How does the Board recommend that I vote?

The Board unanimously recommends a vote "FOR" the Director Nominees in Proposal 1, and a vote "FOR" each of Proposal 2, Proposal 3 and Proposal 4.

How do Proxies Work?

Our Board is asking for your proxy. This means that you authorize persons selected by us to vote your shares at the meeting in the way you instruct and, with regard to any other business that may properly come before the meeting, as they think best.

I Share an Address with Another Stockholder and We Received Only One Paper Copy of the Proxy Materials. How May I Obtain an Additional Copy of the Proxy Materials?

The Company has adopted a procedure called "householding," which the SEC has approved. Under this procedure, if requested to deliver proxy materials, we deliver a single copy of the Notice, the Proxy Statement and the Annual Report to multiple stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. This procedure reduces our printing and mailing costs, and the environmental impact of our annual meetings. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will promptly deliver a separate copy of the Notice, the Proxy Statement and the Annual Report to any stockholder at a shared address to which we delivered a single copy of any of these documents.

To receive a separate copy of the Notice, the Proxy Statement and the Annual Report, you may contact us at the following address and phone number:

Dominari Holdings Inc.

725 5th Avenue, 23rd Floor

New York, New York 10022

Attention: Corporate Secretary

Telephone: (212) 393-4540

Stockholders who hold shares in "street name" (as described below) may contact their brokerage firm, bank, broker-dealer or other similar organization to request information about householding.

Who is Entitled to Vote?

Our Board has fixed the close of business on October 20, 2026, as the "Record Date" for a determination of stockholders entitled to notice of, and to vote at, the 2026 Annual Meeting or any adjournment thereof. You can vote at the 2026 Annual Meeting if you held shares of our common stock, Series D convertible preferred stock (the "Series D Preferred Stock") or Series D-1 convertible preferred stock (the "Series D-1 Preferred Stock", collectively, the "Voting Capital") as of the close of business on the Record Date. On the Record Date, there were 25,201,979 shares of common stock outstanding, 3,825 shares of Series D Preferred Stock outstanding and 834 shares of Series D-1 Preferred Stock outstanding. Each share of common stock entitles the holder thereof to one vote.

Our outstanding Series D Preferred Stock and Series D-1 Preferred Stock are entitled to the following number of votes subject to the beneficial ownership limitations described below:

• Series D Preferred Stock - each share of Series D Preferred Stock entitles the holder to 0.007285 votes;

• Series D-1 Preferred Stock - each share of Series D-1 Preferred Stock entitles the holder to 0.007285 votes.

A list of stockholders of record entitled to vote at the 2026 Annual Meeting will be available for inspection at our principal executive offices located at 725 5th Avenue, 23rd Floor, New York, New York 10022 for a period of at least ten (10) days prior to the 2026 Annual Meeting and during the meeting. The stock transfer books will not be closed between the Record Date and the date of the 2026 Annual Meeting.

What is the Difference Between Holding Shares as a Record Holder and as a Beneficial Owner (Holding Shares in Street Name)?

If your shares are registered in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are the "record holder" of those shares. If you are a record holder, these proxy materials have been provided directly to you by the Company.

If your shares are held in a stock brokerage account, a bank or other holder of record, you are considered the "beneficial owner" of those shares held in "street name." If your shares are held in street name, these proxy materials have been forwarded to you by that organization. As the beneficial owner, you have the right to instruct this organization on how to vote your shares.

Who May Attend the 2026 Annual Meeting?

Record holders and beneficial owners on the Record Date may attend the 2026 Annual Meeting. If your shares are held in street name and you would like to vote your shares at the 2026 Annual Meeting, you will need to obtain a valid proxy from the broker, bank, trustee or nominee that holds your shares giving you the right to vote the shares at the 2026 Annual Meeting.

How Will My Shares Be Voted?

