CHAIR’S LETTER

August 10, 2021

Dear Stockholder:

On behalf of the Board of Directors, it is our pleasure to invite you to the 2021 Annual Meeting of Stockholders of Soligenix, Inc. to be held on Thursday, September 23, 2021, at 9:00 a.m., Eastern Daylight Time. We are sensitive to the public health and travel concerns our stockholders, directors, employees and service providers may have and recommendations that public health officials have issued and may issue in light of the continuing public health crisis caused by COVID-19 even as more people are becoming vaccinated. After careful consideration, we have decided to hold a virtual only stockholder meeting. We feel this decision is in the best interests for our stockholders’ health in light of the latest information and advice regarding the spread of COVID-19.

We appreciate your investment and continued support of our company. This continues to be a very rewarding year for us. With the support of key patient advocacy organizations, such as the Cutaneous Lymphoma Foundation, and key opinion leaders, we continue to moving towards marketing approval and commercialization of HyBryte™ (SGX301 or synthetic hypericin). Under our Public Health Solutions business segment, we continue to advance our work with University of Hawaiʻi at Mānoa on filovirus vaccines (protecting against viruses such as Ebola and Marburg) and the development of vaccines to potentially combat coronaviruses, including SARS-CoV-2, the cause of COVID-19. We celebrate these successes and look forward to more opportunity ahead as we remain committed to the long-term interests of stockholders.

This year’s director nominees represent a wide range of backgrounds and expertise. We believe our diversity of experiences, perspectives, and skills contributes to the Board of Directors’ effectiveness in managing risk and providing guidance that positions the Company for long-term success. Of our five directors, four are independent, which includes all committee members.

This Proxy Statement contains details of the business to be conducted during the Annual Meeting and describes our corporate governance policies and practices. In addition to communicating information and our perspectives, we also believe in the value of listening to our stockholders. Feedback from our stockholders helps us prioritize our efforts and enhance our transparency.

Whether or not you participate in the Annual Meeting, it is important that your shares be represented and voted during the meeting. We urge you to promptly vote and submit your proxy (1) via the Internet (2) by telephone or (3) if you received your proxy materials by mail, by signing, dating, and returning the enclosed proxy card or voting instruction form in the envelope provided for your convenience.

As we look to the year ahead, we remain excited about the opportunities we have in terms of our business, stockholder value creation, and positive impacts on a global scale. Thank you for the trust you place in us and the opportunity to serve you and our company as directors. On behalf of all directors, I extend our gratitude for your support and request that you vote in the affirmative for the proposals to be considered at the Annual Meeting.


	Sincerely,


	Christopher J. Schaber, PhD
	Chairman of the Board of Directors,
	President and Chief Executive Officer

Voting Securities; Voting Your Shares; Proxies; Required Vote

Voting Securities

Each holder of record of our common stock, par value $0.001 per share (“Common Stock”), at the close of business on July 29, 2021 will be entitled to one vote for each share of Common Stock owned on that date as to each matter presented at the Annual Meeting. On July 29, 2021, 40,103,760 shares of Common Stock were outstanding.

Voting Your Shares

The Annual Meeting will be held entirely online. Stockholders may participate in the Annual Meeting by visiting the following website: www.virtualshareholdermeeting.com/sngx2021. To participate in the Annual Meeting, you will need the 16-digit control number included on your Notice of Internet Availability, on your proxy card or on the instructions that accompanied your proxy materials. Shares held in your name as the stockholder of record may be voted electronically during the Annual Meeting. Shares for which you are the beneficial owner but not the stockholder of record also may be voted electronically during the Annual Meeting. However, even if you to participate in the Annual Meeting, we recommend that you vote your shares in advance, so that your vote will be counted if you later decide not to attend the Annual Meeting. You may vote your shares via the Internet, telephone or mail as more fully described below:

●

By Internet: Go to www.proxyvote.com and follow the instructions (have your proxy card available);

●

By Telephone: Call 1-800-690-6903 and follow the voice prompts (have your proxy card available); and

●

By Mail: If you have received a proxy card, mark your vote, sign your name exactly as it appears on your proxy card, date your card and return it in the envelope provided.

