IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE STOCKHOLDER MEETING TO BE HELD ON TUESDAY, June 16, 2026

This Proxy Statement and our 2025 Annual Report to Stockholders are available at www.edocumentview.com/ZETA

Proposals

At the Annual Meeting, our stockholders will be asked:

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in their discretion.

Recommendations of the Board

The Board recommends that you vote your shares as indicated below. If you return a properly completed proxy card, or vote your shares by telephone or Internet, your shares of Common Stock will be voted on your behalf as you direct. If not otherwise specified, the shares of Common Stock represented by the proxies will be voted by the proxies in accordance with the recommendations of the Board, and the Board recommends that you vote:

Information About This Proxy Statement

Why you received this proxy statement. You are viewing or have received these proxy materials because the Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the U.S. Securities and Exchange Commission (“SEC”) and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, Zeta is making this proxy statement and its 2025 Annual Report available to its stockholders electronically via the Internet. On or about April 24, 2026, we will mail to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2025 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2025 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet or phone, or how to request a paper proxy card. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained in the Internet Notice.

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.
 

Householding. The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notice of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or single set of the proxy 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.

To take advantage of this opportunity, we have delivered only one copy of the Internet Notice and, if applicable, one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate set of proxy materials, as requested, to any stockholder at a shared address to which a single set of those documents was delivered. If you prefer to receive separate copies of the proxy materials, please submit your request by writing to: Zeta Global Holdings Corp., Attn: Secretary, 3 Park Ave, 33rd Floor, New York, NY 10016 or by calling our Secretary at (212) 967-5055.

This year, a number of brokers with account holders who are our stockholders will likely be “householding” our proxy materials. A single Notice of Internet Availability of Proxy Materials or single set of the proxy 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 Notice of Internet Availability of Proxy Materials or full set of proxy materials, please notify your broker. Stockholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials or the full set of proxy materials at their addresses and would like to request “householding” of their communications should contact their brokers.

QUESTIONS AND ANSWERS ABOUT THE 2026 Annual Meeting OF STOCKHOLDERS

Who is entitled to vote at the Annual Meeting?

The Record Date for the Annual Meeting is April 17, 2026. You will be entitled to vote at the Annual Meeting only if you were a holder of record of Class A Stock or Class B Stock at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each outstanding share of Class A Stock is entitled to one vote per share and each outstanding share of Class B Stock is entitled to 10 votes per share on all matters presented at the Annual Meeting. The holders of Class A Stock and Class B Stock will vote together as a single class on all matters presented to stockholders at the Annual Meeting. On the Record Date, there were 225,609,644 shares of Class A Stock and 23,638,426 shares of Class B Stock outstanding and entitled to vote at the Annual Meeting, representing 48.8% and 51.2% of the voting power of our Common Stock, respectively.

What is the difference between being a “record holder” and holding shares in “street name”?

A record holder holds shares in his or her name. Shares held in “street name” means shares that are held in the name of a bank or broker on a person’s behalf.

Am I entitled to vote if my shares are held in “street name”?

Yes. If your shares are held by a bank or a brokerage firm, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in street name, these proxy materials are being provided to you by your bank or brokerage firm, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank or brokerage firm how to vote your shares, and the bank or brokerage firm is required to vote your shares in accordance with your instructions. If your shares are held in street name, you may not vote your shares in person at the Annual Meeting, unless you obtain a legal proxy from your bank or brokerage firm.

How many shares must be present to hold the Annual Meeting?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting in person or by proxy, of the holders of a majority in voting power of the Common Stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum.

Who can attend the Annual Meeting?

You may attend the Annual Meeting only if you are a Zeta stockholder who is entitled to vote at the Annual Meeting, or if you hold a valid proxy for the Annual Meeting. If you plan to attend the Annual Meeting, you must email the Company’s investor relations staff at ir@zetaglobal.com no later than 5:00 p.m. Eastern time on June 9, 2026 to have your name placed on the attendance list. In order to be admitted into the Annual Meeting, your name must appear on the attendance list, and you must present government-issued photo identification (such as a driver’s license). If your bank or broker holds your shares in street name, you will also be required to present proof of beneficial ownership of our Common Stock on the Record Date, such as the Internet Notice you received from your bank or broker, a bank or brokerage statement, or a letter from your bank or broker showing that you owned shares of our Common Stock at the close of business on the Record Date.

What if a quorum is not present at the Annual Meeting?

If a quorum is not present at the scheduled time of the Annual Meeting, then either the Chairperson of the Annual Meeting or a majority in voting power of the stockholders entitled to vote at the meeting, present in person or by proxy, is authorized by our Amended and Restated Bylaws to recess or adjourn the meeting. At any recessed or adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.

What does it mean if I receive more than one Internet Notice or more than one set of proxy materials?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials,

please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

How do I vote?

Stockholders of Record. If you are a stockholder of record, you may vote:

Internet and telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern time, on June 15, 2026. To vote via the Internet or telephone, you will need the control number included on your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials.

Whether or not you expect to attend the Annual Meeting, we urge you to vote your shares as promptly as possible to ensure your representation and the presence of a quorum at the Annual Meeting. If you submit your proxy, you may still decide to attend the Annual Meeting and vote your shares.

Beneficial Owners of Shares Held in “Street Name.” If your shares are held in “street name” through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares in person at the Annual Meeting, you should contact your bank or broker to obtain a legal proxy and bring it to the Annual Meeting in order to vote.

Can I change my vote after I submit my proxy?

Yes.

If you are a stockholder of record, you may revoke your proxy and change your vote:

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you vote in person at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote in person at the Annual Meeting by obtaining a legal proxy from your bank or broker and submitting the legal proxy along with your ballot.

Who will count the votes?

A representative of Computershare, our inspector of election, will tabulate and certify the votes.

What if I do not specify how my shares are to be voted?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, as well as with the description of each proposal in this proxy statement.

Will any other business be conducted at the Annual Meeting?

We know of no other business that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting, however, the proxy holders named on the Company’s proxy card will vote your shares in their discretion.

Will there be a question and answer session during the Annual Meeting?

As part of the Annual Meeting, we will hold a Q&A session, during which we intend to answer questions that are pertinent to the Company and the meeting matters, as time permits. Only stockholders that attend the Annual Meeting will be permitted to ask questions during the Annual Meeting. Each stockholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things:

How many votes are required for the approval of the proposals to be voted upon, and how will withholds, abstentions and broker non-votes be treated?

What is a “vote withheld” and an “abstention,” and how will votes withheld and abstentions be treated?

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the two other proposals to be voted on at the Annual Meeting, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors and abstentions have no effect on the ratification of the appointment of Deloitte & Touche LLP or the approval, on an advisory (non-binding) basis, of the compensation of our named executive officers.

What are broker non-votes and do they count for determining a quorum?

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as the election of directors and the approval, on an advisory (non-binding) basis, of the compensation of our named executive officers. Broker non-votes count for purposes of determining whether a quorum is present.

Where can I find the voting results of the Annual Meeting?

We plan to announce preliminary voting results at the Annual Meeting, and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC within four business days of the date of the Annual Meeting.