All shares which are entitled to vote and represented by a properly completed, executed and delivered proxy received before the 2026 Annual Meeting and not revoked will be voted at the 2026 Annual Meeting as instructed by you in a proxy delivered before the 2026 Annual Meeting. If you do not indicate how your shares should be voted on a matter, the shares represented by your proxy will be voted "for" the approval of each of the Director Nominees, "for" each of Proposal 2, Proposal 3 and Proposal 4, and with regard to any other matters that may be properly presented at the 2026 Annual Meeting and all matters incident to the conduct of the meeting. All votes will be tabulated by the inspector of elections appointed for the meeting, who will separately tabulate affirmative and negative votes, abstentions and broker non-votes.

Is My Vote Confidential?

Yes, your vote is confidential. The only persons who have access to your vote are the inspector of elections, individuals who help with processing and counting your votes, and persons who need access for legal reasons. Occasionally, stockholders provide written comments on their proxy cards, which may be forwarded to our Company's management and the Board.

What Constitutes a Quorum?

To carry on business at the 2026 Annual Meeting, we must have a quorum. A quorum is present when at least 33 1/3 of the shares entitled to vote as of the Record Date are represented in person or by proxy. Thus, holders of the Voting Capital representing at least 8,400,671 votes must be represented in person or by proxy at the 2026 Annual Meeting to have a quorum. Your shares will be counted towards the quorum only if you submit a valid proxy (or if one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the 2026 Annual Meeting.

Abstentions and broker non-votes will be counted towards the quorum requirement. Shares held by us in treasury are not considered outstanding or considered to be present at the 2026 Annual Meeting. If there is not a quorum at the 2026 Annual Meeting, our stockholders may adjourn the meeting.

What is a Broker Non-Vote?

If your shares are held in street name, you must instruct the organization who holds your shares how to vote your shares. If you do not provide voting instructions, your shares will not be voted on any non-routine proposal. This vote is called a "broker non-vote". If you sign your proxy card, but do not provide instructions on how your broker should vote, your broker will vote your shares as recommended by our Board. Broker non-votes are not included in the tabulation of the voting results of any of the proposals and, therefore, do not affect these proposals.

Proposal 2 (the ratification of the appointment of Grassi & Co., CPAs, P.C. as our independent registered public accounting firm) is a "routine" matter on which your broker can exercise voting discretion. All other proposals are considered non-routine and therefore brokers cannot use discretionary authority to vote shares on other proposals to be considered at the 2026 Annual Meeting if they have not received instructions from their clients. Please submit your proxy card so your vote is counted.

What is an Abstention?

An abstention is a stockholder's affirmative choice to decline to vote on a proposal. Abstentions are not included in the tabulation of the voting results for any of the proposals and, therefore, do not affect these proposals. Abstentions are included for the purpose of determining whether a quorum has been reached.

How Many Votes Are Needed for Each Proposal to Pass?

What Are the Voting Procedures?

In voting by proxy regarding the election of the Class III directors, you may vote in favor of the nominees or withhold your votes as to the nominees. Regarding other proposals, you may vote in favor of or against the proposal, or you may abstain from voting on the proposal. You should specify your respective choices on the accompanying proxy card.

All shares represented by proxy will be voted at the 2026 Annual Meeting in accordance with the choices specified on the proxy, and where no choice is specified, in accordance with the recommendations of the Board. Thus, where no choice is specified, the proxies will be voted FOR the Director Nominees in Proposal 1, and FOR each of Proposals 2, 3 and 4.

Is My Proxy Revocable?

You may revoke your proxy and reclaim your right to vote at any time before it is voted by (i) giving written notice to our administrator, (ii) delivering a properly completed, later-dated proxy card to us or (iii) voting via the Internet at the 2026 Annual Meeting. All written notices of revocation and other communications with respect to revocations

of proxies should be addressed to: Dominari Holdings Inc., 725 5th Avenue, 23rd Floor, New York, New York 10022, Attention: Chief Operating Officer. Revocations of proxies must be received prior to the time of the 2026 Annual Meeting to serve as an effective revocation of that proxy.

Do I Have Appraisal Rights?