Proxies

You cannot vote your shares at the meeting unless you vote electronically or are represented by proxy. All properly executed and unrevoked proxies that are received in time for the meeting will be voted at the meeting or any adjournment or postponement thereof in accordance with instructions thereon, or if no instructions are given, will be voted as follows:

“FOR ALL” in the election of all of the named nominees as directors;

“FOR” the approval, on an advisory basis, of the compensation of our executive officers;

“FOR” the ratification of EisnerAmper LLP as our independent registered public accounting firm for the year ending December 31, 2021; and

In accordance with the judgment of the persons appointed as proxies with respect to other matters which properly come before the Annual Meeting.

Stockholders of record may revoke their proxy at any time before the electronic polls close by submitting a later-dated vote online during the Annual Meeting, via the Internet, by telephone, or by mail, or by delivering written instructions to our Corporate Secretary before the Annual Meeting commences. Beneficial stockholders may revoke any prior voting instructions by contacting the broker, bank, or other nominee that holds their shares or by voting online during the meeting.

Required Vote

The affirmative vote of the holders of a plurality of the shares of Common Stock represented at the Annual Meeting in person or by proxy is required for each nominee to be elected as a director in the election of directors.

The affirmative vote of the holders of a majority of the shares of Common Stock represented in person or by proxy at the meeting is required to approve, on an advisory basis, the compensation of our executive officers.

The affirmative vote of the holders of a majority of the shares of Common Stock represented in person or by proxy at the meeting is required for the ratification of the appointment of EisnerAmper LLP as the independent registered public accounting firm for the fiscal year ending December 31, 2021.

Proposal 1 (the election of five directors to serve until the next Annual Meeting of Stockholders or until their respective successors have been duly elected and qualified); and Proposal 2 (the advisory vote on executive compensation) are considered “non-routine” matters. Proposal 3 (the ratification of the appointment of EisnerAmper LLP as our independent registered public accounting firm for the year ending December 31, 2021) is considered a “routine” matter. Banks, brokers, or other nominees (“Brokers”) who hold shares on behalf of beneficial stockholders have discretion to vote such shares with respect to “routine” matters without receiving voting instructions from the beneficial holders of the shares. However, Brokers who hold shares on behalf of beneficial stockholders do not have discretion to vote such shares with respect to “non-routine” matters if they do not receive voting instructions from the beneficial holders of the shares. If no instruction is given to Brokers with respect to “non-routine” matters, a “broker non-vote” is recorded for each such uninstructed share.

Stockholders are not allowed to cumulate their votes in the election of directors. In voting on the election of directors, abstentions and broker non-votes will be disregarded and not treated as votes cast and, therefore, will not affect the outcome of the election. Abstentions will have the same effect as votes against the proposals (1) regarding the advisory vote on executive compensation; and (2) to ratify the appointment of EisnerAmper LLP, but broker non-votes will not be counted as votes against such proposals or as shares present or represented at the meeting for these proposals.

Quorum

The required quorum for the transaction of business at the Annual Meeting is a majority of the voting power of shares of Common Stock issued and outstanding on the record date. Shares represented in person or by proxy (including shares which abstain or do not vote with respect to one or more of the matters presented for stockholder approval) will be counted for purposes of determining whether a quorum exists at the meeting.

Board Leadership Structure

Our Board of Directors believes that Dr. Schaber’s service as both the Chairman of our Board of Directors and our Chief Executive Officer is in the best interest of our Company and our stockholders. Dr. Schaber possesses detailed and in-depth knowledge of the issues, opportunities and challenges facing our Company and our business and, therefore, is best positioned to develop agendas that ensure that the Board of Directors’ time and attention are focused on the most important matters. His combined role enables decisive leadership, ensures clear accountability, and enhances our ability to communicate our message and strategy clearly and consistently to our stockholders, employees, and collaborative partners.