PROPOSALS TO BE VOTED ON

Proposal 1: Election of Directors

At the Annual Meeting, three (3) Class II directors are to be elected to hold office until the Annual Meeting of Stockholders to be held in 2029 and until each such director’s respective successor is elected and qualified or until each such director’s earlier death, resignation or removal.

Our current Class II Directors are William Landman, Robert Niehaus and Jeanine Silberblatt. The Board has nominated each of our Class II incumbent directors to serve as Class II directors until the 2029 Annual Meeting. We currently have seven (7) directors on our Board.

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the three (3) nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

In accordance with our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws, our Board is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to the directors whose terms will then expire will be elected to serve from the time of election and qualification until the third annual meeting following their election. The current class structure is as follows: Class I, whose term will expire at the 2028 Annual Meeting of Stockholders; Class II, whose current term will expire at the Annual Meeting, and, if elected at the Annual Meeting, whose subsequent term will expire at the 2029 Annual Meeting of Stockholders; and Class III, whose term will expire at the 2027 Annual Meeting of Stockholders. The current Class I Directors are Jené Elzie and William Royan; the current Class II Directors are William Landman, Robert Niehaus and Jeanine Silberblatt; and the current Class III Directors are David Steinberg and Imran Khan.

Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that, subject to the rights of holders of any series of preferred stock, the authorized number of directors may be changed from time to time by the Board. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. Prior to the date as of which the holders of Class B Stock no longer hold at least a majority of the voting power of the outstanding shares of Common Stock (the “Sunset Date”), and subject to the rights of the holders of any series of preferred stock then outstanding in respect of preferred stock directors, any director or the entire Board may only be removed with or without cause by the affirmative vote of the holders of a majority in voting power of our Common Stock then entitled to vote at an election of directors. After the Sunset Date, any director or the entire Board may be removed only for cause and only by the affirmative vote of the holders of a majority in voting power of our Common Stock then entitled to vote at an election of directors.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of Common Stock represented by the proxy for the election as Class II directors the persons whose names and biographies appear below. All of the persons whose names and biographies appear below are currently serving as our directors. In the event that any of William Landman, Robert Niehaus and Jeanine Silberblatt should become unable to serve, or for good cause will not serve, as a director, it is intended that votes will be cast for a substitute nominee designated by the Board, or the Board may elect to reduce its size. The Board has no reason to believe that any of the director nominees will be unable to serve if elected. Each of the director nominees has consented to being named in this proxy statement and to serve if elected.

Vote Required

The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the three (3) nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II directors. Votes withheld and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

Recommendation of the Board of Directors

The Board unanimously recommends a vote FOR the election of each of the below Class II director nominees.

Nominees For Class II Director (terms to expire at the 2029 Annual Meeting)

The nominees for election to the Board as Class II Directors are as follows:

The principal occupations and business experience, for at least the past five years, of each Class II Director nominee for election at the Annual Meeting are as follows:

David Steinberg

David Steinberg has been a member of our Board since 2007 and is the Co-founder, Chairman and Chief Executive Officer of Zeta.

We believe Mr. Khan is qualified to serve on our Board due to his longstanding experience in investment and company management.

Proposal 2: Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Our Board has directed that this appointment be submitted to our stockholders for ratification at the Annual Meeting. Although ratification of our appointment of Deloitte & Touche LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Deloitte & Touche LLP also served as our independent registered public accounting firm for the fiscal year ended December 31, 2025. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit services. A representative of Deloitte & Touche LLP is expected to attend the Annual Meeting and to have an opportunity to make a statement if he or she desires to do so, and be available to respond to appropriate questions from stockholders.

In the event that the appointment of Deloitte & Touche LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2027. Even if the appointment of Deloitte & Touche LLP is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interest of the Company.

Vote Required

This proposal requires the affirmative vote of the holders of a majority in voting power of the votes cast. Abstentions are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal. Because brokers have discretionary authority to vote on the ratification of the appointment of Deloitte & Touche LLP, we do not expect any broker non-votes in connection with this proposal.

Recommendation of the Board of Directors

The Board unanimously recommends a vote FOR the ratification of the appointment of Deloitte & Touche LLP as our Independent Registered Public Accounting Firm for the fiscal year ending December 31, 2026.

Proposal 3: Approval, on an Advisory (Non-Binding) Basis, of the Compensation of Our Named Executive Officers

In accordance with the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and Rule 14a-21 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company requests that our stockholders cast a non-binding, advisory vote to approve the compensation of our named executive officers identified in the section titled “Compensation Discussion and Analysis” in this proxy statement, including the compensation tables and the accompanying narrative disclosure contained therein, in accordance with the SEC’s compensation disclosure rules. 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 ask our stockholders to vote FOR the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders approve, on a non-binding advisory vote, the compensation of the named executive officers, as disclosed in the Company’s Proxy Statement for the 2026 Annual Meeting of Stockholders, pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation tables and narrative discussion.”

We believe that our compensation programs and policies for the year ended December 31, 2025 were an effective incentive for the achievement of our goals, aligned with stockholders’ interest and were worthy of stockholder support. Additional details concerning how we structure our compensation programs to meet the objectives of our compensation program are provided in the section titled “Compensation Discussion and Analysis” set forth below in this proxy statement.

This say-on-pay vote is advisory, and therefore will not be binding on the Company, our Board or the Compensation Committee. However, the Board and the Compensation Committee value the opinions of our stockholders and intend to take into account the outcome of the vote when considering future executive compensation decisions. The Board values constructive dialogue on executive compensation and other significant governance topics with our stockholders and encourages all stockholders to vote their shares on this important matter.

Unless otherwise determined by our Board, the next say-on-pay vote will be held at our 2027 annual meeting of stockholders.

Vote Required

The approval, on an advisory (non-binding) basis, of the compensation of our named executive officers will require the affirmative vote of the holders of a majority in voting power of the votes cast at the Annual Meeting. Abstentions and broker non-votes are not considered to be votes cast and, accordingly, will have no effect on the outcome of the vote on this proposal.

Recommendation of the Board of Directors

The Board unanimously recommends a vote FOR the approval, on an advisory (non-binding) basis, of the compensation of our named executive officers.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The audit committee reviews the Company’s financial reporting process on behalf of the Board. Management has the primary responsibility for the financial statements, the reporting process and maintaining an effective system of internal control over financial reporting. The Company’s independent auditors are engaged to audit and express opinions on the conformity of the Company’s financial statements to United States generally accepted accounting principles.

In addition to fulfilling its oversight responsibilities as set forth in its charter and further described in the section titled “Committees of the Board,” the audit committee has done the following things:

Based on the reviews and discussions with management and Deloitte cited above, including the review of Deloitte’s disclosures and letter to the audit committee and review of the representations of management and the reports of Deloitte, the audit committee recommended to the Board that the Company’s audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 filed with the SEC.

The foregoing report shall not be deemed incorporated by reference by any general statement incorporating by reference this Proxy Statement into any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Securities Exchange Act of 1934, as amended (the “Exchange Act”), except to the extent that the Company specifically incorporates this information by reference, and shall not otherwise be deemed filed under the Securities Act or the Exchange Act.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS

The following table summarizes the fees of Deloitte & Touche LLP, our independent registered public accounting firm, billed to us for each of the last two fiscal years for audit services and billed to us in each of the last two fiscal years for other services:

Audit Fees

Audit fees for the fiscal years ended December 31, 2025 and December 31, 2024 include fees for professional services rendered for the audit of our annual consolidated financial statements and for reviews of our financial statements included in our Quarterly Reports on Form 10-Q.