Our stockholders do not have appraisal rights under Delaware law or under our governing documents with respect to the matters to be voted upon at the 2026 Annual Meeting.

How can I find out the Results of the Voting at the 2026 Annual Meeting?

Preliminary voting results will be announced at the 2026 Annual Meeting. Final voting results will be published in a Current Report on Form 8-K, which we will file with the SEC within four (4) business days after the meeting.

Board Leadership Structure and Role in Risk Oversight

Mr. Hayes currently holds the roles of Chairman of the Board and Chief Executive Officer ("CEO"). As Chairman of the Board and CEO, Mr. Hayes serves as the primary liaison between the Company and the independent directors. With input from other members of the Board, committee chairs and management, he presides over meetings of the Board.

Our Board, as a unified body and through committee participation, organizes the execution of its monitoring and oversight roles and does not expect its Chairman to organize those functions.

The Board has four standing committees: (i) Audit, (ii) Compensation, (iii) Nominating & Governance, and (iv) Investment. The Audit, Compensation, and Nominating & Governance committees are comprised of all independent directors, with each of the committees having a separate chairman, each of whom is an independent director. Our non-management members of the Board meet in executive session at each quarterly board meeting.

Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. Management is responsible for the day-to-day management of risks we face, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, the Board has the responsibility for ensuring that the risk management processes designed and implemented by management are adequate and functioning as designed.

The Board believes that establishing the right "tone at the top" and that full and open communication between executive management and the Board are essential for effective risk management and oversight. Our CEO and Chairman communicates frequently with other members of the Board to discuss strategy and the challenges we face. Senior management usually attends our regular quarterly Board meetings and is available to address any questions or concerns raised by the Board on risk management-related and any other matters.

Board Committees and Charters

The following table identifies the current independent and non-independent Board and Committee members:

Audit Committee

The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (the "Exchange Act") and is currently comprised of Mr. Brian Parsley and Mr. Kyle Haug (Chairman), each of whom the Board has determined satisfies the applicable SEC and Nasdaq independence requirements for audit committee members. The Audit Committee has authority to review our financial records, deal with our independent auditors, recommend financial reporting policies to the Board, and investigate all aspects of our business.

The Board has also determined that Mr. Haug is an "audit committee financial expert," as defined by the applicable rules of the SEC and Nasdaq.

The Nominating Committee currently consists of Mr. Gregory James Blattner (Chairman) and Brian Parsley each of whom the Board has determined satisfies the applicable SEC and Nasdaq independence requirements.

Among other factors, when considering a prospective candidate, the Nominating Committee considers a candidate's business experience and skills, attributes pertinent to Company business, personal integrity and judgment, and possible conflicts of interest. To date, the Nominating Committee has not utilized the services of any search firm to assist it in identifying director candidates. The Nominating Committee's policy is to consider director candidate recommendations from its stockholders which are received prior to any annual meeting of stockholders, including confirmation of the candidate's consent to serve as a director.

Stockholder Communication

As a stockholder of our Company, you may communicate in writing at any time with the entire Board or any individual director (addressed to "Board of Directors" or to a named director), c/o Dominari Holdings Inc., Attention: Chief Operating Officer, 725 5th Avenue, 23rd Floor, New York, New York 10022, or via e-mail at [email protected].

Meetings of the Board of Directors and Committees

Our Board held, during the year 2025, a total of 6 regularly scheduled and special meetings, the Audit Committee held 4 meetings, the Compensation Committee held 6 meetings, the Investment Committee and the Nominating Committee did not hold any meetings. Each of our incumbent directors attended at least 75% of the Board and Committee meetings.

Policy Regarding Attendance at Annual Meetings of Stockholders

Our Company does not have a policy regarding Board members' attendance at annual meetings of stockholders. All of our directors attended our last annual meeting of stockholders.