Mr. Lapointe, Ms. Parks, Dr. Rubin, and Dr. Zeldis, each of whom is nominated for election as a director, are independent and the Board of Directors believes that the independent directors provide effective oversight of management. Moreover, in addition to feedback provided during the course of meetings of the Board of Directors, the independent directors hold executive sessions. Following an executive session of independent directors, the independent directors’ report back to the full Board of Directors regarding any specific feedback or issues, provide the Chairman with input regarding agenda items for Board of Directors and Committee meetings, and coordinate with the Chairman regarding information to be provided to the independent directors in performing their duties. The Board of Directors believes that this approach appropriately and effectively complements the combined Chairman/Chief Executive Officer structure.

Although we believe that the combination of the Chairman and Chief Executive Officer roles is appropriate under the current circumstances, our corporate governance guidelines do not establish this approach as a policy, and the Board of Directors may determine that it is more appropriate to separate the roles in the future.

Director Independence

The Board of Directors has determined that Mr. Lapointe, Ms. Parks, Dr. Rubin, and Dr. Zeldis, each of whom is nominated for election as a director, are “independent” as such term is defined by the applicable listing standards of The NASDAQ Stock Market LLC (“Nasdaq”). Our Board of Directors based this determination primarily on a review of the responses of the Directors to questionnaires regarding their employment, affiliations and family and other relationships.

Corporate Governance

Pursuant to our Certificate of Incorporation and Bylaws, our business and affairs are managed under the direction of the Board of Directors. Members of the Board of Directors are kept informed of our business through discussions with senior

management, by reviewing materials provided to them and by participating in meetings of the Board of Directors and its committees.

The Board of Directors held four meetings in 2020, and each current director who served as a director during 2020, attended at least 75% of the aggregate number of meetings of the Board of Directors held during 2020 and of all committees of the Board of Directors on which he or she served during 2020.

We typically schedule a meeting of the Board of Directors in conjunction with our Annual Meeting and expect that all directors will attend, absent a valid reason, such as a scheduled conflict. Last year, all of the individuals then serving as directors attended the 2020 Annual Meeting.

Code of Ethics

We have adopted a code of ethics that applies to all of our executive officers and senior financial officers (including our chief executive officer, chief financial officer, chief accounting officer and any person performing similar functions). A copy of our code of ethics is publicly available on our website at www.soligenix.com under the “Investors – Corporate Governance” section. If we make any substantive amendments to our code of ethics or grant any waiver, including any implicit waiver, from a provision of the code to our chief executive officer, chief financial officer or chief accounting officer, we will disclose the nature of such amendment or waiver in a Current Report on Form 8-K.

Committees of the Board of Directors

Our Board of Directors has the following three committees: (1) Compensation, (2) Audit and (3) Nominating and Corporate Governance. Our Board of Directors has adopted a written charter for each of these committees, which are available on our website at www.soligenix.com under the “Investors – Corporate Governance” section.

Our Board of Directors has determined that Mr. Lapointe, Ms. Parks and Dr. Rubin, each of whom is nominated for election as a director, are “independent” directors, within the meaning of applicable listing standards of Nasdaq and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations thereunder. Our Board of Directors has also determined that the members of the Audit Committee are qualified to serve on the committee and have the experience and knowledge to perform the duties required of the committee and that Mr. Lapointe qualifies as an “audit committee financial expert” as that term is defined in the applicable rules and regulations of the Exchange Act and Nasdaq. The Audit Committee met five times during the fiscal year ended December 31, 2020.

Our Board of Directors has determined that Dr. Zeldis, Mr. Lapointe and Ms. Parks, each of whom is nominated for election as a director, are “independent” directors, as such term is defined by the applicable Nasdaq listing standards. The Nominating Committee met one time during the fiscal year ended December 31, 2020.

In considering candidates for the Board of Directors, the Nominating Committee considers the entirety of each candidate’s credentials and does not have any specific minimum qualifications that must be met by a nominee. However, the Nominating Committee believes that all members of the Board of Directors should have the highest character and integrity, a reputation for working constructively with others, sufficient time to devote to Board of Directors matters, and no conflict of interest that would interfere with performance as a director. In the case of current directors being considered for nomination, the Nominating Committee also takes into account the director’s history of attendance at meetings of the Board of Directors or its committees, the director’s tenure as a member of the Board of Directors, and the director’s preparation for and participation in such meetings.