Audit Committee Pre-Approval Policy and Procedures

The Audit Committee has adopted a policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage Deloitte & Touche LLP to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by Deloitte & Touche LLP has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the Audit Committee or by a designated member of the Audit Committee to whom the committee has delegated the authority to grant pre-approvals. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. The Audit Committee may, on a periodic basis, review and generally pre-approve the services (and related fee levels or budgeted amounts) that may be provided by Deloitte & Touche LLP without first obtaining specific pre-approval from the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations. The Audit Committee pre‑approved all services performed since the Pre‑Approval Policy was adopted.

CORPORATE GOVERNANCE

General

Our Board has adopted Corporate Governance Guidelines, a Code of Ethics and Conduct, and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of the Company. You can access our current committee charters, our Corporate Governance Guidelines, and our Code of Ethics and Conduct in the “Governance” section of the “Investors” page of our website located at www.investors.zetaglobal.com, or the Company will furnish a copy of such documents to any person, without charge, upon written request to our Secretary at our offices at 3 Park Ave, 33rd Floor, New York, NY 10016. The information on or accessed through our website is deemed not to be incorporated in or part of this proxy statement or any other document filed with or furnished to the SEC.

Board Composition

Our Board currently consists of seven members: David Steinberg, Jené Elzie, Imran Khan, William Landman, Robert Niehaus, William Royan and Jeanine Silberblatt. Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that the authorized number of directors may be changed only by resolution of the Board. Prior to the Sunset Date, directors may be removed with or without cause only by the affirmative vote of the holders of a majority in voting power of our Common Stock then entitled to vote at an election of directors. After the Sunset Date, directors may be removed only for cause by the affirmative vote of the holders of a majority in voting power of our Common Stock then entitled to vote at an election of directors.

Director Independence

Our Board has determined that each of Jené Elzie, Imran Khan, William Landman, Robert Niehaus, William Royan and Jeanine Silberblatt qualifies as “independent” in accordance with the listing requirements of the New York Stock Exchange (“NYSE”). In making these determinations, our Board reviewed and discussed information provided by the directors and management with regard to each director’s business and personal activities and relationships as they may relate to the Company and our management. John Sculley also qualified as “independent” in accordance with the listing requirements of the NYSE during the period of time he served on the Board during 2025. There are no family relationships among any of our directors or executive officers.

Executive Sessions

Our non-management directors meet in executive session without management directors or other members of management present on a regularly scheduled basis. We also hold an executive session including only independent directors at least once per year. Robert H. Niehaus currently serves as our Lead Independent Director and presides over executive sessions.

Director Candidates

The Nominating and Corporate Governance Committee is primarily responsible for searching for qualified director candidates for election to the Board and filling vacancies on the Board. To facilitate the search process, the Nominating and Corporate Governance Committee may solicit current directors and executives of the Company for the names of potentially qualified candidates or ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from the Company and potential conflicts of interest and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee for candidates for election as a director.

In evaluating the suitability of individual candidates (both new candidates and current Board members), the Nominating and Corporate Governance Committee, in recommending candidates for election, and the Board, in approving (and, in the case of vacancies, appointing) such candidates, may take into account many factors, including:

personal and professional integrity, strong ethics and values; experience in corporate management, such as serving as an officer or former officer of a publicly held company; experience as a board member or executive officer of another publicly held company; professional and academic experience relevant to the Company’s industry; leadership skills; experience in finance and accounting and/or executive compensation practices; whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable; and how the candidate contributes to the range of backgrounds, experience, and perspectives on the board. The Nominating and Corporate Governance Committee and the Board aim to identify a broad pool of qualified candidates, drawing from the broadest feasible range of backgrounds, to consider when determining new Board candidates. The Board evaluates each individual in the context of the Board as a whole, with the objective of assembling a group that can best perpetuate the success of the Company’s business. In addition, the Board will consider whether there are potential conflicts of interest with the candidate’s other personal and professional pursuits.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, Zeta Global Holdings Corp., 3 Park Ave, 33rd Floor, New York, NY 10016. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

Communications from Stockholders and other Interested Parties

The Board will give appropriate attention to written communications that are submitted by stockholders and other interested parties, and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and other interested parties and for providing copies or summaries to the directors as he considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary and Chairperson of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders and other interested parties who wish to send communications on any topic to the Chairperson of the Board, the independent or non-management directors, or the Board as a whole, should address such communications to the applicable party or parties in writing: c/o Secretary, Zeta Global Holdings Corp., 3 Park Ave, 33rd Floor, New York, NY 10016.

Board Leadership Structure and Role in Risk Oversight

Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board with flexibility to combine or separate the positions of Chairperson of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. The Company’s current Board leadership structure comprises a combined Chairperson of the Board and Chief Executive Officer as well as highly qualified, active independent directors. Our Board exercises its judgment in combining or separating the roles of Chairperson of the Board and Chief Executive Officer as it deems appropriate in light of prevailing circumstances. The Board will continue to exercise its judgment on an ongoing basis to determine the optimal Board leadership structure that the Board believes will provide effective leadership, oversight and direction, while optimizing the functioning of both the Board and management and facilitating effective communication between the two. The Board has concluded that the current structure provides a well-functioning and effective balance between strong Company leadership and appropriate safeguards and oversight by independent directors.

Risk assessment and oversight are an integral part of our governance and management processes. Our Board encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board at regular

Board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks.

Our Board is responsible for overseeing our risk management process. Our Board focuses on our general risk management strategy, the most significant risks facing us, and oversees the implementation of risk mitigation strategies by management and for overseeing management of regulatory risks. Our Audit Committee is responsible for discussing our policies with respect to risk assessment and risk management, including guidelines and policies to govern the process by which our exposure to risk is handled, and for overseeing financial and cybersecurity risks. Our Nominating and Corporate Governance Committee manages risks associated with the independence of our Board and potential conflicts of interest. Our Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure.

Code of Ethics and Conduct

We have a written Code of Ethics and Conduct that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and agents and representatives. We have posted a current copy of the Code of Ethics and Conduct on our website, www.investors.zetaglobal.com, in the “Governance” section under “Governance Documents.” The nominating and corporate governance committee of our Board is responsible for overseeing our Code of Ethics and Conduct and any waivers applicable to any director, executive officer or employee. We intend to disclose any future amendments to certain provisions of our Code of Ethics and Conduct, or waivers of such provisions applicable to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and agents and representatives, on our website identified above or in public filings within four business days. In addition, we intend to post on our website all disclosures that are required by law or the rules of the NYSE concerning any amendments to, or waivers from, any provision of the Code of Ethics and Conduct.

Insider Trading Compliance Policy / Anti-Hedging Policy

The Company has adopted an Insider Trading Compliance Policy that governs the purchase, sale, and/or other dispositions of our securities by directors, officers and employees that is reasonably designed to promote compliance with insider trading laws, rules and regulations, and the listing requirements of the NYSE. A copy of our Insider Trading Compliance Policy is available as Exhibit 19.1 to our 2025 Annual Report. Further, the policy prohibits our directors, officers and employees and any entities they control from purchasing financial instruments such as prepaid variable forward contracts, equity swaps, collars, and exchange funds, or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities.