Director Qualifications and Diversity

The Board seeks independent directors who represent a diversity of backgrounds and experiences that will enhance the quality of the Board's deliberations and decisions. Candidates should have substantial experience with one or more publicly traded companies or should have achieved a high level of distinction in their chosen fields. The Board is particularly interested in maintaining a mix that includes individuals who are active or retired executive officers and senior executives, particularly those with experience in strategic planning, business development, compensation, finance, accounting and banking.

In evaluating nominations to the Board, the Nominating Committee also looks for certain personal attributes, such as integrity, ability and willingness to apply sound and independent business judgment, comprehensive understanding of a director's role in corporate governance, availability for meetings and consultation on Company matters, and the willingness to assume and carry out fiduciary responsibilities. The Nominating Committee took these specifications into account in formulating and re-nominating its present Board members.

Code of Ethics

We have adopted a Code of Ethics, which is available on our website at www.dominariholdings.com.

Conflicts of Interest

Members of our management are associated with other firms involved in a range of business activities. Consequently, there are potential inherent conflicts of interest in their acting as officers and directors of the Company. Although the officers and directors are engaged in other business activities, we anticipate they will devote an important amount of time to our affairs.

Our officers and directors are now and may in the future become stockholders, officers or directors of other companies, which may be formed for the purpose of engaging in business activities similar to ours. Accordingly, additional direct conflicts of interest may arise in the future with respect to such individuals acting on behalf of us or other entities. Moreover, additional conflicts of interest may arise with respect to opportunities which come to the attention of such individuals in the performance of their duties or otherwise. Currently, we do not have a right of first refusal pertaining to opportunities that come to their attention and may relate to our business operations.

Our officers and directors are, so long as they are our officers or directors, subject to the restriction that all opportunities contemplated by our plan of operation which come to their attention, either in the performance of their duties or in any other manner, will be considered opportunities of, and be made available to us and the companies that they are affiliated with on an equal basis. A breach of this requirement will be a breach of the fiduciary duties of the officer or director. If we or the companies with which the officers and directors are affiliated both desire to take advantage of an opportunity, then said officers and directors would abstain from negotiating and voting upon the opportunity. However, all directors may still individually take advantage of opportunities if we should decline to do so. Except as set forth above, we have not adopted any other conflict of interest policy with respect to such transactions.

Review, Approval or Ratification of Transactions with Related Persons

The Board reviews issues involving potential conflicts of interest, and reviews and approves all related party transactions, including those required to be disclosed as a "related party" transaction under applicable federal securities laws. The Board has not adopted any specific procedures for conducting reviews of potential conflicts of interest and considers each transaction in light of the specific facts and circumstances presented. However, to the extent a potential related party transaction is presented to the Board, the Company expects that the Board would become fully informed regarding the potential transaction and the interests of the related party and would have the opportunity to deliberate outside of the presence of the related party. The Company expects that the Board would only approve a related party transaction that was in the best interests of, and fair to, the Company, and further would seek to ensure that any completed related party transaction was on terms no less favorable to the Company than could be obtained in a transaction with an unaffiliated third party.

Compliance with Section 16(a) of the Exchange Act

Section 16(a) of the Exchange Act requires our Directors and named Executive Officers, and anyone who beneficially owns ten percent (10%) or more of our Company's Common Stock, to file with the SEC initial reports of beneficial ownership and reports of changes in beneficial ownership of Common Stock. Persons required to file such reports also need to provide us with copies of all Section 16(a) forms they file.

Based solely upon a review of (i) copies of the Section 16(a) filings received during or with respect to 2025, and (ii) certain written representations of our officers and directors, we believe that all filings required to be made pursuant to Section 16(a) of the Exchange Act during and with respect to 2025 were filed in a timely manner.

Narrative Disclosure to Summary of Compensation Table

Employment Agreements

Anthony Hayes

On June 28, 2021, we entered into an employment agreement with Anthony Hayes (the "Hayes Agreement"), pursuant to which Mr. Hayes serves as our Chief Executive Officer. Under an amendment effective April 1, 2023, the term of the Hayes Agreement is for five years from the effective date of the amendment with automatic one-year extensions unless either the Company or Mr. Hayes gives six months' non-renewal notice.