Stockholders who wish to suggest qualified candidates should write to the Office of the Secretary, Soligenix, Inc., 29 Emmons Drive, Suite B-10, Princeton, New Jersey 08540, specifying the name of the candidates and stating in detail the qualifications of such persons for consideration by the Nominating Committee. A written statement from the candidate consenting to be named as a candidate and, if nominated and elected, to serve as a director should accompany any such recommendation. Stockholders who wish to nominate a candidate for election at an Annual Meeting of Stockholders must otherwise comply with our Bylaws regarding stockholder proposals and nominations. See “Deadline for Stockholder Proposals” contained herein.

Diversity Considerations in Identifying Director Nominees

We do not have a formal diversity policy or set of guidelines in selecting and appointing directors that comprise our Board of Directors. However, when making recommendations to our Board of Directors regarding the size and composition of our Board of Directors, our Nominating Committee does consider each individual director’s qualifications, skills, business experience and capacity to serve as a director and the diversity of these attributes for the Board of Directors as a whole.

Report of the Audit Committee of the Board of Directors ⁽¹⁾

The Audit Committee submits the following report for the year ended December 31, 2020:

The Audit Committee has reviewed and discussed with both management and the independent registered public accounting firm the audited consolidated financial statements as of and for the year ended December 31, 2020. The Audit Committee’s review included discussion with the auditors of the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board.

The Audit Committee has received the written disclosures and the letter from the independent auditors required by Public Company Accounting Oversight Board Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, and has discussed with the independent auditors matters relating to the auditors’ independence.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements referred to above be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 for filing with the United States Securities and Exchange Commission (the “SEC”).


	Submitted by the Audit Committee,

	/s/ Gregg A. Lapointe (Chair of Audit Committee)
	/s/ Diane L. Parks
	/s/ Robert J. Rubin

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Risk Oversight

The Board of Directors has an active role, as a whole and also at the committee level, in overseeing management of our risks. The Board of Directors regularly reviews information regarding our strategy, finances and operations, as well as the risks associated with each. The Audit Committee is responsible for oversight of our risks relating to accounting matters, financial reporting, internal controls and legal and regulatory compliance. The Audit Committee undertakes, at least annually, a review to evaluate these risks. The members then meet with management responsible for such area, including our Chief Financial Officer, and report to the Audit Committee on any matters identified during such discussions with management. In addition, the Compensation Committee considers risks related to the attraction and retention of talent as well as risks relating to the design of compensation programs and arrangements. In addition, the Nominating Committee manages risks associated with the independence of the Board of Directors. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board of Directors is regularly informed through committee reports about such risks. The full Board of Directors considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their respective areas of responsibility.

Recommendation of the Board of Directors

The Board of Directors recommends that you vote “FOR ALL” in the election of directors.

PROPOSAL 2

ADVISORY VOTE ON EXECUTIVE COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) requires companies that are subject to the SEC’s proxy rules and regulations to hold a stockholder vote to approve, on an advisory (non-binding) basis, the compensation of their named executive officers as disclosed in their proxy statements in accordance with the SEC’s rules.

As described under the heading “Executive Compensation,” our executive compensation programs are designed to attract, motivate, and retain our executive officers, who are critical to our success. Under these programs, our executive officers are rewarded for the achievement of annual, long-term and strategic goals, and corporate goals. Please read the “Executive Compensation” section beginning on page 21 for additional details about our executive compensation programs, including information about the fiscal year 2020 compensation of our Chief Executive Officer and each of the three other most highly compensated executive officers during 2020 who were serving as executive officers at the end of such year (collectively, the “Named Executive Officers”).

The Compensation Committee continually reviews the compensation programs for our Named Executive Officers to ensure they achieve the desired goals of aligning our executive compensation structure with our stockholders’ interests and current market practices. The Compensation Committee believes the Company’s executive compensation programs have been effective at incentivizing the achievement of financial performance and returns to stockholders.