Compensation Committee Interlocks and Insider Participation

During 2025, William Landman, Robert Niehaus and Jené Elzie served on our Compensation Committee. Except as described below in the section titled “Certain Relationships and Related Person Transactions,” none of the members of our Compensation Committee is or has been an officer or employee of the Company, and none had or have any relationships with the Company during the last completed fiscal year that are required to be disclosed under Item 404 of Regulation S-K under the Exchange Act. None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee (or other board of directors committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of any entity that has one or more executive officers serving on our Board or Compensation Committee.

Attendance by Members of the Board of Directors at Meetings

There were seven meetings of the Board during the fiscal year ended December 31, 2025, and each director attended at least 75% of the aggregate of (i) all meetings of the Board and (ii) all meetings of the committees on which the director served during the period in which he or she served as a director.

Under our Corporate Governance Guidelines, which are available on our website at www.investors.zetaglobal.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities.

Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), with the understanding that, on occasion, a director may be unable to attend a meeting. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chairperson of the Board or the Chair of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, it is expected that absent compelling circumstances directors will attend. All seven of our directors attended the annual meeting of stockholders in 2025.

COMMITTEES OF THE BOARD

Our Board has established three standing committees—Audit, Compensation and Nominating and Corporate Governance—each of which operates under a written charter that has been approved by our Board.

The members of each of the Board committees and committee Chairpersons are set forth in the following chart.

Audit Committee

Our audit committee oversees our accounting and financial reporting process. Among other matters, the audit committee:

The Audit Committee charter is available on our website at www.investors.zetaglobal.com. Our audit committee consists of Robert Niehaus, William Royan and Imran Khan. Our Board has determined that all members are independent under the NYSE listing rules and Rule 10A-3(b)(1) of the Exchange Act. The chair of our audit

committee is Robert Niehaus. Our Board has determined that each member is an “audit committee financial expert” as such term is currently defined in Item 407(d)(5) of Regulation S-K. Our Board has also determined that each member of our audit committee can read and understand fundamental consolidated financial statements, in accordance with applicable requirements.

The Audit Committee met four times in 2025.

Compensation Committee

Our Compensation Committee is responsible for assisting the Board in the discharge of its responsibilities relating to the compensation of our executive officers. In fulfilling its purpose, our Compensation Committee has the following principal duties:

The Compensation Committee generally considers the Chief Executive Officer’s recommendations when making decisions regarding the compensation of non-employee directors and executive officers (other than the Chief Executive Officer). Pursuant to the Compensation Committee’s charter, which is available on our website at www.investors.zetaglobal.com, the Compensation Committee has the authority to retain or obtain the advice of compensation consultants, legal counsel and other advisors to assist in carrying out its responsibilities.

The Compensation Committee may delegate its authority under its charter to one or more subcommittees as it deems appropriate from time to time. The Compensation Committee may also delegate to an executive officer the authority to grant equity awards to certain employees and consultants, as further described in its charter and subject to the terms of our equity plans.

Our Compensation Committee consists of William Landman, Robert Niehaus and Jené Elzie. The chair of our compensation committee is William Landman. Our Board has determined that all members are independent under NYSE’s heightened independence standards for members of a compensation committee and as a “non-employee director” as defined in Rule 16b-3 of the Exchange Act.

The Compensation Committee did not meet in 2025. Compensation matters were discussed by members of the Compensation Committee at certain meetings of the Board and approved by unanimous written consents of the Compensation Committee.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee’s responsibilities include:

The Nominating and Corporate Governance Committee charter is available on our website at www.investors.zetaglobal.com. Our nominating and corporate governance committee consists of Jené Elzie, Imran Khan, and Jeanine Silberblatt. Our Board has determined that all members are independent under the NYSE listing rules. The chair of our nominating and corporate governance committee is Jené Elzie. The Nominating and Corporate Governance Committee has the authority to consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders.

The Nominating and Corporate Governance Committee met once in 2025.

Compensation Discussion and Analysis

General

In this Compensation Discussion and Analysis (“CD&A”), we provide an overview and analysis of the compensation awarded to or earned by our named executive officers identified in the Summary Compensation Table below (each, an “NEO”) during fiscal 2025, including the elements of our compensation program for NEOs, material compensation decisions made under that program for fiscal 2025 and the material factors considered in making those decisions. For the year ended December 31, 2025, our NEOs and their positions were:

Executive Summary

2025 Performance Highlights and Pay for Performance.

Our executive compensation programs are designed to deliver pay in accordance with corporate and individual performance, rewarding superior performance and providing consequences for underperformance. We believe that the compensation of our NEOs for fiscal year 2025 was aligned with the Company’s performance during 2025. Highlights of that performance include:

For additional details and definitions, refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2025 that accompanies this Proxy Statement.

In order to align pay with performance, a significant portion of our executive compensation program is based on equity awards and annual cash incentives, each of which depends on our actual performance.

2025 Compensation Highlights.

Consistent with our compensation philosophy, key compensation decisions for 2025 included the following:

Compensation Governance and Best Practices.

We are committed to having strong governance standards with respect to our compensation programs, procedures and practices. Our key compensation practices include the following:

Stockholder Advisory Vote on Executive Compensation

As required by Section 14A(a)(1) of the Exchange Act, in Proposal 3 of this Proxy Statement we are requesting that our stockholders vote to approve, on an advisory (non-binding) basis, the compensation of our NEOs as disclosed in this Proxy Statement. This proposal, commonly known as a “Say-on-Pay Vote”, gives our stockholders the opportunity to express their views on our NEOs’ compensation. Our Board and the Compensation Committee will consider the outcome of the Say-on-Pay Vote, as well as feedback received throughout the year, when making compensation decisions for our NEOs in the future.

A majority of the shares voting at our annual meeting of stockholders in 2025 voted in favor of our advisory vote on executive compensation, reflecting our stockholders’ support of our executive compensation program. Given the support received from our stockholders and the Compensation Committee’s assessment that our programs continue to effectively support our business objectives, we did not make any material changes to our executive compensation program as a result of this vote.

Executive Compensation Objectives and Philosophy

The key objective in our executive compensation program is to attract, motivate, and reward leaders who create an inclusive environment where individuals can succeed, regardless of background, and have the skills and experience necessary to successfully execute on our strategic plan to maximize stockholder value. Our executive compensation program is designed to:

We strive to set our overall total compensation at a competitive level. Executives may be compensated above or below the targeted market position based on factors such as experience, performance, scope of position and the competitive demand for proven executive talent, as described further below under “Determination of Executive Compensation.”

Determination of Executive Compensation

Role of Board of Directors, Compensation Committee and Executive Officers

The Compensation Committee is responsible for establishing and overseeing our executive compensation programs and annually reviews and determines the compensation to be provided to our NEOs.