The annual bonus has two components, one is an annual revenue bonus that becomes payable upon the Company's achievement of certain annual revenue targets, as stated in the table below.

The second component is a net revenue bonus equal to 15% of the sum of (i) all fees and proceeds received by the Company's wholly-owned subsidiary, Dominari Securities LLC (the "IB"), in connection with investment banking services performed by the IB, including but not limited to the proceeds received from the exercise and sale of shares underlying any warrants or options issued in connection therewith, less the fees and expenses paid to individual representatives (i.e. broker payouts) of the IB out of such fees and/or proceeds ("Net Investment Banking Fees") and (ii) any revenue received by the Company or any of its subsidiaries, including but not limited to the IB, in connection with alternative business opportunities that occur from time to time, including but not limited to, profits (including proceeds from warrants and options) received on all carried interest on "Special Purpose Vehicles" or other investment vehicles that the Company or any of its subsidiaries, including but not limited to IB, may have a pecuniary interest in ("Alternate Revenue"). Alternate Revenue is broadly interpreted to capture any revenue not included in Net Investment Banking Fees that benefits the Company or any of its subsidiaries and is net of any fees or expenses paid to any employees of the Company or its subsidiaries, including the IB.

Our Board of Directors may adopt different or additional performance criteria for future years after consultation with Mr. Hayes, provided that such criteria must be reasonably attainable. The bonus, to the extent earned, will be paid on the date on which annual bonuses are paid generally to the Company's senior executives, provided that Mr. Hayes is employed with the Company on the payment date. In 2025, the payment of the bonuses was accelerated and paid upon the incremental certification by our Compensation Committee that the Company achieved the applicable revenue targets.

The Hayes Agreement also provides that Mr. Hayes will be entitled to participate in pension, profit sharing, group insurance, hospitalization, group health and benefit plans, perquisites, and all other benefits and plans the Company provides to its senior officers. If at any time during the term, the Company does not provide its senior executives with health insurance, Mr. Hayes will be entitled to secure such insurance for himself and his immediate family and the Company will reimburse him for the cost of such insurance.

The Hayes Agreement provides that upon Mr. Hayes' termination due to (A) his death, (B) disability, (C) by the Company without cause (as defined in the Hayes Agreement), or (D) due to the Company not renewing the Hayes Agreement term, he or his estate will be entitled to the following: (i) twelve months' base salary paid in a lump sum, (ii) continued group health coverage (if validly elected) for 12 months at the same cost as applied prior to his termination, and (iii) the pro-rata portion of any earned annual bonus.

If Mr. Hayes' employment is terminated (A) by Mr. Hayes for good reason (as defined in the Hayes Agreement) or (B) within 30 days of a change in control (as defined in the Hayes Agreement), then Mr. Hayes will be entitled to receive the following: (i) twelve months' base salary paid in a lump sum, (ii) continued group health coverage (if validly elected) for 12 months at the same cost as applied prior to his termination, (iii) the pro-rata portion of any earned annual bonus, and (iv) full vesting of all outstanding and then unvested equity awards.

On March 20, 2026, the Company entered into amendments to the employment agreements of Anthony Hayes.

Mr. Devall is also entitled to the payment or reimbursement of up to $10,000 per month for reasonable out-of-pocket expenses.

The employment agreement also provides for customary events of termination of employment and provides that in the event of termination as a result of Mr. Devall's death or disability, Mr. Devall is entitled to severance consisting of (i) twelve (12) months of his then current base salary, payable in a lump sum, less withholding of applicable taxes, within thirty (30) days of the date of termination; (ii) if he elects continuation coverage for group health coverage pursuant to COBRA, then for a period of twelve (12) months following the termination of Mr. Devall's employment the Company will pay such amount of the COBRA premiums so that Mr. Devall is only required to pay the portion of the premiums that active employees are required to pay; and (iii) payment on a pro-rated basis of any annual bonus or other payments earned in connection with any bonus plan to which Mr. Devall was a participant as of the date of death or disability. In the event of termination of Mr. Devall's employment (i) as a result of the non-renewal of the employment agreement by the Company at the end of the then current term, (ii) by Mr. Devall for "good reason" (as such term is defined in the employment agreement), (iii) by the Company, without cause, or (iv) by Mr. Devall, in the event of a change in control, then Mr. Devall is entitled to the same severance as provided above. Additionally, if termination is by Mr. Devall for good reason or by the Company, without cause, then all equity grants held by Mr. Devall will immediately vest.

Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Non-Public Information

The Company does not maintain a policy on the timing of awards of options in relation to the disclosure of material nonpublic information. Our Board and Compensation Committee did not take into account any material nonpublic information in determining the timing of the equity awards made to our NEOs in 2024, as such awards were made pursuant to their employment agreements and granted upon the attainment of specified performance goals. We did not time the disclosure of material nonpublic information for the purpose of affecting the value of our executive compensation in 2024.

Retirement Benefits

Our NEOs are eligible to participate in our 401(k) plan, which is a defined contribution plan offered to all of our full-time employees. There are no other retirement benefit arrangements covering our NEOs.

Termination and Change in Control Benefits

The material terms of the contracts with each of our NEOs are summarized above, including the payments to NEOs at, following, or in connection with the resignation, change in control, or other termination of an NEO.

In accordance with SEC rules, the "compensation actually paid" amounts shown in the table below for each applicable year reflect certain adjustments to the values reported in the Summary of Compensation Table as described in the footnotes to the following table. The Company previously reported an estimated "net loss" number in this table because the Company's audited financial statements were not complete as of the date of the Company's most recent proxy statement. The Company's audited financial statements are now complete and the "net loss" reported below is derived from such audited financial statements.

In accordance with the SEC rules for smaller reporting companies, only three years of information is provided.

Analysis of the Information Presented in the Pay versus Performance Table

The Company's executive compensation program reflects a variable pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance, all of those Company measures are not presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company's performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular year. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

Our Board has appointed Grassi & Co., CPAs, P.C. ("Grassi"), to serve as our independent registered public accounting firm for the year ending December 31, 2026. A representative of Grassi is expected to be present at the 2026 Annual Meeting.

On June 24, 2026, with the approval of the Audit Committee, the Company dismissed CBIZ CPAs P.C. ("CBIZ CPAs") as the Company's independent registered public accounting firm. As previously disclosed in a Current Report on Form 8-K filed on April 30, 2025, on April 25, 2025, Marcum LLP was dismissed, and CBIZ CPAs was appointed as the Company's independent registered public accounting firm for the fiscal year ended December 31, 2025. On June 24, 2026, the Company engaged Grassi & Co., CPAs, P.C. ("Grassi") to serve as its independent registered public accounting firm for the fiscal year ending December 31, 2026.

The reports of CBIZ regarding the Company's financial statements for the fiscal years ended December 31, 2025 and 2024, did not contain any adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

The selection of our independent registered public accounting firm is not required to be submitted to a vote of our stockholders for ratification. However, our Company is submitting this matter to the stockholders as a matter of good corporate governance. Even if the appointment is ratified, the Board may, in its discretion, appoint a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of our Company and our stockholders. If the appointment is not ratified, the Board will consider its options.

Our Audit Committee retains our independent registered public accounting firm and approves in advance all audit and non-audit services performed by this firm and any other auditing firms. Although management has the primary responsibility for the financial statements and the reporting process including the systems of internal control, the Audit Committee consults with management and our independent registered public accounting firm regarding the preparation of financial statements and generally oversees the relationship of the independent registered public accounting firm with our Company. The independent registered public accounting firm is responsible for expressing an opinion on the conformity of those audited financial statements with generally accepted accounting principles, relating to their judgments as to the quality, not just the acceptability, of the Company's accounting principles, and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards.

