four (4) meeting in 2025.

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:

&nbsp;&nbsp;&nbsp;&nbsp;• designing and implementing competitive compensation policies to attract and retain key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and formulating policy and determining the compensation of our executive officers and employees;

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and recommending to the Board the compensation of our directors;

&nbsp;&nbsp;&nbsp;&nbsp;• administering our equity incentive plans and granting equity awards to our employees and directors under these plans;

&nbsp;&nbsp;&nbsp;&nbsp;• if required from time to time, reviewing with management our disclosures under the caption "Executive Compensation" and recommending to the full board its inclusion in our periodic reports to be filed with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;• if required from time to time, preparing the report of the Compensation Committee to be included in our annual proxy statement;

&nbsp;&nbsp;&nbsp;&nbsp;• engaging advisors it deems appropriate to assist with its duties; and

&nbsp;&nbsp;&nbsp;&nbsp;• reviewing and evaluating, at least annually, our Compensation Committee's charter.

The Compensation Committee may review competitive compensation data 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 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 listing rules. The charter is available on our website at *www.pdsbiotech.com.*

#### Compensation Committee Interlocks and Insider Participation
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 2025, 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.

#### Nominating and Corporate Governance Committee
Our Nominating and Corporate Governance Committee currently consists of Ms. Ali-Jackson and Mr. Freitag, 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. Our Nominating and Corporate Governance Committee held four (4) meetings in 2025.

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:

&nbsp;&nbsp;&nbsp;&nbsp;• identifying, reviewing and evaluating candidates to serve on our board;

&nbsp;&nbsp;&nbsp;&nbsp;• determining the minimum qualifications for service on our board;

&nbsp;&nbsp;&nbsp;&nbsp;• developing and recommending to our board an annual self-evaluation process for our board and overseeing the annual self-evaluation process;

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.

#### Stockholder Communications with Board of Directors
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. 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.

------

#### **TABLE OF CONTENTS**
filed with the SEC during the fiscal year ended December 31, 2025 and Forms 5 and amendments thereto filed with the SEC with respect to such fiscal year, or written representations that no Forms 5 were required, we believe that there were no instances where our officers, directors and greater than ten percent beneficial owners failed to file on a timely basis all Section 16(a) filing requirements during the fiscal year ended December 31, 2025, other than the filing of a Form 4 on July 25, 2025, for each of Lars Boesgaard, Stephan Toutain,., and Kirk Shephard, each reporting one transaction and the filing of a Form 4 on July 25, 2025, for each of Frank Beddu-Addo, Ph.D, Spencer D. Brown and Gregory Conn, each reporting two transactions, which were filed late due to administrative oversights.

#### Narrative to Summary Compensation Table
*Key Performance Factors in Determining Executive Compensation* 

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:

&nbsp;&nbsp;&nbsp;&nbsp;• key R&D achievements

&nbsp;&nbsp;&nbsp;&nbsp;• initiation and progress of clinical trials for our product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;• achievement of regulatory milestones;

&nbsp;&nbsp;&nbsp;&nbsp;• new business initiatives including financings;

&nbsp;&nbsp;&nbsp;&nbsp;• our progress in building out key functions and managing our growth while maintaining a high-performing organization and culture; and

&nbsp;&nbsp;&nbsp;&nbsp;• increasing shareholder value.

#### **TABLE OF CONTENTS**
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 of our executive officers, for such year, 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.

*Elements of Executive Compensation* 

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 an amended and restated employment agreement with Dr. Bedu-Addo. We entered into employment agreements with Dr. Shepard and Mr. Toutain upon their commencement of employment in a substantially similar form as Dr. Bedu-Addo's employment agreement in order to provide consistency among our executive officers. The terms of the 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.

#### Base Salaries
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 $615,322 in 2025 and $597,000 in 2024. Dr. Shepard received a base salary of $463,500 in 2025 and $450,000 in 2024 (pro-rated for the 2024 calendar year based on his employment start date in 2024). Mr. Toutain received a base salary of $463,500 in 2025 and $450,000 in 2024 (pro-rated for the 2024 calendar year based on his employment start date in 2024).

#### Performance Bonuses
We offer our named executive officers the opportunity to earn discretionary 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 that is expressed as a percentage of his annual base salary. The 2025 target bonus amounts for each of Dr. Bedu-Addo, Dr. Shepard and Mr. Toutain were as follows:

---

| | |
|:---|:---|
| **Executive** | **2025 Target Bonus**  |
| Frank Bedu-Addo, Ph.D. | Up to 55% of Base Salary  |
| Kirk Shepard, M.D. | Up to 40% of Base Salary  |
| Stephan Toutain | Up to 40% of Base Salary |

---

------

#### **TABLE OF CONTENTS**
The Compensation Committee retains the discretion to reduce or eliminate any discretionary annual cash bonuses that might otherwise be payable, including in order to conserve cash for operations or capital expenditures supporting future growth in furtherance of our strategic priorities, or for other business opportunities that could either preserve or enhance stockholder value. Pursuant to this discretion, the Compensation Committee determined not to pay any discretionary annual cash bonuses to our named executive officers with respect to the 2025 performance year. The Compensation Committee's decision was not a reflection of the individual performance of any of our NEOs.