In setting executive compensation, the Compensation Committee considers a number of factors, including the recommendations of our Chief Executive Officer (other than with respect to the Chief Executive Officer’s own compensation), current and past total compensation, competitive market data and analysis provided by the Compensation Committee’s independent compensation consultant, Company performance and each executive’s impact on performance, each executive’s relative scope of responsibility and potential, each executive’s individual performance and demonstrated leadership, and internal pay equity considerations. Our Chief Executive Officer’s recommendations are based on his evaluation of each other NEO’s individual performance and contributions, of which our Chief Executive Officer has direct knowledge. Our Compensation Committee makes decisions regarding our NEOs’ compensation, following review of these factors.

Role of Compensation Consultant

In order to design a competitive executive compensation program that will continue to attract top executive talent and reflect our compensation philosophy, our Compensation Committee has retained FW Cook as an independent compensation consultant to provide executive compensation advisory services, help evaluate our compensation philosophy and objectives and provide guidance in administering our executive compensation program. The Compensation Committee has evaluated the independence of FW Cook pursuant to the requirements of NYSE and SEC rules and has determined that FW Cook does not have any conflicts of interest in advising the Compensation Committee. FW Cook did not provide any other services to the Company in 2025 for which the amount of fees exceeded $120,000.

For purposes of 2025 executive compensation decisions, the Compensation Committee used the peer group developed in consultation with FW Cook in December 2024, which was selected based on an evaluation of other publicly traded companies with size and financial characteristics similar to our own, or which operate in similar industries. This peer group consisted of the following companies:

Elements of Compensation

The primary elements of our NEOs’ compensation and the main objectives of each are:

In addition, our NEOs are eligible to participate in our health and welfare programs and our 401(k) plan on the same basis as our other employees. We have also entered into employment agreements with each of our NEOs that

provide for severance payments and benefits under certain circumstances. We believe that offering these severance benefits aids in attracting and retaining executive talent and helps executives to remain focused and dedicated during potential transition periods due to a change in control. Each of these elements of compensation for 2025 is described further below.

Base Salary

The base salaries of our NEOs are an important part of their total compensation package, and are intended to reflect the executive’s skill set, experience, role and responsibilities. Base salary is a visible and stable fixed component of our compensation program. Base salaries provide our NEOs with a reasonable degree of financial certainty and stability. Our Compensation Committee annually reviews and determines the base salaries of our executives. None of the NEOs received an increase in base salary for 2025. The actual base salaries paid to each NEO for 2025 are set forth below in the “Summary Compensation Table” in the column entitled “Salary.”

Cash Incentive Compensation

We consider annual cash incentive bonuses to be an important component of our total compensation program and provide incentives necessary to retain executive officers. Each NEO is eligible to receive an annual performance-based cash bonus based on a specified target annual bonus award amount, expressed as a percentage of the NEO’s base salary. For 2025, the target bonus opportunity for Mr. Steinberg, Mr. Gerber and Mr. Greiner, expressed as a percentage of base salary was 100%, 109% and 100%, respectively.

Our Board determines the bonus amounts for our executives, including our NEOs, based on Company performance against pre-established objectives and retains discretion to allow for individual adjustments based on such factors as it deems appropriate. Payouts under our annual cash incentive program are made based on input from the Chief Executive Officer and the Compensation Committee on performance against a variety of factors, including financial performance against the Company’s budget for fiscal year 2025 that was presented to the Board in January 2025. After considering performance against the financial goals as well as an assessment of qualitative factors of performance including general market conditions and success on other strategic goals, the Chief Executive Officer recommended, and the Compensation Committee approved, annual incentive payouts at the 200% of the target level for all the NEOs based on the achievement of revenue and profitability that exceeded the Company’s 2025 financial budget. In particular, the Company achieved $1,304.7 million in revenue and $278.7 million in Adjusted EBITDA for fiscal year 2025, which exceeded the initial guidance we issued of $1,235 million to $1,245 million in revenue and $255.5 million to $257.5 million in Adjusted EBITDA based on our budget for fiscal year 2025.1

____________________

1 Adjusted EBITDA is a non-GAAP financial measure. See Appendix A for a reconciliation of Adjusted EBITDA to Net Loss and for a discussion of management’s use of non-GAAP measures.

In addition to amounts earned under our annual bonus plan for the year, the named executive officers were also awarded discretionary cash bonuses during 2025 in recognition of the successful completion of the Company’s acquisition of the enterprise business from Marigold Group, Inc. (the “Marigold Deal Bonus”).

Equity-Based Long-Term Incentive Awards

We view equity-based compensation as a critical component of our balanced total compensation program. Equity-based compensation creates an ownership culture among our employees that provides an incentive to contribute to the continued growth and development of our business and aligns the interests of executives with those of our stockholders. We do not currently have any formal policy for determining the number of equity-based awards to grant to NEOs.

Our Compensation Committee believes it is essential to provide equity-based compensation to our executive officers in order to link the interests and risks of our executive officers with those of our stockholders, reinforcing our commitment to ensuring a strong linkage between Company performance and pay. While no equity awards were granted to our NEOs in 2025, equity compensation remains an integral component of our compensation program.

In February 2025, the Company determined that 190.1% of the target number of PSUs issued in April 2024 were earned by the NEOs based on the 20-day volume-weighted average price of our Class A Stock of $21.54 for the performance quarter ended December 31, 2024. The earned PSUs vest over three years, with one-third vesting on the date on which the Company determined the number of PSUs that are eligible to vest and the remaining two-thirds vesting in eight quarterly installments following such determination date.

Retirement Savings

We maintain a 401(k) retirement savings plan for our employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs are eligible to participate in the 401(k) plan on the same terms as other full-time employees. The Internal Revenue Code (the “Code”) allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we match 25% of contributions made by participants in the 401(k) plan up to 6% of the employee contributions, and these matching contributions vest over a period of four years. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making matching contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation policies.

Employee Benefits and Perquisites

All of our full-time employees, including our NEOs, are eligible to participate in our health and welfare plans, including medical, dental and vision benefits, medical and dependent care flexible spending accounts, short-term and long-term disability insurance, and life insurance.

In addition, for 2025, we provided our NEOs with certain limited executive perquisites. For Mr. Steinberg, these included reimbursement of expenses associated with a Company-provided corporate apartment and certain club membership fees. For Mr. Steinberg, Mr. Greiner and Mr. Gerber, these included reimbursement of the cost of executive healthcare services. The amounts paid pursuant to these arrangements for 2025 are included in the “All Other Compensation” column of the Summary Compensation Table.

We believe the benefits described above are necessary and appropriate to provide a competitive compensation package to our NEOs.

Employment Agreements

We are party to employment agreements with each of our NEOs, which provide for severance payments and benefits upon certain terminations of employment, including upon the executive’s termination without cause or resignation for good reason. Our Compensation Committee believes that these types of arrangements are necessary to attract and retain executive talent and are a customary component of executive compensation. In particular, such arrangements can mitigate a potential disincentive for our NEOs when they are evaluating a potential acquisition of the Company and can encourage retention through the conclusion of the transaction. The payments and benefits provided under the employment agreements are designed to be competitive with market practices. A description of these agreements, as well as information on the estimated payments and benefits that our NEOs would have been eligible to receive as of December 31, 2025, are set forth in “Potential Payments Upon Termination or Change in Control” below.