We are asking our stockholders to indicate their support for our Named Executive Officers’ compensation as described in this Proxy Statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our Named Executive Officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our Named Executive Officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we will ask our stockholders to vote “FOR” the following resolution at the 2021 Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the Named Executive Officers, as disclosed in the Company’s Proxy Statement for the 2021 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the 2020 Summary Compensation Table and the other related tables and disclosure.”

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee or our Board of Directors. Our Board of Directors and our Compensation Committee value the opinions of our stockholders and to the extent there is any significant vote against the Named Executive Officers’ compensation as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns. In addition to the advisory vote on executive compensation, we are committed to ongoing engagement with our stockholders on executive compensation and corporate governance issues.

At the 2020 Annual Meeting of Stockholders, approximately 80% of the votes cast on the advisory vote on the executive compensation proposal were cast in favor of our Named Executive Officers’ compensation as disclosed in the proxy statement for last year’s meeting. Our Board of Directors and the Compensation Committee reviewed these final vote results and determined that, given the level of support, our Company should maintain the components of our compensation program.

We have determined that our stockholders should vote on a say-on-pay proposal each year, consistent with the preference expressed by our stockholders at the 2019 Annual Meeting of Stockholders.

Recommendation of the Board of Directors

The Board of Directors recommends that you vote “FOR” the executive compensation as described in this Proxy Statement.

PROPOSAL 3

RATIFICATION OF INDEPENDENT AUDITORS

The Audit Committee of the Board of Directors has appointed EisnerAmper LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021 to audit our financial statements for the year ending December 31, 2021 and to render other professional services as required, at the remuneration to be determined by the Audit Committee of the Board of Directors. A representative of EisnerAmper LLP is expected to be available at the Annual Meeting, will have the opportunity to make a statement if he or she desires to do so, and will be available to respond to appropriate questions.

We are asking our stockholders to ratify the selection of EisnerAmper LLP as our independent registered public accounting firm. Although ratification is not required by our Certificate of Incorporation, Bylaws or otherwise, the Board of Directors is submitting the selection of EisnerAmper LLP to our stockholders for ratification because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate practice. If the appointment is not ratified, the Audit Committee will consider whether it is appropriate to select another registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in our best interests and those of our stockholders.

The affirmative vote of the holders of a majority of the shares of Common Stock voted at the Annual Meeting is necessary to ratify the selection of EisnerAmper LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2021.

Pre-Approval Policies and Procedures

The Audit Committee has adopted a policy that requires advance approval of all audit services and permitted non-audit services to be provided by the independent auditor as required by the Exchange Act. The Audit Committee must approve the permitted service before the independent auditor is engaged to perform it. The Audit Committee approved all of the services described above in accordance with its pre-approval policies and procedures. The Audit Committee gives due consideration to the potential effect of non-audit services on maintaining the auditors’ independence.

Recommendation of the Board of Directors

The Board of Directors recommends that you vote “FOR” ratification of EisnerAmper LLP as our independent registered public accounting firm for the year ending December 31, 2021.

Executive Compensation Review

In 2018, in furtherance of our compensation philosophy and objectives, the Compensation Committee engaged Setren Smallberg & Associates (“SS&A”), an outside executive compensation consulting firm determined to be independent by the Compensation Committee, to conduct a review of, and recommend changes to, our compensation program for our executive officers. A representative of SS&A attended Compensation Committee meetings at the invitation of the Compensation Committee Chairman and was also in direct contact with the Compensation Committee and our management from time to time. SS&A provided the Compensation Committee with assistance and advice in the review of our salary structure, annual and equity incentive awards and other related executive pay issues. In addition, SS&A provided advice regarding marketplace trends and best practices relating to competitive pay levels.

SS&A did not provide any services to us other than its services as the Compensation Committee’s independent compensation consultant, and SS&A did not receive any fees or compensation from us other than the fee it received as the independent compensation consultant. SS&A did not provide any services to us in 2019 or 2020. The Compensation Committee confirmed that SS&A’s work for the Compensation Committee did not create any conflicts of interest.