It is not the duty of the Audit Committee to determine that our Company's financial statements and disclosures are complete and accurate and in accordance with generally accepted accounting principles or to plan or conduct audits. Those are the responsibilities of management and the Company's independent registered public accounting firm. In giving its recommendation to the Board, the Audit Committee has relied on: (1) management's representation that such financial statements have been prepared with integrity and objectivity and in conformity with generally accepted accounting principles; and (2) the report of the Company's independent registered public accounting firm with respect to such financial statements.

No non-audit services were performed by our principal accountants during the fiscal years ended December 31, 2025 and 2024. Our Audit Committee pre-approves these services by category and service. Our Audit Committee has pre-approved all of the services provided by our principal accountants.

The SEC has adopted rules requiring public companies to provide stockholders with periodic advisory (non-binding) votes on executive compensation, also referred to as "say-on-pay" proposals. At our 2023 annual meeting of stockholders, our stockholders approved a proposal that we shall have an advisory vote on executive compensation every three years. Accordingly, we are presenting the following proposal, which gives you as a stockholder the opportunity to endorse or not endorse the compensation paid to our current Chief Executive Officer, President and Chief Operating Officer (collectively, the "Named Executive Officers"), as disclosed in the section entitled "Executive Compensation" of this Proxy Statement pursuant to Item 402 of Regulation S-K (including the compensation tables and accompanying narrative discussion).

Pursuant to the Exchange Act and the rules promulgated thereunder, this vote will not be binding on the Board or the Compensation Committee and may not be construed as overruling a decision by the Board or the Compensation Committee, creating or implying any change to the fiduciary duties of the Board or the Compensation Committee or any additional fiduciary duty by the Board or the Compensation Committee or restricting or limiting the ability of stockholders to make proposals for inclusion in proxy materials related to executive compensation. The Board and the Compensation Committee, however, may in their discretion take into account the outcome of the vote when considering future executive compensation arrangements.

VOTE REQUIRED

This matter will be decided by the affirmative vote of a majority of votes cast at the 2026 Annual Meeting. Both abstentions and broker non-votes will not have the effect of a vote against this proposal.

RECOMMENDATION OF THE BOARD

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF THE COMPANY'S NAMED EXECUTIVE OFFICERS AS DESCRIBED IN THIS PROXY STATEMENT.

PROPOSAL 4:
TO APPROVE AN AMENDMENT OF THE RIGHTS AGREEMENT, DATED AS OF OCTOBER 11, 2023, BY AND BETWEEN CONTINENTAL STOCK TRANSFER & TRUST COMPANY

Background

The stockholders are being asked to approve an amendment to the Rights Agreement, dated as of October 11, 2023, by and between Continental Stock Transfer & Trust Company (the "Rights Agreement") for the purpose of extending the rights granted to stockholders under Section 7(a) of the Rights Agreement through October 11, 2027 and further amending Section 7(a) of the Rights Agreement to permit two additional twelve (12) month extensions, through, October 11, 2029. Our Board previously approved the amendment to the Rights Agreement to permit an extension through October 11, 2027.

The Company entered into the Rights Agreement to preserve past net operating losses ("NOLs") so that they may be used against potential future federal income tax obligations. Section 382 of the Internal Revenue Code of 1986, as amended (the "Tax Code") limits a company's ability to use its NOLs against future federal income tax obligations if the Company experiences an "ownership change" within the meaning of the Code. Under the Code, a company generally experiences such an "ownership change" if the percentage of its stock owned by its "5-percent shareholders," as defined in the Tax Code, increases by more than 50 percentage points over a rolling three-year period. The Rights Agreement is designed to reduce the likelihood that the Company will experience an ownership change under the Tax Code by discouraging any person or group from becoming a shareholder of 4.99% or more of Common Stock and discouraging any existing 4.99% shareholder from acquiring any additional shares of the Company's stock. Accordingly, renewing the Rights Agreement is in the best interest of stockholders of the Company such that it limits the likelihood that the Company will experience an ownership change.