Other Policies and Considerations

Clawback Policy. The Company has adopted a compensation recovery policy as required by Rule 10D-1 under the Securities Exchange Act of 1934, as amended, and the corresponding listing standards of the New York Stock Exchange. This policy provides for the mandatory recovery (subject to limited exceptions) from current and former officers of incentive-based compensation that was erroneously received during the three years preceding the date that the Company is required to prepare an accounting restatement. Covered restatements include both a restatement to correct an error that is material to previously issued financial statements or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. The amount required to be recovered is the excess of the amount of incentive-based compensation received over the amount that otherwise would have been received had it been determined based on the restated financial measure.

Derivatives Trading, Hedging, and Pledging Policies. Our Insider Trading Compliance Policy provides that no employee, officer, or director may acquire, sell, or trade in any interest or position relating to the future price of Company securities, such as a put option, a call option or a short sale, or engage in hedging transactions. In addition, our Insider Trading Compliance Policy provides that no employee, officer, or director may pledge Company securities as collateral to secure loans, except under certain limited circumstances approved in advance by our compliance officer. This prohibition means, among other things, that these individuals may not hold Company securities in a “margin” account, which would allow the individual to borrow against their holdings to buy securities, except as approved in advance by our compliance officer. There have been no such exceptions approved to date.

Policies and Practices Relating to the Grant of Stock Options. We do not grant stock options in anticipation of the release of material nonpublic information, and we do not time the release of material nonpublic information for the purpose of affecting the value of executive compensation. In the event material nonpublic information becomes known to the Compensation Committee before granting a stock option, the Compensation Committee will consider such information and use its business judgment to determine whether to delay the grant to avoid any appearance of impropriety. Although we do not have a formal policy with respect to the timing of our stock option grants, the Compensation Committee has historically granted such awards on a predetermined annual schedule. In fiscal year 2025, we did not grant stock options to our NEOs.

Section 409A. The Compensation Committee takes into account whether components of the compensation for our executive officers will be adversely impacted by the penalty tax imposed by Section 409A of the Code, and aims to structure these components to be compliant with or exempt from Section 409A to avoid such potential adverse tax consequences.

Section 162(m). Section 162(m) of the Code disallows a tax deduction to public companies for compensation in excess of $1 million paid to “covered employees”, which generally includes all NEOs. While the Compensation Committee may take the deductibility of compensation into account when making compensation decisions, the Compensation Committee will award compensation that it determines to be consistent with the goals of our executive compensation program even if such compensation is not deductible by us.

Accounting for Share-Based Compensation. We follow Financial Accounting Standard Board Accounting Standards Codification Topic 718, (“ASC Topic 718”), for our share-based compensation awards. ASC Topic 718 requires companies to measure the compensation expense for all share-based payment awards made to employees and directors based on the grant date “fair value” of these awards. This calculation is performed for accounting purposes and reported in the compensation tables below, even though our NEOs may never realize any value from their awards.

COMPENSATION COMMITTEE REPORT

The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis set forth above. Based on such review and discussions, the Compensation Committee has recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement.

Potential Payments Upon Termination or Change in Control

Executive Employment Agreements

We are party to employment agreements with each of our NEOs pursuant to which the NEOs are entitled to severance payments and benefits upon certain qualifying terminations of employment.

Mr. Steinberg

In the event Mr. Steinberg’s employment is terminated without Cause or Mr. Steinberg resigns for Good Reason (as defined below), he will be entitled to, subject to executing a release of claims, an amount equal to his annual base salary and annual target bonus generally payable over 12 months following his termination, a lump sum payment equal to a pro-rated annual target bonus, 12-months of the employer portion of the premium costs for COBRA coverage, full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based equity awards to the extent the applicable performance conditions are achieved within 12 months of Mr. Steinberg’s termination. In the event we have a change in control and during the 24-month period following the change in control Mr. Steinberg is terminated without Cause or resigns for Good Reason, Mr. Steinberg will be entitled to, subject to executing a release of claims and in lieu of any other severance, an amount equal to two times his annual base salary and annual target bonus paid in a lump sum, a lump sum payment equal to a pro-rated annual target bonus, 18 months of the employer portion of the premium costs for COBRA coverage, full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based equity awards to the extent the applicable performance conditions are achieved within 12 months of Mr. Steinberg’s termination. If Mr. Steinberg dies or he is terminated by the Company due to his disability, he or his estate is entitled to full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based awards to the extent the applicable performance conditions are achieved within 12 months of his termination. In the event Mr. Steinberg terminates employment for any reason other than Cause, he is entitled to be included in the slate for re-election to the Board at every stockholder meeting at which Mr. Steinberg’s term as a member of the Board would otherwise expire, to the extent he owns, directly or directly, at least 5% of our shares. In the event Mr. Steinberg is terminated for Cause and agrees to extend his non-solicitation agreement until the fifth anniversary of the date of our IPO, the equity awards granted to him prior to our IPO will continue to vest during such extended non-solicitation period. In the event we have a change in control, any equity awards held by Mr. Steinberg will vest in full.

For purposes of Mr. Steinberg’s employment agreement, “Cause” generally means his conviction of or plea of guilty or no-contest to a felony resulting from fraudulent acts against us that are reasonably likely to result in material harm to us. A “without Cause” termination under the employment agreement also includes the non-renewal of the

agreement by us or due to our inability to enter into a mutually acceptable successor employment agreement with Mr. Steinberg at the end of the then applicable term. For purposes of Mr. Steinberg’s employment agreement, “Good Reason” generally means, without his written consent, a reduction in his base salary or target annual bonus, a diminution of his duties, responsibilities, powers or authorities, the requirement that his principal office location is moved more than 50 miles from the then office location, a material breach by us of the employment agreement or any other written agreement between us and Mr. Steinberg and a failure of a successor to assume the employment agreement in the event we incur a change in control.

Mr. Steinberg is also subject to standard confidentiality and intellectual property provisions, as well as a 12-month non-solicitation of customers, vendors, suppliers, business development partners and employees.

Mr. Greiner and Mr. Gerber

The employment agreements with Mr. Greiner and Mr. Gerber provide that in the event that either Mr. Gerber’s or Mr. Greiner’s employment is terminated without Cause or he resigns for Good Reason (as defined below), he will be entitled to, subject to executing a release of claims and in lieu of any other severance, an amount equal to his annual base salary and annual target bonus generally payable over 12 months following his termination, a lump sum payment equal to a pro-rated annual target bonus, 12 months of the employer portion of the premium costs for COBRA coverage, full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based equity awards to the extent the applicable performance conditions are achieved within 12 months of termination. In the event we have a change in control and during the 24-month period following the change in control Mr. Greiner or Mr. Gerber is terminated without Cause or resigns for Good Reason, he will be entitled to, subject to executing a release of claims and in lieu of any other severance, an amount equal to two times his annual base salary and annual target bonus paid in a lump sum, a lump sum payment equal to a pro-rated annual target bonus, 18 months of the employer portion of the premium costs for COBRA coverage, full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based equity awards to the extent the applicable performance conditions are achieved within 12 months of his termination. Each employment agreement also provides that in the event that either Mr. Gerber’s or Mr. Greiner’s employment is terminated due to death or by the Company due to his disability, he or his estate will be entitled to full vesting of his outstanding time-based equity awards and vesting of his outstanding performance-based equity awards to the extent the applicable performance conditions are achieved within 12 months of termination. In the event we have a change in control, any equity awards held by Mr. Greiner or Mr. Gerber will vest in full.