Employment and Severance Agreements

Christopher J. Schaber, PhD

In August 2006, we entered into a three-year employment agreement with Christopher J. Schaber, PhD, and entered into a new three-year employment agreement with Dr. Schaber in December 2007. Pursuant to both the August 2006 employment agreement and the December 2007 employment agreement, we agreed to pay Dr. Schaber a base salary of $300,000 per year and a minimum annual bonus of $100,000. Dr. Schaber’s employment agreement automatically renews every three years, unless otherwise terminated, and was automatically renewed most recently in December 2019 for an additional term of three years. Pursuant to the August 2006 employment agreement, we issued him options to purchase 12,500 shares of our Common Stock, with one third immediately vesting and the remainder vesting over three years. No additional options were granted under the 2007 agreement. Upon termination without “Just Cause” as defined by this agreement, we would pay Dr. Schaber nine months of severance, as well as any accrued bonuses, accrued vacation, and we would provide health insurance and life insurance benefits for Dr. Schaber and his dependents. No unvested options shall vest beyond the termination date. . Upon a change in control of the company due to merger or acquisition, all of Dr. Schaber’s options shall become fully vested, and be exercisable for a period of five years after such change in control (unless they would have expired sooner pursuant to their terms). In the event of his death during the term of the agreement, all of his unvested options shall immediately vest and remain exercisable for the remainder of their term and become the property of Dr. Schaber’s immediate family.

In January 2020, our Board of Directors authorized an amendment to Dr. Schaber’s employment agreement to increase the number of shares of Common Stock from 5,000 to 500,000, issuable to Dr. Schaber immediately prior to the completion of a transaction or series or a combination of related transactions negotiated by our Board of Directors whereby, directly or indirectly, a majority of our capital stock or a majority of our assets are transferred from us and/or our stockholders to a third party.

In December 2020, our Board of Directors authorized an amendment to Dr. Schaber’s employment agreement to modify the severance terms. Upon termination without “Just Cause” as defined by this agreement, we would pay Dr. Schaber twelve months of severance, as well as a pro rata bonus calculated by the average of his prior two year’s annual bonuses, if any, and based on the number of months that he was employed during the year in which his employment was terminated; however, in the case of termination without “Just Cause” within one year following a change in control or the sale or other disposition of all or substantially all of our assets Dr. Schaber will be entitled 18 months of severance and health insurance and life insurance benefits for him and his dependents.

On June 22, 2011, the Compensation Committee eliminated his fixed minimum annual bonus payable and revised it to an annual targeted bonus of 40% of his annual base salary.

(1)

Directors who are compensated as full-time employees receive no additional compensation for service on our Board of Directors. Each independent director who is not a full-time employee is paid $35,000 annually, on a prorated basis, for their service on our Board of Directors, the chairman of our Audit Committee is paid $15,000 annually, on a prorated basis, and the chairmen of our Compensation and Nominating Committees is paid $10,000 annually, on a prorated basis. Additionally, Audit Committee members are paid $7,500 annually and Compensation and Nominating Committee members are paid $5,000 annually. This compensation is paid quarterly.

(2)

We maintain a stock option grant program pursuant to the nonqualified stock option plan, whereby members of our Board of Directors or its committees who are not full-time employees receive an initial grant of fully vested options to purchase 1,500 shares of Common Stock. Upon re-election to the Board, each Board member will receive stock options with a value of $30,000, calculated using the closing price of the Common Stock on the trading day prior to the date of the annual meeting of our stockholders, which vest at the rate of 25% per quarter, commencing with the first quarter after each annual meeting of stockholders.

(3)	Mr. Pearson resigned, for personal reasons, as a member of our Board of Directors, as well as all committees thereof, on March 31, 2020.

Consideration and Determination of Executive and Director Compensation

The Compensation Committee of the Board of Directors is comprised of Dr. Rubin (Chair), Mr. Lapointe, and Dr. Zeldis. The Board of Directors has determined that Dr. Rubin, Mr. Lapointe, and Dr. Zeldis are “independent” directors within the meaning of applicable listing standards of Nasdaq and the Exchange Act and the rules and regulations thereunder.