Description of the Rights Agreement

The Rights Agreement provides each stockholder of record a dividend distribution of one "right" for each outstanding share of common stock. Rights become exercisable at the earlier of ten days following: (1) a public announcement that an acquirer has purchased or has the right to acquire 4.99% or more of our common stock, in connection with, (x) the Company consolidating, or merging into any other person, (y) any person consolidates or merges with or into the Company or (z) the Company sells or otherwise transfers to any person or persons, in one or more transactions, assets or earning power aggregating 50% or more of the assets or earning power of the Company or (2) the commencement of a tender offer which would result in an offer or beneficially owning 10% or more of our outstanding common stock. All rights held by an acquirer or offer or expire on the announced acquisition date, and all rights expire at the earliest of: (i) the close of business on October 11, 2025, subject to extension; (ii) the time at which the Rights are redeemed; (iii) the time at which the rights are exchanged; (iv) the closing of any merger or other acquisition transaction involving the Company pursuant to a specified agreement; (vi) the close of business on the date the Board determines that the Rights Agreement is no longer necessary or desirable for the preservation of tax benefits; and (vii) the close of business on the first day of a taxable year of the Company to which the Board determines that no tax benefits are available to be carried forward. Each right entitles a stockholder to acquire, at a price of $5.00 per one one-thousandth of a share of our Series Q Preferred Stock, subject to adjustments, which carries voting and dividend rights similar to one share of our common stock. The purchase price of the preferred stock fractional amount is subject to adjustment for certain events as described in the Rights Agreement. At the discretion of a majority of the Board and within a specified time period, we may redeem all of the rights at a price of $0.0001 per right. The Board may also amend any provisions of the Rights Agreement prior to exercise.

Language of the Amendment

If Rights Agreement Proposal is approved by shareholders, Section 7(a) of the Rights Agreement shall be amended and replaced with the following:

"(a) Subject to Section 7(e) hereof, the registered holder of any Rights Certificate may exercise the Rights evidenced thereby (except as otherwise provided herein including, without limitation, in the restrictions on exercisability set forth in Sections 9(c), 11(a)(iii) and 23(a) hereof) in whole or in part at any time after the Distribution Date upon surrender of the Rights Certificate, with the form of election to purchase and the certificate

on the reverse side thereof properly completed and duly executed, to the Rights Agent at the office of the Rights Agent designated for such purpose, together with payment of the Exercise Price for each one one-thousandth of a share of Preferred Stock (or Common Stock, other securities, cash or other assets, as the case may be) as to which the Rights are exercised prior to the earliest of (i) the Close of Business on October 11, 2027, unless this Agreement is renewed up to two additional twelve (12) month periods through October 11, 2029, as may be approved by the Board prior to the expiration of the Rights as long as each such twelve (12) month renewal period is submitted to the stockholders of the Company for their approval and is thereby approved, and, if not approved, with respect to any such twelve (12) month renewal period, then the last date for which this Agreement is in effect (the "Final Expiration Date"); (ii) the time at which the Rights are redeemed pursuant to Section 23 hereof (the "Redemption Date"); (iii) the time at which the Rights are exchanged pursuant to Section 24 hereof (the "Exchange Date"); (iv) the closing of any merger or other acquisition transaction involving the Company pursuant to an agreement of the type described in Section 13(f) at which time the Rights are terminated; (the "Early Expiration Date"); (vi) the Close of Business on the effective date of the repeal of Section 382 of the Code if the Board determines that this Agreement is no longer necessary or desirable for the preservation of Tax Benefits; and (vii) the Close of Business on the first day of a taxable year of the Company to which the Board determines that no Tax Benefits are available to be carried forward (the earliest of (i) - (vii) being herein referred to as the "Expiration Date").

VOTE REQUIRED

The affirmative vote of the majority of shares of common stock present in person or represented by proxy at the Annual Meeting and entitled to vote is required to approve the Rights Agreement Proposal. Abstentions will have no effect on the outcome of the vote.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE RIGHTS AGREEMENT PROPOSAL.