For purposes of Mr. Greiner’s and Mr. Gerber’s employment agreements, “Cause” generally means his conviction of or plea of guilty or no-contest to a felony that is reasonably likely to adversely and significantly affect our business, his willful and repeated failure or refusal to perform reasonably assigned duties which is materially harmful to the business, willful misconduct which is materially harmful to the business, or a material breach of the employment agreement or fiduciary duty, which is likely to adversely and significantly affect the business. For purposes of the employment agreement, “Good Reason” generally means, without his written consent, a reduction in his base salary or target annual bonus, a material diminution of his duties, responsibilities, powers or authorities, the requirement that his principal office location is moved more than 50 miles from the then office location, a material breach by us of the employment agreement or any other written agreement between us and a failure of a successor to assume the employment agreement in the event we incur a change in control.

PSUs

Under the terms of the PSU agreements, the NEOs’ PSUs would be eligible to vest in connection with certain qualifying terminations of employment or a change in control as follows:

Death or Disability. Upon termination due death or by the Company due to disability, any earned but unvested PSUs will accelerate and vest on the date of such termination.

Termination without Cause or Resignation for Good Reason. In the event a named executive officer’s employment is terminated by the Company without cause or by the named executive officer for good reason, subject to executing a release of claims, (i) any earned but unvested PSUs will accelerate and vest on the date of such termination and (ii) unearned PSUs will remain outstanding and eligible to vest based on performance for the performance quarter in which the date of termination occurs.

Change in Control. In the event of a change in control, and subject to the executive’s continued service through the date of such change in control, (i) any earned but unvested PSUs will vest on the date of such change in control and (ii) any unearned PSUs will vest on the date of such change in control based on the target number of PSUs that would have been earned based on performance, provided that, for such purpose, the 20 day volume-weighted average closing price will be deemed to equal the price or implied price per share of Class A Stock in such change in control.

Estimated Potential Payments

The following table summarizes the payments that would be made to our NEOs upon the occurrence of certain qualifying terminations of employment or a change in control, in any case, occurring on December 31, 2025. Amounts shown do not include (i) accrued but unpaid base salary through the date of termination or (ii) other benefits earned or accrued by the NEO during his employment that are available to all salaried employees, such as accrued vacation.

____________________

(1) Includes pro-rated bonus amounts for fiscal 2025 based on full target bonus amounts.

(2) In the event Mr. Steinberg is terminated for cause and agrees to extend his non-solicitation agreement until the fifth anniversary of the date of our IPO, the equity awards granted to him prior to our IPO will continue to vest during such extended non-solicitation period.

(3) With respect to restricted shares and earned but unvested PSUs, the value of equity acceleration was calculated by multiplying the number of accelerated shares by $20.35, the closing price of our Class A Stock on the last trading day of fiscal 2025.

2025 Director Compensation

The following table sets forth the compensation earned by our non-employee directors for their service on our Board during 2025.

____________________

(1) Amounts reflect the annual cash retainer earned under our director compensation program for service on our Board during 2025. For Mr. Landman and Mr. Sculley, these directors each elected to receive their quarterly payment of their annual cash retainer in the form of restricted shares of our Class A Stock, which vests as to 25% of the award one year from the grant date and as to the remaining 75% in four equal quarterly installments beginning on the first anniversary of the grant date. Accordingly, these directors were each granted the following restricted shares of our Class A Stock in lieu of $25,000 of cash fees for service during the applicable quarter of 2025: (i) for both Mr. Landman and Mr. Sculley, 1,843 restricted shares on April 1, 2025 for service during the first quarter of 2025; and (ii) for Mr. Landman, 1,614 restricted shares on July 1, 2025 for service during the second quarter of 2025; 1,258 restricted shares on October 1, 2025 for service during the third quarter of 2025; and 1,228 restricted shares on January 1, 2026 for service during the fourth quarter of 2025.

(2) Amounts reflect the full grant-date fair value of restricted stock awards granted during 2025 computed in accordance with ASC Topic 718, rather than the amounts paid to or realized by the named individual. We provide information regarding the assumptions used to calculate the value of all restricted stock awards made to our directors in Note 13 to the consolidated financial statements included in our 2025 Annual Report on Form 10-K.

(3) In December 2025, Mr. Khan elected to forfeit his outstanding unvested restricted stock awards and no longer participate in the Company’s non-employee director compensation program beginning in the fourth quarter of 2025, pursuant to guidelines adopted by Proem Advisors LLC, the entity for which Mr. Khan serves as Chief Investment Officer. In connection with this election, Mr. Khan disposed of 14,028 restricted shares of Class A Stock to the Company for no value on December 17, 2025.

The table below shows the aggregate number of unvested stock awards held as of December 31, 2025 by each non-employee director. Certain outstanding awards have been transferred by the director to trusts or other entities. None of our non-employee directors hold any option awards.

Director Compensation Program

We maintain a compensation program for our non-employee directors under which each non-employee director is eligible for (i) an annual equity award of $150,000 in shares of restricted stock on July 1 of each year, subject to the director’s continued service as a director through such date; and (ii) an annual cash retainer of $100,000, payable in arrears in four equal quarterly installments, prorated for the portion of each calendar quarter actually served as a

non-employee director. The restricted shares granted under the director compensation program vest as to 25% of the shares on the date of grant and as to 25% of the shares on each October 1, January 1 and April 1 thereafter, subject to continued service as a non-employee director through each such vesting date and accelerated vesting upon a change in control.

Under our director compensation program, each non-employee director may elect to receive restricted shares of our Class A Stock in lieu of the director’s quarterly cash retainer for Board service. The restricted shares granted in lieu of the cash retainer vest as to 25% of the award one year from the grant date and as to the remaining 75% in four equal quarterly installments beginning on the first anniversary of the grant date. The number of shares payable at the end of each quarter is determined by dividing the cash amount of the retainer by the closing price of our Class A Stock on the final trading day of such quarter. Cash is paid in lieu of any fractional shares.

* * * * *

CEO Pay Ratio

As required by Section 953(b) of the Dodd-Frank Act and Item 402(u) of Regulation S-K, we are required to disclose the ratio of our Chief Executive Officer’s annual total compensation to the annual total compensation of our other employees.

The annual total compensation for 2025 for our Chief Executive Officer was $6,083,236, as reported in the Summary Compensation Table. The annual total compensation for 2025 for our median employee, identified as discussed below, was $102,694, calculated in accordance with the rules applicable to the Summary Compensation Table. Based on this information, for 2025, the ratio of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of our other employees was approximately 59 to 1.

Methodology, Assumptions and Estimates Used in Determining our Pay Ratio Disclosure

As permitted under SEC rules, we are using the same median employee for our 2025 pay ratio calculation as we used for our 2024 pay ratio calculation because we did not experience any meaningful changes in our employee population or employee compensation arrangements during 2025 that we reasonably believe would significantly impact our pay ratio disclosure.

The annual total compensation of the median employee and the annual total compensation of the CEO were calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported above should not be used as a basis for comparison between companies by other companies. In addition, we expect the Company’s annually reported pay ratio may vary significantly year over year, given the size of the Company and the potential variability in Company employee compensation.