The Compensation Committee provides overall guidance on compensation and benefits policy. In addition, the Compensation Committee approves and monitors:

●

executive compensation and benefits programs;

●

executive employment agreements; and

●

our equity incentive plans.

The primary objectives of the Compensation Committee are to ensure that our executive compensation and benefits programs:

●

are competitive with other growing companies of similar size and business;

●

are effective in driving performance to achieve financial goals and create stockholder value;

●

are cost-efficient and fair to employees, management and stockholders; and

●

are designed to attract, motivate, reward, and retain the competent and talented executives needed.

To achieve these objectives, the Compensation Committee meets at least once and usually several times during each fiscal year to review the existing compensation and benefits programs and to consider modifications that seek to provide a direct relationship between executive compensation and sustained corporate performance.

The Compensation Committee makes executive compensation decisions on the basis of total remuneration and seeks to create an integrated total remuneration program structured to balance short and long-term financial goals. A significant amount of total compensation is comprised of bonus provisions which are specified in employment contracts and which are intended to align executive interest with stockholder interest.

The Compensation Committee recommends to the Board of Directors a salary within a designated range for the respective executives, which is based on merit, performance and length of service. Bonus provisions for all executives are based on increase (if any) of net incremental profit over prior year highest net profit.

Non-executive employees are granted stock options from time to time under our equity incentive plans, approved by the stockholders, also in order to motivate, reward, and retain them while meeting goals and allowing them to share in the growth.

Stock Ownership Policy

In April 2012, our Board of Directors adopted a stock ownership policy applicable to our non-employee directors to strengthen the link between director and stockholder interests. Pursuant to the stock ownership policy, each non-employee director is required to hold a minimum ownership position in the Common Stock equal to the annual cash compensation paid for service on the Board of Directors, exclusive of cash compensation paid for service as a chair or member of any committees of the Board of Directors.

Stock counted toward the ownership requirement includes Common Stock held by the director, unvested and vested restricted stock, and all shares of Common Stock beneficially owned by the director held in a trust and by a spouse and/or minor children of the director. The policy provides that the ownership requirement must be attained within three years after the later of June 21, 2012 and the date a director is first elected or appointed to the Board of Directors. To monitor progress toward meeting the requirement, the Nominating Committee will review director ownership levels at the end of March of each year. Non-employee directors are prohibited from selling any shares of Common Stock unless such director is in compliance with the stock ownership policy. A copy of our director compensation and stock ownership policy is publicly available on our website at www.soligenix.com under the “Investors – Corporate Governance” section.

Compensation Committee Interlocks and Insider Participation in Compensation Decisions

No member of our Compensation Committee is or has at any time during the past year been one of our officers or employees. None of our executive officers currently serves or in the past year has served as a member of the Board of Directors or Compensation Committee of any entity that has one or more executive officers serving on our Board of Directors or Compensation Committee.

Transactions with Related Persons

The Audit Committee is responsible for the review, approval and ratification of related party transactions. The Audit Committee reviews these transactions under our Code of Ethics, which governs conflicts of interests, among other matters, and is applicable to our employees, officers and directors.

We are party to a registration rights agreement with certain stockholders, including ACT Capital Management, LLLP and Altamont Pharmaceutical Holdings, LLC, each of which at one point since January 1, 2020 beneficially owned 5% or more of the shares of our outstanding Common Stock but which beneficially owns less than 5% of our outstanding

Common Stock as of July 29, 2021. The agreement provides that the stockholders have the right to require that we register its shares under the Securities Act of 1933, as amended (the “Securities Act”) for sale to the public, subject to certain conditions. The stockholders also have piggyback registration rights, which means that, if not already registered, they have the right to include their shares in any registration that we effect under the Securities Act, subject to specified exceptions. We must pay all expenses incurred in connection with the exercise of these demand registration rights.

We are unable to estimate the dollar value of the registration rights to the holders of these rights. The amount of reimbursable expenses under the agreements depends on a number of variables, including whether registration rights are exercised incident to a primary offering by us, the form on which we are eligible to register such a transaction, and whether we have a shelf registration in place at the time of a future offering.