#### Equity Compensation
*<u>PDS Biotechnology Corporation 2014 Equity Incentive Plan</u>* 

In 2014, the Company's stockholders approved the 2014 Equity Incentive Plan (the "Original Plan") pursuant to which the Company was permitted to grant up to 91,367 shares subject to awards of incentive stock options ("ISOs"), non-qualified stock options and restricted stock units, subject to increases as hereafter described (the "Plan Limit"). In addition, on January 1, 2015, and each January 1 thereafter and prior to the termination of the 2014 Equity Incentive Plan, pursuant to the terms of the Original Plan, the Plan Limit was increased by the lesser of (x) 4% of the number of shares of Common Stock outstanding as of the immediately preceding December 31 and (y) such lesser number as the Board of Directors determined in its discretion.

In March 2019, the Board adopted and the Company's stockholders approved the Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the "Prior Plan") which amended and restated the Original Plan in order to remove the annual increase component and which fixed the number of shares of Common Stock authorized for issuance under the Prior Plan to 826,292 shares.

On December 8, 2020, the Board adopted and on June 17, 2021, the stockholders approved, the Second Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the "Restated Plan"), which amended and restated the Prior Plan. The Restated Plan was identical to the Prior Plan in all material respects, except (a) the number of shares of Common Stock authorized for issuance under the Restated Plan was increased from 826,292 shares to 4,165,535 shares, plus the total number of shares that remained available for issuance, that were not covered by outstanding awards issued under the Prior Plan, immediately prior to December 8, 2020; and (b) the Prior Plan was amended to terminate on December 7, 2030, unless earlier terminated.

On May 19, 2023, the Board adopted and on July 14, 2023, the stockholders approved, the Third Amended and Restated PDS Biotechnology Corporation 2014 Equity Incentive Plan (the "Third Restated Plan"), which amended and restated the Restated Plan to increase the total number of shares authorized for issuance thereunder from 4,165,535 shares to 6,565,535 shares.

On April 28, 2025, the Board adopted and on June 11, 2025, the stockholders approved, an amendment to the Third Restated Plan, which amendment increased the total amount of shares authorized for issuance under the Third Restated Plan to the sum of (i) 4,165,535 shares of Common Stock, which was the total number of shares of common stock authorized for issuance under the Restated Plan, plus (ii) 2,400,000 shares of common stock, which reflects the additional shares of common stock authorized by the Board under the Third Restated Plan as of its effective date, plus (iii) 3,144,049 shares of common stock that were approved at the Company's 2025 Annual Meeting of Stockholders. As of December 31, 2025, there were 3,741,247 shares available for grant under the Third Restated Plan, as amended.

*<u>2018 Stock Incentive Plan</u>* 

In 2018, the Company's stockholders approved the 2018 Stock Incentive Plan pursuant to which the Company may grant up to 558,071 shares subject to awards of (i) stock options, (ii) stock appreciation rights, (iii) restricted stock, (iv) deferred stock, (v) stock reload options and/or (vi) other stock-based awards. As of December 31, 2025, there were 190,799 shares of this pre-merger legacy plan left un-issued.

*<u>2019 Inducement Plan</u>* 

On June 17, 2019, the Board adopted the 2019 Inducement Plan (the "Inducement Plan") pursuant to which the Company may grant awards of non-qualified stock options. On December 8, 2020, the Company 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 Company further amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the

------

#### **TABLE OF CONTENTS**
Inducement Plan from 500,000 shares to 1,100,000 shares. On January 22, 2024, the Company further amended the Inducement Plan solely to increase the total number of shares of Common Stock reserved for issuance under the Inducement Plan from 1,100,000 shares to 2,100,000 shares. The Inducement Plan, and each amendment thereto, 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.

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 of the Company or member of the Board of Directors of the Company (or any 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, 2025, there were 1,087,407 shares available for grant under the Inducement Plan.

*<u>Stock Options</u>* 

Pursuant to the terms of the Third Restated Plan (as amended) and the 2018 Stock Incentive Plan, ISOs granted pursuant to such plans 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 period. 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.

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 granted pursuant to the Third Restated Plan (as amended) and the 2018 Stock Incentive Plan may be intended to qualify as incentive stock options under the Internal Revenue Code.