* * * * *

Compensation Risk Assessment

We have assessed our compensation programs for all employees and concluded that our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on us. Management has evaluated our executive and employee compensation and benefits programs to determine if these programs’ provisions and operations create undesired or unintentional risk of a material nature. The risk assessment process includes a review of program policies and practices; analysis to identify risks and risk controls related to our compensation programs; and determinations as to the sufficiency of risk identification, the balance of potential risk to potential reward, the effectiveness of our risk controls and the impacts of our compensation programs and their risks to our strategy. Although we periodically review all compensation programs, we focus on the programs with variability of payout, with the ability of a participant to directly affect payout and the controls on participant action and payout. In relation to this, we believe that our incentive compensation arrangements provide incentives that do not encourage risk taking beyond our ability

to effectively identify and manage significant risks and are compatible with effective internal controls and our risk management practices.

The Compensation Committee monitors our compensation programs on an annual basis and expects to make modifications as necessary to address any changes in our business or risk profile.

The charts below show, for the past five years, the relationship of the Company’s TSR relative to the Company’s TSR peer group as well as the relationship between the CEO and Other NEOs’ “compensation actually paid” and (i) the Company’s TSR; (ii) the Company’s net income / (loss); and (iii) the Company-Selected Measure, Adjusted EBITDA.

Equity Compensation Plan Information

As of December 31, 2025, the following securities were authorized for issuance under our equity compensation plans.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following sets forth the beneficial ownership of Zeta’s Class A Stock and Class B Stock as of April 17, 2026 by:

The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which a person has sole or shared voting power or investment power. Applicable percentage ownership is based on 225,609,644 shares of Class A Stock and 23,638,426 shares of Class B Stock outstanding as of April 17, 2026. “Percentage of Total Voting Power” represents voting power with respect to all outstanding shares of our Class A Stock and Class B Stock, as a single class, as of April 17, 2026. The holders of our Class B Stock are entitled to 10 votes per share, and holders of our Class A Stock are entitled to one vote per share. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of our Common Stock subject to options, warrants or other rights held by such person that are currently exercisable or will become exercisable within 60 days of April 17, 2026 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

Unless otherwise indicated, Zeta believes that all persons named in the table below have sole voting and investment power with respect to the voting securities beneficially owned by them.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

Policies and Procedures for Related Person Transactions

Our Board has adopted a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions. Under the policy, our legal team is primarily responsible for developing and implementing processes and procedures to obtain information regarding related persons with respect to potential related person transactions and then determining, based on the facts and circumstances, whether such potential related person transactions do, in fact, constitute related person transactions requiring compliance with the policy. If our legal team determines that a transaction or relationship is a related person transaction requiring compliance with the policy, our legal department is required to present to the Audit Committee all relevant facts and circumstances relating to the related person transaction. Our Audit Committee must review the relevant facts and circumstances of each related person transaction, including if the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party and the extent of the related person’s interest in the transaction, take into account the conflicts of interest and corporate opportunity provisions of our Code of Ethics and Conduct, and either approve or disapprove the related person transaction. If advance Audit Committee approval of a related person transaction requiring the Audit Committee’s approval is not feasible, then the transaction may be preliminarily entered into by management upon prior approval of the transaction by the chairperson of the Audit Committee subject to ratification of the transaction by the Audit Committee at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. If a transaction was not initially recognized as a related person, then upon such recognition the transaction will be presented to the Audit Committee for ratification at the Audit Committee’s next regularly scheduled meeting; provided, that if ratification is not forthcoming, management will make all reasonable efforts to cancel or annul the transaction. Our management will update the Audit Committee as to any material changes to any approved or ratified related person transaction and will provide a status report at least annually of all then current related person transactions. No director may participate in approval of a related person transaction for which he or she is a related person.

All transactions described below that were entered into following the closing of our IPO in 2021 were undertaken in compliance with our Related Person Transaction Policy described above, including review and approval by our Audit Committee.

Policies and Procedures for Transactions with Related Persons

We have adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our Common Stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a related person transaction with us without the approval or ratification of our audit committee. Any request for us to enter into a transaction with an executive officer, director, nominee for election as a director, beneficial owner of more than 5% of any class of our Common Stock or any member of the immediate family of any of the foregoing persons, in which such person would have a direct or indirect material interest, must be presented to our Board or our audit committee for review, consideration and approval. In approving or rejecting any such proposal, our audit committee is to consider the relevant facts of the transaction, including whether the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party and the extent of the related person’s interest in the transaction, and shall also take into account the conflicts of interest and corporate opportunity provisions of our Code of Ethics and Conduct.

Appendix A – Non-GAAP Financial Information

We use the following financial information that is not in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) to evaluate our ongoing operations and for internal planning and forecasting purposes. Non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly titled non-GAAP measures used by other companies. Whenever we use a non-GAAP financial measure, a reconciliation is provided to the most closely applicable financial measure stated in accordance with GAAP. We believe that these non-GAAP financial measures may be useful to investors in analyzing our financial and operational performance.

Adjusted EBITDA and Adjusted EBITDA Margin

Adjusted EBITDA is a non-GAAP financial measure defined as net income / (loss) adjusted for interest expense, net, depreciation and amortization, stock-based compensation, income tax (benefit) / provision, acquisition-related expenses, restructuring expenses, change in fair value of warrants and derivative liabilities, certain dispute settlement expenses, gain on extinguishment of debt, certain non-recurring capital raise related (including IPO) expenses, including the payroll taxes related to vesting of restricted stock and restricted stock units upon the completion of the IPO, and other expenses. Acquisition-related expenses and restructuring expenses primarily consist of professional services fees, severance and other employee-related costs, which may vary from period to period depending on the timing of our acquisitions and restructuring activities and may distort the comparability of the results of operations. Change in fair value of warrants and derivative liabilities is a non-cash expense related to periodically recording “mark-to-market” changes in the valuation of derivatives and warrants. Other expenses consist of non-cash expenses such as changes in fair value of acquisition-related liabilities, gains and losses on extinguishment of acquisition-related liabilities, gains and losses on sales of assets and foreign exchange gains and losses. In particular, we believe that the exclusion of stock-based compensation, certain dispute settlement expenses and non-recurring capital raise related (including IPO) expenses that are not related to our core operations provides measures for period-to-period comparisons of our business and provides additional insight into our core controllable costs. We exclude these charges because these expenses are not reflective of ongoing business and operating results. Adjusted EBITDA margin is a non-GAAP metric defined as adjusted EBITDA divided by the total revenues for the same period.

Adjusted EBITDA and adjusted EBITDA margin provide us with a useful measure for period-to-period comparisons of our business as well as comparison to our peers. Our use of adjusted EBITDA and adjusted EBITDA margin has limitations as an analytical tool, and you should not consider these measures in isolation or as a substitute for analysis of our financial results as reported under GAAP. Because of these and other limitations, you should consider our non-GAAP measures only as supplemental to other GAAP-based financial performance measures, including revenues and net income / (loss).

The following table reconciles adjusted EBITDA and adjusted EBITDA margin to net loss and net loss margin, the most directly comparable financial measure calculated and presented in accordance with GAAP.