Other than as described above, the employment agreements and compensation paid to our directors, we did not engage in any transactions with related parties since January 1, 2020. For a discussion of our employment agreements and compensation paid to our directors, see “Executive Compensation — Employment and Severance Agreements” and “Executive Compensation — Compensation of Directors.”

Deadline for Stockholder Proposals

Under SEC Rule 14a-8, stockholder proposals for the Annual Meeting of Stockholders to be held in 2022 will not be included in the proxy statement for that meeting unless the proposal is proper for inclusion in the proxy statement and for consideration at the next Annual Meeting of Stockholders, and is received by our Secretary at our executive offices, no later than April 12, 2022. Stockholders must also follow the other procedures prescribed in SEC Rule 14a-8 under the Exchange Act, as well as our Bylaws, which contain requirements that are separate and apart from the SEC requirements of Rule 14a-8. Our Bylaws provide that stockholders desiring to bring business before the 2022 Annual Meeting, including nomination of a person for election to our Board of Directors, must provide written notice to our Secretary at our executive offices no earlier than 75 days, and no later than 45 days, before the one-year anniversary of the mailing of this Proxy Statement. The written notice must include the information required by Section 2.4 of the Bylaws: (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director, all information relating to such person as would be required to be disclosed in solicitations of proxies for the election of such nominee as a director pursuant to Regulation 14A under the Exchange Act, and such person’s written consent to serve as a director if elected; (b) as to any other business that the stockholder proposes to bring before the meeting, a brief description of such business, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (c) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on our books, and of such beneficial owner, (ii) the class and number of our shares that are owned beneficially and of record by such stockholder and such beneficial owner, and (iii) whether either such stockholder or such beneficial owner intends to deliver a proxy statement and form of proxy to holders of, in the case of a proposal, at least the percentage of our voting shares required under applicable law to carry the proposal or, in the case of a nomination or nominations, a sufficient number of holders of our voting shares to elect such nominee or nominees.

Householding of Annual Meeting Materials

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements, annual reports and Notices of Internet Availability of Proxy Materials. This means that only one copy of our proxy statement, annual report or Notices of Internet Availability of Proxy Materials may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of any of the documents to you if you notify our Secretary at our executive offices of your desire to receive additional copies. If you wish to receive separate copies of the annual report, proxy statement and Notice of Internet Availability of Proxy Materials in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker, or other nominee record holder, or you may contact us at our executive offices.

Financial Statements and Exhibits to Form 10-K

Our financial statements are contained in our Annual Report on Form 10-K for our fiscal year ended December 31, 2020 that was filed with the SEC on March 30, 2021, a copy of which is made available with this Proxy Statement. Such report and the financial statements contained therein are not to be considered as a part of this soliciting material.

The Form 10-K made available with this Proxy Statement does not include copies of the exhibits to that filing. We will furnish any such exhibit upon payment of a reasonable fee by request sent to us, c/o Office of the Secretary, Soligenix, Inc., 29 Emmons Drive, Suite B-10, Princeton, New Jersey 08540.

Other Matters

Management knows of no matters that are to be presented for action at the meeting other than those set forth above. If any other matters properly come before the meeting, the persons named in the form of proxy will vote the shares represented by proxies in accordance with their judgment on such matters.

The cost of this proxy solicitation will be borne by us. In addition to the solicitation of proxies by mail, our directors, officers and employees may also solicit proxies by telephone, facsimile, e-mail or other forms of communication, without special compensation for such activities. We may engage the services of a professional proxy solicitation firm to aid in the solicitation of proxies. If we do, our costs for such services will be within the range of what is customary for companies with similar operations and a similar number of stockholders and are not expected to be material. We will also request banks, brokers, fiduciaries, custodians, nominees and certain other record holders to send proxies, proxy statements and other materials to their principals at our expense. We will reimburse such banks, brokers, fiduciaries, custodians, nominees and other record holders for their reasonable out-of-pocket expenses of solicitation.