In accordance with Item 402(x) of Regulation S-K, we are providing information regarding our procedures related to the grant of stock options close in time to the release of material non-public information. Neither our Board nor our Compensation Committee takes material non-public information into account when determining the timing of equity awards, nor do we time the disclosure of material non-public information for the purpose of impacting the value of executive compensation. We generally issue equity awards to our executive officers on a limited and infrequent basis, and not in accordance with any fixed schedule.

The following table presents information required by Item 402(x)(2) of Regulation S-K regarding stock options issued to our named executive officers in fiscal year 2025 during the period beginning four business days before and ending one business day after the filing of a current report on Form 8-K that disclosed material non-public information:

#### **TABLE OF CONTENTS**
We sponsor a 401(k) defined contribution plan in which our named executive officers 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.

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.

If PDS Biotech terminates Dr. Bedu-Addo's employment without Cause, he resigns for Good Reason (each as defined in the employment agreement), 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 held by Dr. Bedu-Addo 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 in the employment agreement) (the "Protection Period"), instead of the bonus referenced in clause (ii) above, Dr. Bedu-Addo will receive a bonus equal to his target annual performance-based cash bonus.

With respect to each of Dr. Shepard and Mr. Toutain, if PDS Biotech terminates the executive's employment without Cause or the executive resigns for Good Reason (each as defined in the applicable executive's employment agreement), 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, in addition to the base salary and benefits continuation, the executive will also receive a payment equal to his target bonus, and any outstanding equity as of the closing of a Change in Control (as defined in the applicable executive's employment agreement) will become 100% vested if the executive's outstanding equity is assumed or continued by the surviving entity.

#### **TABLE OF CONTENTS**

#### Pay Versus Performance Disclosure
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, 2024, 2023 and 2022.

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.

&nbsp;&nbsp;&nbsp;&nbsp;(1) For each year shown, the principal executive officer ("PEO") was Dr. Bedu-Addo, our Chief Executive Officer. For 2025 and 2024, the other Named Executive Officers ("NEOs") were Dr. Shepard and Mr. Toutain. For 2023, the other Named Executive Officers ("NEOs") were Dr. Wood, Mr. Hill and Dr. Conn.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The values reflected in this column reflect the "Total" compensation set forth in the Summary Compensation Table ("SCT") above. See the footnotes to the SCT for further detail regarding the amounts in this column.

&nbsp;&nbsp;&nbsp;&nbsp;(3) "Compensation Actually Paid" is defined by the SEC and is computed in accordance with SEC rules by subtracting the amounts in the "Option Awards" column of the SCT for each year from the "Total" column of the SCT and then: (i) adding the fair value as of the end of the reported year of all awards granted during the reporting year that are outstanding and unvested as of the end of the reporting year; (ii) adding the amount equal to the change as of the end of the reporting year (from the end of the prior year) in fair value (whether positive or negative) of any awards granted in any prior year that are outstanding and unvested as of the end of the reporting year; (iii) adding, for awards that are granted and vest in the reporting year, the fair value as of the vesting date; (iv) adding the amount equal to the change as of the vesting date (from the end of the prior fiscal year) in fair value (whether positive or negative) of any awards granted in any prior year for which all applicable vesting conditions were satisfied at the end of or during the reporting year; (v) subtracting, for any awards granted in any prior year that are forfeited during the reporting year, the amount equal to the fair value at the end of the prior year; and (vi) adding the value of any dividends (or dividend equivalents) paid in the reporting year on unvested equity awards and the value of accrued dividends (or dividend equivalents) paid on performance awards that vested in the reporting year. The valuation assumptions used to calculate fair values did not materially differ from those disclosed at the time of grant.

&nbsp;&nbsp;&nbsp;&nbsp;(4) The cumulative total shareholder return ("TSR") is based on a fixed $100 investment made on December 31, 2022.

#### Item 402(x) of Regulation S-K
We are providing information regarding our procedures related to the grant of stock options close in time to the release of material non-public information. It is our policy that neither our Board nor our compensation committee takes material non-public information into account when determining the timing of equity awards, nor do we time the disclosure of material non-public information for the purpose of impacting the value of executive compensation. During fiscal 2025, there were no stock option or stock appreciation right awards granted to any named executive officers within four business days preceding, or one business day after, the filing of any report on Forms 10-K, 10-Q, or 8-K that disclosed material nonpublic information.

#### Director Compensation
*Director Compensation Policy* 

In June 2019, we adopted a director compensation policy. The director compensation policy was amended in April 2025, as described below, following a review of the program by our Compensation Committee. Pursuant to the policy, the annual cash retainer for non-employee directors is $40,000 and the annual cash retainer for the chair of the Board is $70,000. Annual retainers for committee membership are as follows:

---

| | |
|:---|:---|
| **Committee** | **Annual**<br>**Retainer**  |
| Audit Committee Chairperson | $18500  |
| Audit Committee Member | $8000  |
| Compensation Committee Chairperson | $15000  |
| Compensation Committee Member | $7500  |
| Nominating and Corporate Governance Committee Chairperson | $8000  |
| Nominating and Corporate Governance Committee Member | $4000 |

---

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, 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 and any committee of the board of directors on which they serve and in connection with other business related to the Board. 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 may determine that additional committee fees are appropriate and should be payable for any newly created committee of the Board.

In addition, pursuant to the changes made to our director compensation policy in April 2025, starting with fiscal year 2025, we grant new non-employee directors upon their initial election to the Board, an option to purchase 22,700 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 subject to an award upon a change in control of the Company.

Further, pursuant to the changes made to our director compensation policy in April 2025, on the dates of each of our annual meetings of stockholders, each non-employee director that has served on our Board for at least six months automatically receives an option to purchase 22,700 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 for less than six months shall receive an option for a pro rata number of shares. Each of these options has a term of 10 years from the date of the award and 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.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The amounts shown in this column do not reflect actual compensation received by our directors. The amounts reflect the grant date fair value of option awards and are calculated in accordance with the provisions of FASB Accounting Standards Codification Topic 718 Compensation - Stock Compensation and assume no forfeiture rate derived in the calculation of the grant date fair value of these awards. Assumptions used in calculating the value of these awards are included in Note 8, "Stock-Based Compensation" in the notes to the Company's financial statements included in our most recent Annual Report on Form 10-K. The director will only realize compensation to the extent the trading price of PDS Biotech's common stock is greater than the exercise price of such stock options at the time such options are exercised.

We may take further actions, in compliance with all appropriate government regulations, that we determine to be in the best interest of our employees.** 

**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.

#### CERTAIN RELATIONSHIPS AND RELATED-PARTY TRANSACTIONS
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, 2024 or any currently proposed transactions, to which PDS has been a participant, in which:

&nbsp;&nbsp;&nbsp;&nbsp;• the amounts exceeded or will exceed the lesser of $120,000 and 1% of the average of PDS Biotech's total assets at year-end for the fiscal years ended December 31, 2025 and 2024; and

&nbsp;&nbsp;&nbsp;&nbsp;• any of the directors, executive officers or holders of more than 5% of the respective capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

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.

#### PROPOSAL 2

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
**APPROVAL OF AN AMENDMENT TO OUR EIGHTH AMENDED AND RESTATED CERTIFICATE OF INCORPORATION, AS AMENDED, TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF OUR COMMON STOCK** 

Our Eighth Amended and Restated Certificate of Incorporation, as amended (the "Charter"), currently authorizes us to issue a total of 150,000,000 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 155,000,000 shares of all classes. On June 1, 2026, the Board approved an amendment to the Charter (the "Authorized Shares Amendment") to increase the number of shares of authorized common stock from 150,000,000 shares to 300,000,000 shares, subject to stockholder approval.

To be approved, this Proposal 2 must receive "For" votes from the majority of votes cast at the Annual Meeting proxy and that are entitled to vote on the matter. Abstentions are not counted as "votes cast" and will have no effect on the 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.

#### Reasons for the Authorized Shares Amendment
As of the Record Date, 55,815,653 shares of common stock were issued and outstanding and 2,130,309 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.

#### Potential Effects of Not Approving the Authorized Shares Amendment
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.

------

#### **TABLE OF CONTENTS**

#### Potential Effects of Approving the Authorized Shares Amendment
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.

#### Effectiveness of the Authorized Shares Amendment
The form of the Certificate of Amendment to the Charter to effect the Authorized Shares Amendment is attached as Appendix A to this proxy statement. If this Proposal 2 is approved by our stockholders, the Certificate of Amendment will become effective upon the acceptance by the Secretary of State of the State of Delaware of the filing of the Certificate of 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 150,000,000. Other than as described herein, this proposed Authorized Shares Amendment affects no other changes to our Charter.

#### RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED

#### PUBLIC ACCOUNTING FIRM
The Audit Committee has selected KPMG LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 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.

#### Principal Accountant Fees and Services
The following table represents aggregate fees billed to PDS Biotech for the fiscal years ended December 31, 2025 and 2024, 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, 2025 and 2024 were pre-approved by the Audit Committee or its properly delegated authority.

#### Pre-Approval Policies and Procedures
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.

#### &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

#### ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS
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 2027 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 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. Although non-binding, our Board and compensation committee will carefully review and consider the voting results when evaluating our executive compensation program.

#### THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS

#### A VOTE "FOR" THE APPROVAL, ON A NON-BINDING, ADVISORY BASIS, OF THE

#### HOUSEHOLDING OF PROXY MATERIALS
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.
